3leds

说明：  使用TM1638驱动共阳数码管显示，Keil4工程(Using tm1638 to drive the display of common positive nixie tube)

说明：  此代码为stm32将外部flash如w25q32模拟成U盘，对内部数据进行读写操作，此工程已经验证通过，希望对大家用一定的帮助(This code is stm32, which simulates external flash such as w25q32 into a U disk to read and write internal data. This project has been verified and passed. I hope it will be of some help to you)

小车控制，蓝牙通信 温湿度传感器驱动 pm2.5传感器驱动(Car Control, Bluetooth Communication Temperature and Humidity Sensor Drive PM2.5 Sensor Drive)

日本北斗公司开发的usb鼠标源程序单片机为HITACHI--H8S2215(developed by usb mouse source for Hitachi microcontroller-- H8S2215)

说明：  利用TI公司生产的ARM款单片机MSP432实现硬件I2C，具有更加强大的性能(ARM chip microcomputer MSP432 produced by TI company is used to realize hardware I2C, which has more powerful performance)

不错的拓普微3.5寸LCD显示屏驱动代码，可以参考(Good TOPWAY 3.5-inch LCD display driver code, you can refer to it)

说明：  使用超声波模块测距，测距范围 10cm--1..2m(Using ultrasonic module to measure distance, ranging range is 10cm-1.2m.)

本实验将实现如下功能：本章我们在UCOSII里面创建3个任务：开始任务、LED0任务和LED1任务，开始任务用于创建其他（LED0和LED1）任务，之后挂起；LED0任务用于控制DS0的亮灭，DS0每秒钟亮80ms；LED1任务用于控制DS1的亮灭，DS1亮300ms，灭300ms，依次循环。(This experiment will achieve the following functions: in UCOSII, we create three tasks: start task, LED 0 task and LED 1 task, start task for creating other tasks (LED 0 and LED 1), then hang up; LED 0 task for controlling the brightness of DS0, DS0 80 ms per second; LED 1 task for controlling the brightness of DS1, DS1 300 ms. 300 ms, cycle in turn.)

89c51 单片机通过 PFC8591进行AD-DA转换。最后通过1602显示屏进行显示 (89C51 singlechip AD-DA conversion by PFC8591. To display the 1602 display)

用STM32模拟IIC主机，读取24c0x的内容。(Using STM32 simulation IIC host, read the contents of the 24 c0x.)
