In the application of single chip microcomputer,the common communication protocols include CAN communication,I2C,UART,SPI,Lin,etc.Especially,communication protocols are required to realize information exchange and resource sharing between single chip microcomputer and single chip microcomputer,and between single chip microcomputer and peripheral modules.This paper takes SPI communication as an example to illustrate the efficiency and stability of communication between two MCUs. The current design SPI transmission rate is 1 Mb/s,and the test results show that the bit error rate can be kept at 0 under high and low temperature environments (-40 to 80 ℃).It can be used in automotive electronics or household electronic products.
