| 摘 要： | 针对在噪声干扰比较大的工业环境下对RS-422通信的需求,该设计采用TMS320F2812作为主处理器,利用外部接口(XINTF)片内的两路SCI异步串口,并通过可编程逻辑器件EPM240T100C5N(CPLD)两片MAX3160连接,实现了上位机和下位机之间、下位机和下位机之间的RS-232通信、RS-422通信.

| Abstract: | In the industry-environment with strong noise,the RS-422 communication is used greatly.According to this requirement,TMS320F2812 is adopted as the main processor,and connected with two MAX3160 through EPM240T100C5N(CPLD) utilizing the XINTF and two inner SCI UART,to male the communication between PC and DSP or between DSP and DSP comes true in this design. |
