对一组数进行计算，产生两个字节的CRC校验结果的程序

这是我给一个做射频卡的公司做的小程序，主要是将数据同时写入PRR8031芯片和数据库，包括一些数据类型转换、生成序列号等内容-This is what I do for a radio card companies do small procedures, the data is also written into the PRR8031 chips, and databases, including some data type conversion, such as serial numbers generated content

自己编写的关于火车列尾风压控制的程序,涉及串口,数据库等相关内容-I have written out on the train tail wind pressure control procedures, involving serial, database and other related content

一个单片机读写fm24c256的c51源程序-a microcontroller to read and write fm24c256 the source decoder

自编的串口通信程序，支持一些简单命令-self serial communication program to support some simple orders

串口控制程序一般分为查询和中断两者方式。查询方式适用于简单的应用，简单可靠，但是缺点是需要占用处理器资源，在发送或者接收数据的时候不能做其它的事情，处理器利用率低。中断方式下，在发送或者接受数据的时候处理器还可以做其它的工作，效率较高。-Serial control procedures will generally be divided into two way query and interruption. Query applied to simple applications, simple and reliable, but the drawback is the need to occupy processor resources to send or receive data at the time should not make other things, the processor utilization rate. Interrupt mode, the send or accept data when the processor can do other work, more efficient.
