Detailed Description
The standard SPI (Serial Peripheral Interface) protocol requires software to configure communication modes of the two parties in advance when the master and slave devices communicate, and communication errors can be caused if the communication modes configured by the two parties do not correspond. The software configuration mode adopted at present has slower configuration speed.
Based on the above problems, the communication mode configuration method and device for the SPI protocol master-slave device control the corresponding slave device through the chip selection pin and the chip selection signal line of the master device, realize the time sequence of data between the master device and the slave device through the clock signal of the clock line, ensure the accuracy and the synchronism of the data, and send command streams to configure the communication mode of the slave device through the MOSI line and the MISO line.
It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
Fig. 1 is a flow chart of a communication mode configuration method of an SPI protocol master-slave device provided in an embodiment of the present application, referring to fig. 1, a master device may be correspondingly connected to at least one slave device, and when the master device configures a communication mode for a certain slave device, the method includes:
s101, if the configuration mode of the slave device is selected to be hardware configuration, the master device pulls up the chip select signal.
For example, when the slave device configuration mode can also select the software mode to configure the slave device, if the slave device configuration mode is selected to be the software configuration, the software configuration is performed on the slave device according to the standard SPI protocol.
Specifically, the master device pulls up the chip select signal refers to pulling up the chip select signal sent to the slave device by the master device through the chip select pin. A chip selection signal line is connected between the chip selection pin of the master device and the chip selection pin of the slave device.
S102, generating a command stream according to a main device communication mode configured by software, transmitting the command stream to a slave device by the main device through an MOSI line, generating a clock signal through a clock pin so that the slave device configures according to the command stream, and transmitting a completion mark to the main device through a MISO line after the configuration is completed.
Specifically, the MOSI line between the master device and the slave device is used for the master device to send signals to the slave device, and the MISO line is used for the slave device to send signals to the master device.
In particular, a clock signal is a periodic signal whose rising and falling edges can be used to synchronize and drive operations in a circuit. The clock pins are typically provided by a master device (e.g., a microprocessor or clock generator) and may be connected to clock inputs of various slave devices (e.g., registers, counters, memory, etc.). By means of the clock signal provided by the clock pin, the individual components in the overall circuit can operate and data transfer in coordination.
And S103, the master device finishes generating a clock signal and pulling down a chip select signal according to the received completion mark so as to communicate with the slave device.
The slave device sends a completion flag to the master device through the MISO line, and when the master device receives the completion flag, the master device indicates that the communication mode of the slave device is configured, and the master device and the slave device can communicate.
According to the above steps S101-S103, the present application may control the corresponding slave device through the chip selection pin and the chip selection signal line of the master device (pull up the chip selection signal, the master device may perform communication mode configuration on the slave device, after completing the configuration, pull down the chip selection signal, the master device and the slave device may perform communication), realize the timing sequence of data between the master device and the slave device through the clock signal of the clock line, ensure the accuracy and the synchronism of the data, and send command streams to configure the communication mode of the slave device through the MOSI line and the MISO line, so that the communication mode of the slave device can be completed based on the hardware configuration pin or the connection line between the master device and the slave device, the data transmission is reliable and the transmission speed is fast, and the configuration speed of the communication mode of the slave device is improved.
In this embodiment of the present application, step S101 described in fig. 1 may further include, before the master device pulls up the chip select signal if the slave device configuration mode is a hardware configuration: the software configures the master device communication mode. Specifically, the configuration of the communication mode is performed on the master device according to the SPI protocol.
Correspondingly, in step S101, a command stream is generated according to a main device communication mode configured by software, and a specific implementation manner may be:
identifying a communication mode of the main equipment configured by the software to obtain an identification result;
and generating a command stream according to the identification result.
In one possible implementation, the command stream includes a configuration for polarity, phase, transmit/accept, and full/half duplex.
In another possible implementation, the master device and slave device count down by a rising edge of a clock signal, and a falling edge count, before the pull-down chip select signal.
Specifically, the rising edge number refers to that when the rising edge of the clock signal arrives, the data of the transmission signal is transmitted to the receiving party so that the receiving party performs data acquisition. The number of falling edge acquisition means that when the falling edge of the clock signal arrives, the receiving party acquires the transmitted data and stores or carries out subsequent processing. The rising edge count and the falling edge count can ensure that data is correctly transmitted and collected at the stable moment of a clock signal. The rising and falling edges of the clock signal provide an explicit time reference enabling the sender and receiver to perform data transmission and acquisition at synchronized moments.
For example, referring to a timing diagram of one hardware configuration shown in fig. 2, when the chip select signal is pulled up, the master device may sequentially transmit a plurality of configuration data (for example, may correspond to a polarity of transmission at a rising edge of a 3 rd period, a transmission/reception at a rising edge of a 4 th period, a transmission full/half duplex at a rising edge of a 5 th period, and a transmission/reception at a rising edge of a 6 th period) in a command stream at a rising edge of a plurality of periods (for example, may correspond to a polarity of transmission at a falling edge of a 3 rd period, a transmission phase of transmission at a falling edge of a 4 th period, a transmission/reception at a falling edge of a 5 th period, and a transmission full/half duplex at a falling edge of a 6 th period) in succession in a clock signal through the MOSI line, so that the slave device receives the configuration data transmitted at the rising edge from the falling edge corresponding to each rising edge in turn (specifically, may correspond to the transmission polarity at the falling edge of the 3 rd period, for example), and performs the corresponding configuration. Then, when the slave device completes the configuration of the communication mode, the slave device transmits a completion flag to the master device through the MISO line (for example, see fig. 2, after completing the configuration of the command stream in the 6 th cycle, the slave device transmits a completion signal to the master device through the MISO line in the 8 th cycle). After receiving the completion flag through the MISO line, the master device pulls down the chip select signal sent to the slave device through the chip select pin. The master device and the slave device can perform data interaction communication.
Illustratively, the completion flag may be 2' b10.
Specifically, 2'b10 is a binary representation in which 2' b represents a value represented using two bits (bits) and 10 represents a value of a binary number. In 2' b10, the leftmost bit represents the most significant bit and the rightmost bit represents the least significant bit. Thus, 2' b10 represents a binary number, with the highest order being 1 and the lowest order being 0.
The communication mode method of the master-slave device of the SPI protocol provided by the embodiment of the present application is described above, and an exemplary description is made below of the communication mode method of the master-slave device of the SPI protocol in combination with a specific application scenario.
Referring to fig. 3, a schematic application flow diagram of a communication mode of an SPI protocol master-slave device is shown. An application method of communication modes of SPI protocol master-slave equipment comprises the following steps:

S303, identifying the communication mode of the main equipment configured by the software, and obtaining an identification result.
S304, generating a command stream according to the identification result, generating a clock signal and transmitting the command stream to the slave device through the MOSI line.
S305, after the slave device completes configuration according to the command stream, a completion mark is sent to the master device through the MISO line.
Specifically, referring to a schematic diagram of hardware configuration of an SPI master device and a slave device and command flow thereof shown in fig. 4, when a chip select signal is invalid, the master device needs to configure a communication mode for the slave device, and steps S302 to S305 described above may be performed, a master device generates a command flow according to the master device communication mode configured by software, then the master device generates a clock signal through a clock pin (SCLK), and sends the command flow to the slave device through a MOSI line, and the slave device sends a completion flag to the master device through a MISO line after receiving and configuring the command flow.
S306, if the configuration mode of the slave equipment is selected to be software configuration, completing the configuration of the slave equipment according to a standard SPI protocol;
s307, pull down the chip select signal, the master device and the slave device may communicate.
Specifically, referring to fig. 5, which shows a hardware configuration and communication schematic diagram of an SPI master device and a slave device, after the configuration of the communication mode of the SPI master device and the slave device is completed, the master device sends a clock signal when a chip select signal is valid, and then data can be transmitted between the master device and the slave device through a MISO line and a MOSI line.
As can be seen from the above steps S301 to S307, the master device of the present application may adopt a hardware configuration mode to configure the communication mode for the slave device (steps S302 to S305), or may adopt a software mode to configure the communication mode for the slave device through a protocol (step S306).
