功能： 1、作为下位机采集8255数据并将此数据通过通讯送出， 2、采集数据为BCD，先转换成二进制，处理后再转换成BCD 3、通讯采用方式3，多机通讯，上位机发地址时TB8=1，其他TB8=0 下位机SM2=1，RB8=1时产生中断后使SM2=0收发数据，结束后SM2=1-Features: 1, as under the 8255-bit machine data collection and communications sent through this data, 2, collected data for the BCD, first converted into binary, and then converted to deal with BCD 3, communication using methods 3, multi-machine communication, PC-fat address TB8 = 1, other TB8 = 0 under the digital machine SM2 = 1, RB8 = 1 when the failure to make SM2 = 0 to send and receive data, after the end of SM2 = 1

本人设计的用802051实现的键盘程序的识别代码。系统采用定时查询，防抖。如果监测到你一个代码，系统将键盘码输出。然后给我你个中断，用于提示中心机，读取键码。支持长按。-I designed keyboard with 802,051 procedures to achieve the identification code. System uses a regular query, Anti-Shake. If the monitoring to you a code, the system will output the keyboard code. And then give me interrupt you for the prompt Center machine, read the key code. Support the long press.
