spwm逆变器的电容电流和负载电压闭环控制 花了些时间调好的 给需要的人(spwm inverter capacitor current and load voltage closed-loop control took some time to those who need a good tune)

基于ADT75的c51数字温度读写以及IO口实现模拟i2c通信驱动(ADT75 based C51 digital temperature reading and writing as well as IO port to achieve analog I2C communication driver)

说明：  使用51单片机控制某芯片，实现AD数模转换的功能。(A chip is controlled by 51 single chip computer to realize the function of AD digital-to-analog conversion.)

led 动态显示与数据通信，采用单线单向传输，上位机将数据按通讯协议编码后向显示器送出，该程序为接收显示程序。(led dynamic display and data communications, using one-way one-way transmission, and host computer data communication protocol will be encoded to display sent, the procedure for receiving display program.)

说明：  PID控制pwm风扇，可吹小球，附带激光测距，可通过LCD显示(PID control PWM fan, can blow small ball, with laser ranging, can be displayed by LCD)

程序主要实现了无线模块nrf24l01传输温度的，功能。(Program achieved a major wireless module nrf24l01 transmission temperature function.)

Some code examples for NMEA gps and SIM800

说明：  7541数字高频头源程序，7541数字高频头源程序(7541 digital tuner source, 7541 the first digital high-frequency source)

采用stm8s003单片机，使用NTC传感器和数码管，编写的温度计，检测精度0.1c°(Using stm8s003 microcontroller, the use of NTC sensor and digital tube, the preparation of the thermometer, detection accuracy 0.1c °)
