红外的收发测试。。通过2路红外发射，顺序接收，检测收发功能是否正常(Infrared transceiver test. . 2-way infrared transmitter, received out of sequence detection transceiver function is normal)

用AT89C51点亮的跑马灯，可以实现最小型的单片机应用。是用c语言编写的。(With AT89C51 lit marquees, you can achieve the most compact single-chip applications. With c language.)

一个ModBus单片机例子 使用AVR(And a ModBus SCM example)

c8051f040 spi功能，硬件spi读写w25X系列EEPRom，包括各寄存器初始化函数(the the c8051f040 spi function hardware spi read and write w25X series EEPRom, including the register initialization function)

说明：  AD模数转换，基础lcd1602显示屏。。。。。。(AD analog-to-digital conversion, basic LCD 1602 display screen...)

广告开发 显示 基于单片机的tx-1c板子！ 好好学习一下 大家可以共同进步！(guanggao kaifa xianshi jiyu danpianji )

PIC Microcontroller project Door lock with PIC16f84a

本程序目的是提供使用stm32串口收发一帧数据的一种方法，采用中断方式接受和发送，每进一次中断接收或发送一字节，可以实现pc机与板子通信或板子与板子间通信。注意本程序中外接高速晶振为12M赫兹，而大部分板子为8M赫兹，本程序所用芯片是stm32RBT6(The purpose of this procedure is to provide a method of using STM32 serial port to send and receive a data, using interrupt mode to receive and send, every one into the time interrupt receiving or sending a byte, can realize PC and the communication or board and board communication. Note that this procedure the external high-speed crystal oscillator for the 12M Hz, while the majority of board is 8M Hz, the chip used in this procedure is stm32RBT6)

说明：  野火官方基于OV5640解码二维码例程。单片机是F429.解码部分代码可以移植至其他IC。此库已经用在公司项目二维码门禁反扫功能上。(Wildfire officials decode two-dimensional code routines based on ov5640. The MCU is f429. The decoding part of the code can be transplanted to other IC. This library has been used in the company project QR code access control anti scanning function.)
