FTCP动态库

串口与pc机通讯，51单片机例程，只需要修改io口即可实现。(Serial communication with pc, 51 MCU routine, you only need to modify the io port can be realized.)

SIM800C升级工具,二次开发工具，省成本的特别好用用的方案(SIM800C upgrade tool)

利用单片机IO口模拟UART程序,系统用了一个定时器和一个外部中断,外部中断主要是用来检测串口起始位的到来。(IO mouth simulation UART program, microcontroller system with a timer and an external interrupt, external interrupt is mainly used to detect the arrival of the start bit serial port.)

基于单片机的电子称实验 希望大家能够喜欢 用的是51系列单片机(Microcontroller-based electronics experiments hope you will enjoy with the 51 series)

采用4路红外对管进行循迹，电机控制小车运动。(Four infrared channels are used to track the tube, and the motor controls the motion of the car.)

这是一个基于THEVENIN的锂电池模型，能够观察到SOC和OCV。(This is a DCDC chopper, and is isolated and can be converted to low-voltage DC high-voltage direct current and voltage controlled to achieve, can be used for battery charging and discharging.)
