The data burning method of the processor can be used for receiving the first byte data in the buffer area through the acquired serial port; acquiring burning signal data; checking the first byte data according to the burning signal data; based on the verification result, judging whether the data in the serial port receiving buffer area is the burning signal data or not; and if the data in the serial port receiving buffer area is the burning signal data, controlling the processor to reset and executing data burning. The programming request signal is identified by using the algorithm, so that the processor is automatically reset, the switching between the bootstrap program and the application program is realized, the programming operation flow is simplified, the programming efficiency is improved, and the user experience is improved.
As shown in fig. 2, the data burning method of the processor includes steps S101 to S105.
S101, acquiring first byte data in a serial port receiving buffer area.
The serial port receiving buffer area is a buffer space for receiving data in the serial port.
It should be noted that, the serial port is a serial interface, also called a serial communication interface or a serial communication interface, and refers to a serial communication interface that sequentially transmits data bit by bit, and is characterized in that the serial port transmits and receives bytes according to bits (bits). When used in serial ports, the serial port generally includes two buffers, namely a transmit buffer and a receive buffer. When transmitting data, the data is stored in a transmission buffer area and then transmitted through a serial port; when receiving data, the received data is stored in a receiving buffer area, and then is read. Due to the limitation of the serial communication mode, a buffer space is needed for buffering the data to ensure the integrity of the data.
The first byte of data is one byte of data in the serial port receive buffer, and it is understood that the data location of the first byte of data is at the first bit of the sequential transfer in the serial port receive buffer.
Specifically, one byte of data in the serial port receiving buffer is obtained as first byte data for verification with the recording signal data.
In some embodiments, the acquiring the first byte of data in the serial port receiving buffer includes: receiving signals of the serial port receiving buffer area through an interrupt receiving function; if the interrupt receiving function receives an interrupt signal sent by the serial port receiving buffer zone, calling an interrupt processing function, wherein the interrupt signal is a signal generated when the serial port receiving buffer zone is not empty; and accessing the serial port receiving buffer area through the interrupt processing function to acquire the first byte data.
Specifically, when data exists in the serial port receiving buffer, an interrupt signal is generated, and when the interrupt receiving function receives the interrupt signal, the interrupt processing function is mobilized to access the serial port receiving buffer, so that first byte data in the serial port receiving buffer is obtained.
It should be appreciated that since the interrupt handling function only obtains one byte of data at a time, the serial receive buffer remains non-empty until the data in the serial receive buffer is completely obtained by the interrupt handling function, and an interrupt signal is generated every time a period of time.
In some embodiments, the burning method of the processor further includes: the first byte data is stored in a first variable.
Specifically, after the interrupt function obtains the first byte data, the data is temporarily stored in the first variable, so as to prepare for the subsequent identification of whether the first byte data is the recording signal data.
S102, acquiring burning signal data.
Specifically, in order to check whether the data in the serial port receiving buffer is the recording signal data, it is necessary to obtain the data corresponding to the recording signal sent by the recording tool, as the recording signal data, the data may be fixed and composed of 8 bytes of data, as shown in fig. 3, and the data is the recording signal data, specifically including "0×05, 0×0A, 0×01, 0×00, 0×08, 0×27".
S103, checking the first byte data according to the burning signal data.
Specifically, in order to identify the recording signal, the processor is further reset, and the first byte data is verified according to the data of the recording signal data.
In some embodiments, in order to obtain an accurate verification result, before the verifying the first byte data according to the recording signal data, the method further includes: acquiring a second variable, wherein the second variable is used for recording the number of continuous pass of byte verification; and determining second byte data in the burning signal data based on the second variable, wherein the second byte data is used for checking the first byte data.
The second byte data is one byte data in the burning signal data.
It should be understood that, since the recording signal data is composed of 8 byte data, and the interrupt processing function only obtains one byte data at a time, and only 8 consecutive passes of the check can confirm that the data in the serial port receiving buffer is the recording signal data, the second variable is required to record the number of times of the check passing continuously, thereby resetting the control process when 8 consecutive passes of the check are passed. Wherein the second byte data used to check the first byte data may also be different depending on the number of consecutive passes of the check. Therefore, the second byte data corresponding to the first byte data to be checked currently needs to be determined according to the value of the second variable, so as to obtain an accurate checking result.
For example, when the check is performed twice, the second variable is 2, as shown in fig. 3, and the corresponding second byte data is "0×0a", and if the first byte data matches the second byte data, the check is performed three times, and the value of the second variable is 3, as shown in fig. 3, the corresponding second byte data is "0×0a", and at this time, the second byte data used for checking the first byte data in the two checks is the same. For another example, when the check is performed three times in succession, the second variable is 3, as shown in fig. 3, the corresponding second byte data is "0×0a", and if the first byte data matches the second byte data, the check is performed four times in succession, the value of the second variable is 4, as shown in fig. 3, the corresponding second byte data is "0×01", and at this time, the second byte data used for checking the first byte data in the two checks are not identical.
In some embodiments, to accurately verify the first byte data, the determining the second byte data within the burn signal data based on the second variable includes: acquiring the value of the second variable; increasing the value of the second variable by 1 to obtain sequential numbers; and acquiring byte data at a corresponding position in the burning signal based on the sequence number to serve as the second byte data.
Specifically, the value of the second variable represents the number of continuous byte verification passing, and as the value of the second variable increases, the position of the second byte data used for verifying the first byte data in the recording signal data also changes, and the value increase 1 of the second variable is the sequential number of the bytes of the second byte data in the recording signal data, and the byte data in the corresponding position in the recording signal is searched according to the sequential number and is used as the second byte data.
For example, when the value of the second variable is 1, the second verification is performed after the first verification, and the value of the second variable is increased by 1, so as to obtain that the sequential number of the bytes of the second byte data in the recording signal data is 2, as shown in fig. 3, the byte data with the sequential number of 2 in the recording signal data is "0×05", and the second byte data is "0×05".
In some embodiments, the verifying the first byte data according to the programming signal data includes: if the first byte data is matched with the second byte data, checking is passed, and the value of the second variable is increased by 1; if the first byte data is not matched with the second byte data, checking is failed, and the value of the second variable is reset to 0.
Specifically, if the first byte data is the same as the second byte data, the matching is performed, the verification is passed, the value of the second variable is increased by 1, if the first byte data is different from the second byte data, the matching is not performed, the verification is not passed, and the value of the second variable is reset to 0.
It should be appreciated that since the second variable is used to record the number of consecutive passes of the check, when the first byte data does not match the second byte data, i.e., the requirement for consecutive passes of the check is no longer met, the value of the second variable is reset to 0.
For example, when the second variable is 1, the second check is performed now after the first check, and the second byte data is "0×05", and if the first byte data is also "0×05", the first byte data is identical to the second byte data, and the first byte data matches the second byte data, the check is passed, the value of the second variable is increased by 1, and the value of the second variable becomes 2.
For another example, when the second variable is 1, the second check is performed now after the first check, and the second byte data is "0×05", and if the first byte data is "0×0A" and is different from the second byte data, the first byte data and the second byte data do not match, the check is failed, and the value of the second variable is reset to 0.
And S104, judging whether the data in the serial port receiving buffer area is the burning signal data or not based on the verification result.
Specifically, the first byte data is checked according to the recording signal data, when the first byte data is matched with the recording signal data, the bytes are matched with the recording signal, and the numerical value of the second variable meets the preset condition, the data in the serial port receiving buffer area is the recording signal data; otherwise, the data in the serial port receiving buffer area is not the burning signal data.
In some embodiments, the determining whether the data in the serial port receiving buffer is the recording signal data based on the verification result includes: when the value of the second variable is equal to 8, the data in the serial port receiving buffer area is the burning signal data.
Specifically, the data in the serial port receiving buffer area is checked with the burning signal data for multiple times, and only when the data passes the check for 8 times continuously, the data in the serial port receiving buffer area can be confirmed to be the burning signal data. Because the second variable is used for recording the continuous passing times of the verification, if the value of the second variable is equal to 8, the continuous 8 times of the verification are passed, and the data in the serial port receiving buffer area can be determined to be the burning signal data; if the value of the second variable is less than 8 and the serial port receiving buffer area does not generate the interrupt signal any more, the data in the serial port receiving buffer area is not the burning signal data. If the value of the second variable is smaller than 8 and the serial port receiving buffer area continues to generate the interrupt signal, the recording signal data is not checked at present, and the checking is continued.
It should be understood that, the preset condition that the verification result meets may be determined according to the accuracy requirement of the user on the verification, and when the value of the second variable is equal to 8, determining that the data in the serial port receiving buffer area is the recording signal data is only one embodiment. Because the burning tool does not receive the signal ready for burning within the preset time, the signal ready for burning is transmitted to the development board again through the serial port, and in order to improve the accuracy of verification, the preset condition can be set to be that the value of the second variable is equal to 8 for a plurality of times within the preset time period, which is not limited herein.
S105, if the data in the serial port receiving buffer area is the burning signal data, the processor is controlled to reset, and data burning is executed.
Specifically, if the data in the serial port receiving buffer area is the recording signal data, it is determined that the recording tool sends the recording signal, and the processor is controlled to reset. At this time, the guiding program operated by the development board can receive the recording signal sent by the recording tool, and send the signal ready for recording to the recording tool through the serial port, after the recording tool receives the signal, the application program data packet is sent to the development board, and the guiding program starts to perform data recording work.
In some embodiments, the controlling the processor reset comprises: calling a reset function to reset the processor; and switching the running program from the application program to the bootstrap program based on the reset operation.
Specifically, the RESET function is called to RESET the processor, so that the RESET button on the development board is manually touched by a user to RESET the processor is replaced, the burning operation flow is simplified, the burning efficiency is improved, and meanwhile, the user experience is improved. After the reset operation, the application program gives the operation permission to the guide program, and the guide program sends a signal ready for recording to the recording tool through the serial port, so that the recording work can be started.
Referring to fig. 4, fig. 4 is a flowchart of another data recording method of a processor according to an embodiment of the present disclosure.
In some embodiments, since the interrupt processing function can only acquire one byte of data at a time, the identification of the recording signal data requires checking the data in the serial port receiving buffer with the recording signal data multiple times, and the multiple checking flow is shown in fig. 4.
The method comprises the steps that firstly, an interrupt processing function is called to obtain first byte data based on an interrupt signal sent by a serial port receiving buffer area; step two, judging whether the first byte data is matched with the corresponding second byte data, and returning to the step one if the first byte data is not matched with the corresponding second byte data; and thirdly, if the values are matched, judging the values of the second variables, if the values of the second variables are equal to 8, resetting the processor, and if the values of the second variables are not equal to 8, returning to the first step.
For example, based on an interrupt signal sent by a serial port receiving buffer, calling an interrupt processing function to acquire first byte data; judging whether the first byte data is matched with the corresponding second byte data, if the first byte data is not matched with the corresponding second byte data, resetting the value of the second variable to 0; returning to the first step, waiting to receive the interrupt signal sent by the serial port receiving buffer again; when the serial port receiving buffer area is received again and an interrupt signal is sent out, an interrupt processing function is called to acquire new first byte data; and judging whether the new first byte data is matched with the corresponding second byte data.
It should be understood that, after the new first byte data is obtained, since the second variable is reset to 0 at this time, the sequence data of the new first byte data and the corresponding second byte data is 1, and at this time, the first byte of the recording signal data is recognized again, as shown in fig. 3, and at this time, the corresponding second byte data is "0×05".
For example, based on an interrupt signal sent by a serial port receiving buffer, calling an interrupt processing function to acquire first byte data; judging whether the first byte data is matched with the corresponding second byte data, and if the first byte data is matched with the corresponding second byte data, adding 1 to the value of the second variable; judging whether the value of the second variable is equal to 8; if the value of the second variable is not equal to 8, returning to the first step, and waiting for the serial port receiving buffer area to send out an interrupt signal again; when the serial port receiving buffer area is received again and an interrupt signal is sent out, an interrupt processing function is called to acquire new first byte data; and judging whether the new first byte data is matched with the corresponding second byte data.
It should be appreciated that as the value of the second variable increases by 1, the progress of verification of the recording signal data increases. For example, when the value of the second variable is 3, as shown in fig. 3, the corresponding second byte data is "0×0a", and if the first byte data matches the second byte data, the value of the second variable is increased by 1, and the value of the second variable is 4, as shown in fig. 3, the corresponding second byte data is "0×01".
In some embodiments, the first byte data is obtained, it is determined whether the first byte data matches the corresponding second byte data, if the first byte data matches the corresponding second byte data, the value of the second variable is added with 1, at this time, it is determined whether the value of the second variable is equal to 8, if the value of the second variable is equal to 8, the verification is continuously passed for 8 times, it is determined that the data in the serial port receiving buffer is the recording signal data, and the processor is reset.
It should be understood that this process is repeated until the value of the second variable is equal to 8, and the first byte data in the serial port receiving buffer is acquired and checked multiple times, until the value of the second variable is equal to 8, the processor is reset, and the switching between the boot program and the application program is implemented. The accuracy of the burning signal identification is improved, the burning operation flow is simplified, the burning efficiency is improved, and the user experience is improved.
