摘要
TMS3 2 0 C5 4X高速 DSP芯片由于缺少 UART标准接口 ,与带 UART的外设直接进行异步通信比较困难。本文介绍了一种用软件模拟实现 UART方法 ,可以较好地解决这个问题。该方法无须额外硬件开销 ,实验表明 :简单方便 ,灵活可靠。
Because the TMS320C54X haven't UART port,it is difficulty to communicate directly between the external device with UART port and TMS320C54X.Now we introduce the implementation of a software UART on TMS320C54X which can solve the problem easily.Though this method needs no more hardware,it is simple flexible and reliable.
