3.3 Communication protocol

RS-422 method

Serial communication, in line with RS-422 interface standard;
Data update interval: 2.5ms, data transmission baud rate: 115.2kbps;
Data Format:

Data transmission format: Each frame of data is 11 bits, the first bit is the start bit (0), the 2nd to 9th bits are data bits, the 10th bit is the even parity bit, and the 11th bit is the stop bit;
Check mode: even check;
The gyroscope valid data is 32 bits (the highest bit is the sign bit, 0 is "+", 1 is "-"), and the temperature valid data is 21 bits (the highest bit is the sign bit, 0 is "+", 1 is "-");
Data packet format: Each transmission includes 10 bytes in total. The first byte is the frame header (80H); the second byte is the first byte data of the gyroscope (low byte), the third byte is the second byte data of the gyroscope, the fourth byte is the third byte data of the gyroscope, the fifth byte is the fourth byte data of the gyroscope, and the sixth byte is the fifth byte data of the gyroscope (high byte); the seventh byte is the check bit, which is the XOR value of the first five bytes (gyroscope data) in the data packet; the eighth byte is the low byte of the temperature data, the ninth byte is the middle byte of the temperature data, and the tenth byte is the high byte of the temperature data;Data storage method:
