说明：  上海移远M72D模块驱动程序，已在stm32芯片实现运行，运行稳定可靠，有以下几大优点：代码具备可移植性、可靠性、可扩展性、防阻塞等，主要分为两大部分1指令的执行部分，2操作逻辑部分
(Shanghai Moyuan M72D module driver, which has been implemented on STM32 chip, runs stably and reliably. It has the following advantages: the code has portability, reliability, scalability, anti-blocking and so on. It is mainly divided into two parts: the execution part of one instruction and the operation logic part.)
