HRTS

说明：  图像处理程序,单片机嵌入式,FFT算法(Image processing procedures, single-chip embedded, FFT algorithm)

基于MSP430G2553来实现串口通讯，可以用上位机和下位机进行通讯(Based MSP430G2553 to achieve serial communication, you can use upper and lower machine communication)

This is the source code of the driver of the two wire serial comunication (i2c) for PIC4 microcontroller.

基于STM32F103的智能充电器，PID调节恒压恒流输出，具有温度补偿，过欠压，过欠流保护功能，可直接用于开发。注释比较详细。(STM32F103-based smart charger, PID regulation constant voltage constant current output, with temperature compensation, over-voltage, over-current protection owed can be directly used for development. More detailed notes.)

说明：  STM8S208单片机 can口驱动程序(STM8S208 can port driver)

键盘和LCD显示。Proteus调试通过！(Keyboard and LCD display. Proteus debugging through!)

avr ATmega128 PWM输出OCR1A=0x40 //OC1A 输出 25 占空比 OCR1B=0x80 //OC1B 输出 50 占空比 OCR1C=0xc0 //OC1C 输出 75 占空比(avr ATmega128 PWM)

说明：  通过ESP32,实现OTA更新stm32的程序。。。。(Update program through OTA)

DAC8571通过iic协议和msp430通信(DAC8571 communicates with MSP430 through IIC protocol)

AT89C2051时钟程序，有注释，开心学习！(AT89C2051Clockprocess)
