stm32_SPWM_DAC_ADC_DMA

io口模拟i2c，很好的代码，稍作修改，就可以在你的平台上使用了。(io port analog i2c, good code, slightly modified, you can use on your platform.)

基于STM32F407的超声波模块测距，增量式编码器（1/30减速比）实时测速，PWM输出控制直流单机，并通过OLED显示实时数据，同时也通过串口打印(Based on STM32F407 ultrasonic module ranging, incremental encoder (1/30 deceleration ratio) real-time speed measurement, PWM output control DC single machine, and display real-time data through OLED, but also through serial port printing.)

esp8266测试源码,测试STA和AP功能。并且对TCP,UDP测试（来自原子）。(Esp8266 test source code, testing STA and AP functions. And for TCP, UDP tests ( atoms).)

说明：  STM32F103的串口通信程序，需要在keil5上运行。(The serial communication program of STM32F103 needs to run on keil5.)

51单片机驱动74ls164程序 (51 Microprocessor 74ls164 program)

说明：  这是一个基于PIC的AD转换,希望对大家有用(AD FOR PIC...)

1602LCD液晶秒表，实现的C语言源程序(1602LCD LCD stopwatch to achieve the C language source code)
