基于stm32的Can总线双机通讯上位机源码，有命令模式及数据通信模式，数据通过串口打印到PC端串口调试助手-The Can-bus based stm32-machine communication PC source, there is command mode and data communication mode, data is printed to the PC via the serial port debugging a

做主机接收时，不能和发送共用一个函数。该程序是基于stm32的双机通信程序。一定要理解好主机和从机的作用，做主机时会控制通信的时钟，从机是不能产生时钟的。如果从机要发送数据，那可以在主机发送数据 的时钟上发送数据。(You cannot share a function with the host when you host the receiver. The program is based on STM32 dual compute

基于STM32的双机全双工SPI主从通信程序，包括主机程序和从机程序。(STM32 dual full duplex SPI master-slave communication based program, including the host program and the program from the machine.)
