9-ADC

基于单片机msp430 的高度测量 （超声波测距）(Height measurement (Ultrasonic Ranging) is based on SCM msp430)

STM32F405RGT6 的CAN1和CAN2相互通信，一个发送，一个接收，采用HAL固件库(STM32F405RGT6 of CAN1 and CAN2 communicate with each other, a sending a receiving using HAL firmware library)

串口0通信-查询方式实验向串口发送子节数据，并等待数据发送完成，使用查询方式(Serial 0 communication- ways to experiment sub-section to the serial port to send data and wait for the data transmission is complete, use the query mode)

正点原子Mini板实验十七：DAC实验，为新手准备的基础源码，基于C语言，芯片为STM32F103RC(Atom Mini board experiment seventeen: DAC experiment, for beginners to prepare the basic source code, based on C language, chip for STM32F103RC)

基于stm32的定时器中断应用，可产生相位差为90度的两路周期性脉冲，可用于模拟正交编码器脉冲(Stm32 timer interrupt based applications can generate a phase difference of 90 degrees two periodic pulse, can be used for analog quadrature encoder pulse)

I30 gasoline instrument panel color LED backlight module

主要反映了LCD液晶显示器的一些显示原理以及它的一些参数问题 (Mainly reflects the LCD monitor display principle and some parameters of the problem)

说明：  基于点阵屏的51单片机贪吃蛇小游戏，附带多种功能。非keil工程，使用codeblocks+sdcc编译，代码与keil工程有些许不同。(Based on the dot matrix screen 51 MCU Snake game, with a variety of functions. For non keil projects, code blocks + Sdcc are used to compile. The code is slightly different from keil projects.)

绿灯亮时，准许车辆通行，黄灯闪烁时，已越过停止线的车辆可以继续通行；没有通过的应该减速慢行到停车线前停止并等待，红灯亮时，禁止车辆通行。给行人看的叫人行横道灯，通常指由红、绿（绿为蓝绿）二种颜色灯组成用来指挥交通通行的信号灯，红灯停，绿灯行。(When the green light is on, the vehicle is allowed to pass. When the yellow light is flashing, the vehicles that have crossed the stop line can continue to pass.You should slow down to stop and wait at the stop line. No traffic is allowed when the red light is on.Pedestrian crossing lights for pedestrians, usually denoted by red, green (green, blue, green), two color lamps used to direct traffic signals, stop at red lights and green.)
