超声波测距资料(HC-SR04)_TB参考文档及原理图源程序(Ultrasonic Ranging Data (HC-SR04) _TB reference documentation and schematic source)

AOC品牌液晶显示器源代码，稳定量产版本。C语言，keil编译器，Realtek处理IC。完整的source insight和keil工程，对液晶显示器开发着非常有意义。(AOC brand LCD display source code, stable production version. C language, keil compiler, Realtek processing IC. Complete source insight and keil project, to develop a very meaningful LCD display.)

基于单片机的电子称实验 希望大家能够喜欢 用的是51系列单片机(Microcontroller-based electronics experiments hope you will enjoy with the 51 series)

ht1261 STM32 驱动，亲测可用(ht1621 driver for STM32.tested.)

单片机用作通用红外遥控接收器的设计 PWM调制开关电源的研究 以电子电力学为核心 以整流技术为主(generic microcontroller for infrared remote control receiver design PWM switching power supply of electronic learning for power to the core technology-based rectifier)

说明：  stm32f4系列开发手册中文，方便查找用途广泛(Stm32f4 series development manual in Chinese, easy to find and widely used)

呼吸灯 本模板加载了STM32F103内部的RCC时钟设置，并加入了利用滴答定时器的延时函数。 可根据自己的需要增加或删减。(Breathing lamp This template loads the RCC clock settings inside STM32F103 and adds a delay function using a tick timer. It can be added or deleted according to its own needs.)

说明：  ，用来控制带i2c的风扇板及读写e2prom都没问题，但是用来进行两个AVR单片机之间的通信时，有时会出现数据发送和接收错误（单片机AT1281的TWI引脚连接到i2c缓冲器PCA9513上，通信是在ATCA六槽机箱中进行，但是只用了两个槽位，其他的悬空(That is used to control with the i2c fan board and literacy e2prom all right, but used for two AVR of communication between the microcontroller, can appear sometimes sending and receiving data error (SCM AT1281 of TWI pin connected to the i2c buffer PCA9513, communication is in ATCA six slot chassis, but only two slots, other suspended)

控制台界面的STM32单片机Bootloader 实现固件更新、固件管理、启动管理等功能 可使用超级终端或者自编上位机软件进行操作(Console interface STM32 microcontroller the Bootloader firmware update, firmware management, startup management functions can use HyperTerminal or self PC software operation)
