具有排错功能的TMS320F2812DSP与PC机的串口通信设计

摘要

根据串口通信规则设计了TMS320F2812DSP与PC机之间的串口通信协议，采用SCI模块的FIFO堆栈模式进行接收数据操作，实现数据的实时更新及数据接收过程中的排错功能，保证了数据的实时性和准确性。%The SCI communication protocol on TMS320F2812DSP and PC was designed according to the protocol of serial port communication. To receive data by using FIFO stack mode of SCI module, the function of data real time updating and trouble shooting was realized, and the instantaneity and veracity of data were ensured.
