STM32F1、F4电机PWM调速及PID速度闭环控制(PWM Speed Regulation and PID Speed Closed-loop Control of STM32F1 and F4 Motors)

用ADC0809做成的数字电压表，附带proteus仿真原理图和原程序。(ADC0809 made with digital voltage meter, incidental Proteus simulation schematic and the original procedure.)

说明：  使用STM32F103C8T6系统板，通过两个NRF24L01模块实现无线通信，将光电二极管驱动电路采集到的荧光强度值无线传输到上位机的串口软件显示出来。(Using stm32f103c8t6 system board, wireless communication is realized by two nRF24L01 modules, and the fluorescence intensity value collected by the photodiode driving circuit is wirelessly transmitted to the serial port software of the upper computer to display.)

野火开发板触摸屏主程序,涉及到的函数库在其官方库有(Wildfire main touch screen development board)

stm32F410X PCA例程，Stm32F410x很好的学习资料(Stm32F410X PCA routines, stm32F410X very good learning material )

该驱动程序库包含了I2C总线基本时序以及AT24C系列EEPROM的读写函数.还包含了常用数据格式变量的保存、读取函数。除了字节读写之外，还可以很方便的向EEPROM里写入和读出整型、浮点数、长整型格式的数据。(The driver library includes the basic timing of the I2C bus and EEPROM read and write functions AT24C series. Also includes a common data format for the variable save, reading function. In addition to reading and writing bytes, but also can easily write and read to the EEPROM in the integer, floating point, long integer format.)

在Proteus环境下使用LM311电压比较器进行比较和整流。LM311电压比较器设计运行在更宽的电源电压，从标准的±15V运算放大器到单5V电源用于逻辑集成电路。 (LM311 compare shaping, using Proteus LM311 voltage comparator designed to operate over a wider supply voltage: 15V op amps from a standard to a single 5V power supply for the logic IC)

基于51单片机的PT2314音频功放程序，可实现MIC和音频输入切换及音量音调控制，并用5110显示(Based on 51 single-chip audio amplifier PT2314 program can achieve MIC and audio input switching and volume tone control and display with 5110)
