说明：  单片机上电以后LCD屏上显示欢迎回家， 先验证指纹再验证密码 ，同时验证成功开锁 指纹和密码分别可以验证3次 3次都错蜂鸣器响 ，按下manage键进入管理员模式 可以修改密码 删减指纹，指纹用开关量表示(After the microcontroller is powered on, the LCD screen shows welcome home. First verify the fingerprint and then verify the password. At the same time, verify the successful unlocking fingerprint and password can verify that the buzzer rings three times and three times respectively. Press the management key to enter the administrator mode to modify the password and delete the fingerprint. The fingerprint is expressed by the switch.)

说明：  用12864加STC12C5A60S2做的GPS解析(GPS Analysis with 12864 and STC12C5A60S2)

FM1188驱动程序（回音消除处理芯片），C语言编写(FM1188 driver (echo cancellation processing chip), written in C language)

单片机，，12c5a60s2， mpu 6050 跷跷板平衡(12c5a60s2， mpu 6050)

给正弦波、方波、三角波等波形进行加噪，可加各种噪声(To sine, square, triangle wave waveform plus noise, you can add all kinds of noise)

单片机开发的最基础教程，适合初学者开发学习用途(MCU development of the most basic tutorial for beginners learning purposes)

说明：  STM32通过模拟IIC读PCF8574(STM32 reading pcf8574 through analog IIC)

在郭天祥单片机开发板上做的一个精确度非常高的时钟，用的是c语言(MCU development board in 郭天祥 an accuracy very high clock c language)

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)
