摘要
在工业现场控制领域,干扰因素的存在使得单片机系统通信信息检测成为该系统的重要环节,本文针对某些片内没有硬件奇偶校验电路的单片机系统,提出软件实现纵横奇偶校验的方法,讨论具体实现要注意的一些问题,并给出了相应的源代码.
In the control domain of industry scene,it is important to examine the single-chip computer＇s communication information because of existence of disturbance factors.in view of some single-chip computers do not have the hardware parity check circuit,this article proposes the method to realize vertically and horizontally parity check by software, and discusses some questions that to be paid attention as concrete realization,in the last gives the source code.
