说明：  红外线程序（使用C语言编写）（使用定时器作为解码）(红外线程序（使用C语言编写）)

宽频放大器,有以下功能: 预置增益,增益加/减,显示输出电压有效值,自动增益 显示有效值. 增益输入及加减 自动增益没有实现(Wideband amplifier has the following functions: Preset gain, gain plus/minus, the display output voltage RMS, automatic gain display rms. AGC gain input and subtraction is not implemented)

一个基于NXP公司的LPC1788芯片开发的程序，该程序是一个下拉式菜单模板，利用了面向对象程序设计理念，非常容易扩充菜单内容。(Based on NXP s LPC1788 chip development a program, which is a drop-down menu template, use of object-oriented programming concepts, very easy to expand the menu contents.)

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.)

用TI单片机MSP430系列写的CRC检验程序，C语言(Using TI single-chip MSP430 series written by CRC testing procedures, C language)

基于C51单片机的4*4矩阵键盘扫描。有仿真和程序，数码管显示，可以用于学习矩阵键盘扫描的基础知识。并可以进行扩展。(Based on the C51 microcontroller 4* 4 matrix keyboard scanning. There simulation and procedures, digital display, can be used to learn the basics of the keyboard scan matrix. And can be extended.)

说明：  使用P3.2外部中断下降沿触发， 对NEC红外编码方案进行解码。 单片机晶振12M, 22pf匹配电容 测试遥控器为淘宝购买， 淘宝输入 ‘红外遥控器’ 即可， 不到2元一个。 单片机用的是 STC 的 12C5A60S2， 使用串口下载烧录程序。 因为使用的12M晶振， 不是11.0592，所以使用单片机内部的专用波特率发生器， 最高9600bps，再高就乱码误码比较大了。 红外接收电路1838T 3脚一体化， 使用数据手册里的推荐电路， 自行百度。(NEC infrared decoder program based on STC MCU using C language. MCU model: STC12C5A60S2 CRYSTAL: 12 M INFRARED RECEIVER MODEL: 1838T)

避障小车红外避障，超声波避障，寻光外加寻迹(Obstacle Avoidance Car Infrared Obstacle Avoidance, Ultrasound Obstacle Avoidance, Light Seeking and External Tracking)

基于ARM Cortex-M4F(TM4C123)单片机 ，编程控制TM4C123微控制器的RTC 模块，实现一个简易的数字时钟，具有多种功能 ?【功能】 ?（1）UART输出当前时间信息，UART可设置日期和时间，设置方法自定； ?（2）可通过UART 设置/查询闹钟，定闹时间到，从UART输出提醒； ?（3）在液晶屏上显示日期和时间信息（中文）； ?（4）可使用实验板上的K1-K4按键修改日期和时间，设置方法自定； ?注：该题依赖于“3”，需先完成“3”才可做该题 ?（5）农历功能，农历自动跟踪阳历的变化； ?（6）24节气功能(Based on ARM Cortex-M4F (TM4C123) MCU, the RTC module of TM4C123 microcontroller is programmed and controlled to realize a simple digital clock, which has many functions. (function) (1) UART output the current time information, UART can set the date and time, set the method to set itself. (2) the alarm clock can be set / inquired by UART, and the time is up until UART is output. (3) display date and time information on LCD screen (Chinese); (4) you can use the K1-K4 button on the experiment board to change the date and time, and set the method to set it. Note: the question depends on "3", and it is necessary to finish "3" first. (5) the function of the lunar calendar, and the lunar calendar automatically tracks the changes of the solar calendar. (6) the function of 24 throttle)
