功能： 1、作为主机通讯采集两路下位机数据并将此数据通过8255送出（十路水位值） 并计算水头送STC板 2、采集数据为BCD码制，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 在此系统中本机硬件地址要设为0-Features: 1, as the host of two-way communication acquisition of data-bit machine and send this data through 8255 (the road level 10 value) and calculate the head sent to STC board 2, for BCD code data collection system, the first converted into binary, and then deal with the conversion into BCD 3, communication using methods 3, multi-machine communications, address PC made 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 in this system to the local hardware address set to 0

1602的程序，写的很规则，希望对大家有帮助，是电脑里存了很久的，曾经自己写的-1602 procedures, the rules are written, in the hope that we help keep the computer for a long time, and have written their own

1.电子琴功能 用实验板上K1~K7作为电子琴的7个按键，每个按键对应一个音符要求当按下其中一个按键，就通过P2.5口输出对应频率信号使蜂鸣器发出特定音符声音。 2.乐曲演奏 若按下K8键，完成自动弹奏“送别”歌曲。 -1. Organ function of the experimental board K1 ~ K7 as the organ of the seven buttons, each button corresponds to a note of which require that when the press of a button, on the adoption of P2.5 port output frequency signal corresponding to a specific note to the buzzer sounds . 2. Music playing, if pressed K8 button to complete the auto-play " Farewell" songs.
