MSP430F147 FLASH功能例程

基于AVR128单片机的简单例程，实验键盘-LED灯的控制，运行良好，可以借鉴~(AVR128 microcontroller based on a simple routine, experimental control of the keyboard-LED lights, well, you can learn ~)

基于STM32+ADS1232+keil温度压力采集(Temperature Pressure Acquisition Based STM32+ADS1232+keil)

说明：  用C语言编写的51单片机智能小车程序；该小车能自行循迹，超声波避障和测距，液晶显示信息以及红外遥控等功能；(The 51 single-chip intelligent car program written in C language can track itself, avoid obstacles and measure distance by ultrasound, display information by LCD and infrared remote control.)

编程菜鸟学习用的蜂鸣器播放八月桂花香声音(Programming rookie learning the buzzer with sound playback 八月桂花香)

名称：门禁模拟 模拟现实中门禁系统，可以输入密码进入也可以呼叫住户，再由住户按下开门按键 实现改密码功能，密码保存在24c02中能保证掉电不丢失密码。八个LED灯分别代表 8家住户，其中开门按键为共用，还带有忘记密码恢复按钮，模拟恢复出厂设置， 显示部分为LCD1602。程序共分为3种模式，分别为 等待输入 密码修改 呼叫住户 3种模式，其中等待输入是主要状态，所以在进入密码修改 呼叫住户模式后如果 长时间没有操作能自己切换到等待输入模式。(Name: Access Analog Simulating real access control system, you can also enter a password to enter the call households, again by pressing the open button households Implement change password function, the password stored in the 24c02 can guarantee non-volatile password. Eight LED lights represent 8 households, which opened the door keys are shared, but also with forgotten password recovery button, analog restore factory settings, Display part LCD1602. Program is divided into three modes, namely, waiting for a password to modify call households 3 modes, which is the main input wait state, so call households entering the password change mode if Their long time operation can be switched to the standby input mode.)
