Example 1
Fig. 1 is a flowchart of a data transmission method according to a first embodiment of the present invention, where the method may be applied to a data transmission case, and the method may be performed by a data transmission device, where the data transmission device may be implemented in hardware and/or software, and the data transmission device may be integrated in any electronic device that provides a data transmission function. As shown in fig. 1, the method is performed by a data sender, and the data transmission method includes:
s101, acquiring attribute information of a data sender and attribute information of a data receiver.
Wherein the data sender may be a device that sends data out and the data receiver may be a device that receives data. In the actual operation process, the same device can simultaneously send data and receive data, namely, the same device can simultaneously serve as a data sender and a data receiver, and full duplex data transmission can be realized.
The attribute information of the data transmitting side may include the capability of how many bits of data the device transmitting data to the outside can transmit to the outside at a time (for example, 4 bits of data or 8 bits of data may be transmitted to the outside at a time), a rule of transmitting higher order data or lower order data first, and the like. The attribute information of the data receiving side may include the capability of how many bits of data the device receiving the data can receive at a time (for example, 4 bits of data or 8 bits of data can be received at a time), a rule of first receiving high order data or low order data, and the like.
Specifically, before data transmission is performed between two devices of a data sender and a data receiver, the attribute of the data sender and the attribute of the data receiver are respectively configured by the two devices, the data sender acquires attribute information of the data receiver, whether the data transmission can be performed between the two devices is determined, and if the data sender and the data receiver configure the same attribute information, the two devices can perform data transmission. For example, the attribute information configured by the data sender may be that 4 bits of data can be sent out at a time, and the higher bits of data are sent first and then the lower bits of data are sent, and the attribute information configured by the data receiver may be that 4 bits of data can be received at a time, and the higher bits of data are received first and then the lower bits of data are received. Of course, if it is desired to perform transmission of 8 bits of data at a time between the data sender and the data receiver, the attribute of the data sender needs to be configured to be able to send 8 bits of data out at a time, and the attribute of the data receiver needs to be configured to be able to receive 8 bits of data at a time.
In actual operation, for example, the SPI (Serial Peripheral Interface ) communication function of the microcontroller MCU (Micro Control Unit) may be set by configuring relevant registers of the MCU to enable the SPI to operate in various modes (e.g., transmit mode or receive mode), specifically as a master or as a slave, and whether the SPI transmits byte data in high order or low order, etc., which may be an initialization configuration by the MCU prior to data transmission.
S102, determining transmission format information according to the attribute information of the data sender and the attribute information of the data receiver.
The transmission format information may be how many bits of data are transmitted at a time when the data is transmitted to the outside (for example, 4 bits of data or 8 bits of data are transmitted to the outside at a time), or may be higher bits of data or lower bits of data are transmitted first when the data is transmitted to the outside (for example, 4 bits of data are transmitted to the outside at a time, one byte of data is composed of 8 bits of data, higher 4 bits of data out of 8 bits of data are transmitted first and lower 4 bits of data out of 8 bits of data are transmitted first and higher 4 bits of data out of 8 bits of data are transmitted first).
Specifically, the transmission format information is determined according to the attribute information of the data sender and the attribute information of the data receiver, for example, how many bits of data are transmitted at a time when the data sender sends data outwards, and whether the data sender sends high-order data or low-order data first when the data sender sends data outwards.
S103, determining data to be transmitted according to the transmission format information, and transmitting the data to be transmitted to a data receiver.
The data to be transmitted may be data processed by the data transmitter according to the transmission format information, where the data to be transmitted to the outside is transmitted. For example, the data to be sent to the outside by the data sender is 0xD5 (here, in the hexadecimal representation, the decimal number corresponding to the hexadecimal number D5 is 213), if the sending format information determined according to the attribute information of the data sender and the attribute information of the data receiver sends 4 bits of data to the outside by the data sender Fang Yici, and sends the upper 4 bits of data first and sends the lower 4 bits of data first, the 0xD5 is split into the upper 4 bits of data 0xD and the lower 4 bits of data 0x5, and the upper 4 bits of data 0xD and the lower 4 bits of data 0x5 are the data to be sent.
Specifically, the data to be sent outwards by the data sender is processed according to the sending format information, then the data to be sent is determined as the data to be sent, and the data to be sent is sent to the data receiver. For example, the data 0xD5 to be sent outwards by the data sender may be split into the high 4-bit data 0xD and the low 4-bit data 0x5 of the data to be sent, and the high 4-bit data 0xD and the low 4-bit data 0x5 of the data to be sent are sequentially sent to the data receiver.
Of course, if the data to be sent outwards by the data sender is 0xD5, and the sending format information determined according to the attribute information of the data sender and the attribute information of the data receiver can send 8 bits of data outwards at a time by the data sender, the data 0xD5 is directly determined as the data to be sent without splitting the data 0xD5, and the data 0xD5 to be sent is sent to the data receiver.
According to the embodiment of the invention, the attribute information of the data sender and the attribute information of the data receiver are obtained, the sending format information is determined according to the attribute information of the data sender and the attribute information of the data receiver, the data to be sent is determined according to the sending format information, and the data to be sent is sent to the data receiver, so that the data transmission between the data sender and the data receiver is realized.
Optionally, determining the transmission format information according to the attribute information of the data sender and the attribute information of the data receiver includes:
the first number of bits is determined based on the attribute information of the data sender and the attribute information of the data receiver.
The first bit number may be the number of how many bits of data the data sender can send out at a time, and the data receiver can receive how many bits of data at a time. Specifically, the first number of bits may be determined according to attribute information of the data sender and attribute information of the data receiver.
Specifically, the number of bits of data which are transmitted by the data transmitter at one time is determined according to the attribute information of the data transmitter, and the number of bits of data which can be received by the data receiver at one time is determined according to the attribute information of the data receiver.
The transmission format information is determined according to the first number of bits.
Specifically, the transmission format information is determined according to the first number of bits. For example, if the first number of bits is 4, the transmission format information may be to split one byte of data into two parts, each part consisting of 4 bits of data, for example, splitting data 0xD5 into high 4 bits of data 0xD and low 4 bits of data 0x5; if the first bit number is 8, the transmission format information may be that data of one byte is directly transmitted without splitting.
In the actual operation process, whether the data sender and the data receiver send the high 4-bit data first or send the low 4-bit data first can also be determined according to the attribute information of the data sender and the attribute information of the data receiver.
Optionally, determining the data to be sent according to the sending format information, and sending the data to be sent to the data receiver, including:
A synchronous clock signal is acquired.
It will be appreciated that the clock signal is the basis of sequential logic for determining when the state in the logic cells is updated, and is a fixed period, operation independent semaphore. In this embodiment, the synchronization clock signal may be a signal for controlling the data transmission from the data transmission side to the data reception side.
Specifically, the synchronous clock signal of the data sender is obtained, and when the synchronous clock signal of the data sender is at a high level, the data sender does not send data to the data receiver; when the synchronous clock signal of the data sender is low level, the data sender sends data to the data receiver.
And splitting the target data according to the first bit quantity to obtain at least one data to be transmitted.
It should be explained that the splitting operation may be to split the target data according to the first number of bits.
For example, if the first bit number is 4, splitting the target data 0xD5 into two data to be sent, namely high 4-bit data 0xD and low 4-bit data 0x5; if the first bit number is 8, the target data 0xD5 is directly determined as the data to be sent without splitting the target data 0xD 5.
And sequentially transmitting at least one data to be transmitted to a data receiver according to the synchronous clock signal.
Specifically, after the data to be transmitted is determined, the data to be transmitted is sequentially transmitted to the data receiver when the synchronous clock signal of the data transmitter is at a low level according to the transmission sequence determined according to the attribute information of the data transmitter and the attribute information of the data receiver. The determined transmission sequence may be to transmit the high-order data first and then transmit the low-order data, or may be to transmit the low-order data first and then transmit the high-order data.
Optionally, sequentially sending at least one data to be sent to the data receiver includes:
and D, performing digital-to-analog conversion on the at least one data to be transmitted to obtain at least one first transmission data.
In this embodiment, digital-to-analog conversion refers to converting a digital signal into an electrical signal, where the electrical signal may be a voltage signal or a current signal. Specifically, the digital-to-analog conversion process may be performed by a DAC (Digital Analog Change, digital-to-analog conversion) module installed at the data transmitter.
It should be noted that, the first transmission data may be data to be transmitted by the data transmitting side after performing digital-to-analog conversion on the data to be transmitted.
Specifically, at least one data to be transmitted is subjected to digital-to-analog conversion and converted into an electrical signal (the electrical signal may be a voltage signal or a current signal), so as to obtain at least one first transmission data.
In the actual operation process, two devices of a data sender and a data receiver for data transmission determine the value range of the transmitted electric signal (the maximum value in the value range of the electric signal can be the reference voltage of an ADC module and a DAC module of the data sender and the data receiver, for example), and if the reference voltages of the two devices are inconsistent, the data cannot be normally communicated. Taking voltage signal transmission as an example, for example, the reference voltages of the ADC module and the DAC module of both the data sender and the data receiver are 2560 millivolts, the voltage signal value range may be a minimum value of 0 volts and a maximum value of 2560 millivolts. For example, if the target data is 0xD5, if the first bit number is 4, since the 4-bit data can represent 16 values ranging from 0 to 15, the maximum voltage 2560 millivolts can be divided into 16 parts, i.e. 160 millivolts for each part, so that the corresponding relationship between the 4-bit data and the voltage signal can be obtained, i.e. a=160×d (millivolts), where a is the voltage signal value corresponding to the data to be sent, the unit is millivolts, and D is the data to be sent. Through calculation, the voltage signal value corresponding to the target data 0xD5, the low 4-bit data 0x5 is 800 millivolts, the voltage signal value corresponding to the high 4-bit data 0xD is 2080 millivolts, that is, 800 millivolts and 2080 millivolts are two first sending data.
At least one first transmission data is sequentially transmitted to a data receiver.
Specifically, the data sender sequentially sends at least one first sending data to the data receiver according to the sending sequence. For example, the first sending data corresponding to the high-order data after digital-to-analog conversion is sent to the data receiver, and then the first sending data corresponding to the low-order data after digital-to-analog conversion is sent to the data receiver; or the first sending data corresponding to the low-order data after digital-to-analog conversion is sent to the data receiver, and the first sending data corresponding to the high-order data after digital-to-analog conversion is sent to the data receiver.
Example two
Fig. 2 is a flowchart of a data transmission method according to a second embodiment of the present invention, where the method may be applied to a data transmission case, and the method may be performed by a data transmission device, where the data transmission device may be implemented in hardware and/or software, and the data transmission device may be integrated in any electronic device that provides a data transmission function. As shown in fig. 2, the method is performed by a data receiving side, and the data transmission method includes:
s201, acquiring attribute information of a data sender and attribute information of a data receiver.
Specifically, before data transmission is performed between two devices of a data sender and a data receiver, the data receiver firstly acquires attribute information of the data sender and attribute information of the data receiver, and determines that the data transmission can be performed between the two devices. For example, the attribute information of the data sender may be that 4 bits of data can be sent out at a time, and the higher bits of data are sent first and then the lower bits of data are sent, and the attribute information of the data receiver may be that 4 bits of data can be received at a time, and the higher bits of data are received first and then the lower bits of data are received.
S202, receiving format information is determined according to the attribute information of the data sender and the attribute information of the data receiver.
The receiving format information may be how many bits of data are received at a time (e.g., 4 bits of data or 8 bits of data are received at a time) when the data receiving side receives data, or may be whether higher bits of data are received at first or lower bits of data are received at a time when the data receiving side receives data (e.g., 4 bits of data are received at a time, one byte of data is composed of 8 bits of data, higher 4 bits of data are received first and lower 4 bits of data are received first, or lower 4 bits of data are received first and higher 4 bits of data are received first.
Specifically, the receiving format information is determined according to the attribute information of the data sender and the attribute information of the data receiver, for example, how many bits of data are received at a time when the data receiver receives the data, and whether the data receiver receives the high-order data or the low-order data at first when the data receiver receives the data.
And S203, splicing the received data according to the receiving format information to obtain target data.
It should be noted that the splicing may be to splice and combine the data received by the data receiving party according to the receiving format information.
Specifically, the data receiver splices and combines the received data according to the receiving format information. For example, if the reception format information is that the data receiver receives 4-bit data at a time and receives first high-order data and then low-order data, the data receiver uses the first received 4-bit data as high-order data, uses the later received 4-bit data as low-order data, and concatenates two 4-bit data into one 8-bit, i.e., 1-byte, target data.
According to the embodiment of the invention, the attribute information of the data sender and the attribute information of the data receiver are obtained, the receiving format information is determined according to the attribute information of the data sender and the attribute information of the data receiver, the received data is spliced according to the receiving format information, the target data is obtained, and the data transmission between the data sender and the data receiver is completed.
Optionally, determining the receiving format information according to the attribute information of the data sender and the attribute information of the data receiver includes:
the first number of bits is determined based on the attribute information of the data sender and the attribute information of the data receiver.
Specifically, the number of bits of data which are transmitted by the data transmitter at one time is determined according to the attribute information of the data transmitter, and the number of bits of data which can be received by the data receiver at one time is determined according to the attribute information of the data receiver.
The reception format information is determined according to the first number of bits.
Specifically, the reception format information is determined according to the first number of bits. For example, if the first number of bits is 4, the receiving format information may be to first receive one 4 bits of data and then receive one 4 bits of data, for example, first receive the high 4 bits of data 0xD and then receive the low 4 bits of data 0x5; alternatively, the low 4-bit data 0x5 is received first and then the high 4-bit data 0xD is received. If the first number of bits is 8, the reception format information may be one byte of data received directly.
Optionally, splicing the received data according to the received format information to obtain target data, including:
Time information of the received data is acquired.
The time information may be time sequence information of the data receiver receiving at least one transmission data transmitted by the data transmitter.
Specifically, time information that the data receiving side receives at least one transmission data transmitted by the data transmitting side is acquired.
And splicing the received data according to the receiving format information and the time information to obtain target data.
Specifically, according to the receiving format information and the time information of the data receiving party receiving at least one data, the received at least one data is spliced to obtain the target data. For example, when the data receiving party receives data, the receiving party receives 4 bits of data at a time, receives the upper 4 bits of data and then receives the lower 4 bits of data, the data receiving party receives one 4 bits of data 0xD, receives one 4 bits of data 0x5, and splices the received data 0xD and 0x5 according to the receiving format information and the time information to obtain the target data 0xD5.
Optionally, splicing the received data according to the received format information and the time information to obtain target data, including:
and carrying out analog-to-digital conversion on the received data to obtain first data.
In this embodiment, analog-to-digital conversion refers to converting an electrical signal into a digital signal, where the electrical signal may be a voltage signal or a current signal. In particular, the analog-to-digital conversion process may be performed by an ADC (Analog Digital Change, analog-to-digital conversion) module installed at the data transmitter.
It should be noted that the first data may be data obtained by performing analog-to-digital conversion on data received by the data receiving party.
Specifically, the data received by the data receiving party is subjected to analog-to-digital conversion, and an electric signal (the electric signal may be a voltage signal or a current signal) is converted into a digital signal, so as to obtain first data.
And splicing the first data according to the receiving format information and the time information.
Specifically, the data receiver splices the first data according to the receiving format information and the time information to obtain target data, and completes data transmission.
Example III
Fig. 3 is a schematic diagram of a data transmission method according to a third embodiment of the present invention. The embodiment is applicable to the data transmission situation, and the method can be jointly executed by a data sender and a data receiver.
As shown in fig. 3, the main device, the peripheral device 1, and the peripheral device 2 each include a chip select signal line CS (Chip Select), a synchronization Clock signal line CK (Clock), a data reception signal line DI (Data Input), and a data transmission signal line DO (Data Output). The master device, the peripheral device 1, and the peripheral device 2 can all function as a data sender and a data receiver. Taking a master device as an example, description will be made of each signal line:
The master device can control the chip select signal CS and send the synchronous clock CK, and can realize connection and data transmission with the peripheral device 1 and the peripheral device 2 by controlling and enabling different chip select signals, namely, the chip select signal CS1 controls connection and data transmission with the peripheral device 1, and the chip select signal CS2 controls connection and data transmission with the peripheral device 2.
One chip select signal line CS in the master device corresponds to one peripheral device, the chip select signal line CS is at a high level when idle, the low level gating enables the device with which data is desired to be transmitted, and the signal lines (CK, DI and DO) of the ungated devices are set to a high impedance state, equivalent to disconnection, without affecting the data signal being transmitted on the bus.
The synchronous clock signal line CK in the main equipment is at a high level when idle, the data is output on the falling edge, the data is sampled on the rising edge, and multi-bit data such as 4 bits or 8 bits are transmitted in one clock period so as to improve the transmission rate.
The data lines in the main equipment are divided into a transmitting data line DO and a receiving data line DI, wherein the transmitting data line DO can convert digital signals into electric signals through the DAC module and transmit the electric signals, the receiving data line DI can convert the electric signals into the digital signals through the ADC module and receive the digital signals, namely, the equipment can transmit and receive data simultaneously, and full duplex data transmission can be realized.
The data transmission method will now be described taking the example in which the host device transmits data to the peripheral device 1 and converts the digital signal into a voltage signal:
first, two devices of a data transmitting side and a data receiving side for data transmission determine a transmitted electric signal value range (a maximum value in the electric signal value range may be, for example, reference voltages of an ADC module and a DAC module of the data transmitting side and the data receiving side), and if the reference voltages of the two devices are inconsistent, the data cannot be normally communicated. Taking voltage signal transmission as an example, for example, the reference voltages of the ADC module and the DAC module of both the data sender and the data receiver are 2560 millivolts, the voltage signal value range may be a minimum value of 0 volts, and a maximum value of 2560 millivolts, for example, the master device sends one byte of data 0xD5 to the peripheral device 1.
If it is determined that the transmission format information is 4-bit data to be transmitted to the outside of the data transmission Fang Yici and the upper 4-bit data is transmitted first and then the lower 4-bit data is transmitted according to the attribute information of the data transmission side and the attribute information of the data reception side, the target data 0xD5 is split into the upper 4-bit data 0xD and the lower 4-bit data 0x5. Since the 4-bit data can represent 16 values in the range of 0-15, the maximum voltage 2560 millivolts can be equally divided into 16 parts, namely 160 millivolts for each part, so that the corresponding relation between the 4-bit data and the voltage signal can be obtained, namely a=160×d (millivolts), wherein a is the voltage signal value corresponding to the data to be transmitted, the unit is millivolts, and D is the data to be transmitted. Through calculation, the voltage signal value corresponding to the sent target data 0xD5 and the low 4-bit data 0x5 is 800 millivolts, and the voltage signal value corresponding to the high 4-bit data 0xD is 2080 millivolts. Taking the example of transmitting the lower 4 bits of data first and then the upper 4 bits of data.
Fig. 4 is a schematic diagram of signal variation in a data transmission method according to a third embodiment of the present invention. As shown in fig. 4, at the beginning of the transmission, the master first pulls down the chip select signal CS1 of peripheral device 1, gating communication with peripheral device 1. The master device sends the low 4-bit data 0x5 to the DAC, and the master device outputs the synchronous clock CK at the first falling edge, converts the data 0x5 in the DAC into a voltage signal value of 800 millivolts and outputs the voltage signal value to the data transmission signal line DO and maintains the current electric signal value. When the master outputs the first rising edge of the synchronization clock CK, the peripheral device 1 samples the data reception signal line DI of the peripheral device 1 (i.e., the data transmission signal line DO of the master), and converts the voltage signal value on the line by 800 millivolts back to the digital signal quantity 0x5 with the ADC of the peripheral device 1. The master device sends the high 4-bit data 0xD to the DAC, and the master device outputs a synchronous clock CK with a second falling edge, converts the data 0xD in the DAC into a voltage signal value 2080 mV, outputs the voltage signal value 2080 mV to a data transmission signal line DO and maintains the current electric signal value. When the master outputs the second rising edge of the synchronization clock CK, the peripheral device 1 samples the data reception signal line DI of the peripheral device 1 (i.e., the data transmission signal line DO of the master), and converts the voltage signal value on the line 2080 millivolts back to the digital signal quantity 0xD with the ADC of the peripheral device 1. And finally, the received low 4-bit data and high 4-bit data are combined back to the original one-byte data 0xD5, so that the data transmission process of the master device for transmitting one byte 0xD5 to the peripheral device 1 is realized. If there is more data to be transmitted after this data transmission, the above-mentioned process can be repeated, and if the transmission process is to be ended, the master device pulls the chip select signal CS1 of the peripheral device 1 high, and the transmission process can be ended.
In the above transmission process, each synchronous clock cycle can transmit 4 bits of data, and two synchronous clocks are needed to complete data transmission of 8 bits, namely one byte, while a common serial communication mode is that each synchronous clock transmits 1 bit of data, and at least eight synchronous clock cycles are needed to complete data transmission of one byte.
If the transmission format information is determined to be 8 bits of data, i.e., one byte of data, to be transmitted to the outside of the data transmission Fang Yici based on the attribute information of the data transmission side and the attribute information of the data reception side, the transmission can be completed with only one synchronization clock. Since the value range that can be represented by the 8-bit data is 256 values of 0-255, the maximum voltage 2560 millivolts can be equally divided into 256 parts, that is, each part is 10 millivolts, so that the corresponding relation between the 8-bit data and the voltage signal can be obtained, that is, a=10×d (millivolts), where a is the voltage signal value corresponding to the data to be transmitted, the unit is millivolts, and D is the data to be transmitted. The voltage signal value corresponding to the target data 0xD5 is 2130 millivolt.
Fig. 5 is a schematic diagram of signal variation in another data transmission method according to the third embodiment of the present invention. As shown in fig. 5, at the beginning of the transmission, the master first pulls down the chip select signal CS1 of peripheral device 1, gating communication with peripheral device 1. The master device then sends the 8-bit data 0xD5 to the DAC, and the master device outputs the synchronous clock CK of the first falling edge, converts the data 0xD5 in the DAC into a voltage signal value 2130 millivolts, outputs the voltage signal value 2130 millivolts to the data transmission signal line DO and maintains the current electric signal value. When the master device outputs the first rising clock CK, the peripheral device 1 samples the data receiving signal line DI of the peripheral device 1 (i.e. the data transmitting signal line DO of the master device), and converts the voltage signal value 2130 millivolts on the line back to the digital signal quantity 0xD5 with the ADC of the peripheral device 1, i.e. the data transmission process of the master device transmitting one byte 0xD5 to the peripheral device 1 is realized. If there is more data to be transmitted after this data transmission, the above-mentioned process can be repeated, and if the transmission process is to be ended, the master device pulls the chip select signal CS1 of the peripheral device 1 high, and the transmission process can be ended.
In the above transmission process, 8 bits of data can be transmitted in each synchronous clock cycle, and one synchronous clock is needed to complete data transmission of 8 bits, namely one byte, whereas a common serial communication mode is that each synchronous clock transmits 1 bit of data, and at least eight synchronous clock cycles are needed to complete data transmission of one byte, in contrast, the transmission rate can be improved by 8 times by adopting the technical scheme in the embodiment of the invention.
According to the technical scheme, the data transmission rate can be improved by using a small number of buses, the connection between the devices is convenient, and the number of the ports occupied by the parallel interface is small compared with the number of the ports occupied by the parallel interface.
