用PIC单片机实现带音乐播放的电压表,最高实现3.3V的电压测试(PIC mcu)

iCan4017模块改进程序，语言Windows Visual C++(iCan4017 programme, Windows Visual C++.)

MCU图片解码，使用STM32对JPEG图片解码，(STM32 JPEG decoder code,)

一个电表行业专用的基于645规约的电表485通讯抄表程序，可以进行485总线抄表，645规约测试。程序技术要点就是规约数据传输协议的处理，如向电表发送数据时的控制码和数据长度、发送的数据部分(数据标识 + 密码 + 数据)、应答帧长度、结束标志等通讯协议的处理值得大家学习。(A meter-based industry-specific statute 645 meter 485 meter-reading procedure can be carried out 485 meter, 645 Statute of the test. Procedures for the technical elements of the statute is to deal with data transmission protocols, such as sending data to the meter when the control code and data length, send the data section (data logo+ Password+ Data), response frame length, marks the end of the treatment protocol, etc. everyone deserves to learn.)
