不错的拓普微3.5寸LCD显示屏驱动代码，可以参考(Good TOPWAY 3.5-inch LCD display driver code, you can refer to it)

51单片机的闪烁灯代码一，非常适合初学者的使用，在这分享给大家。(51 MCU flashing lights code, very suitable for beginners to use, in this share to everyone. )

用电脑串口控制单片机流水灯状态,用电脑串口控制单片机流水灯状态(Serial control with a computer chip light water status)

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.)
