Arduino LCD text output & input buttons

ARM9(AT91RM9200)开发板主题驱动-ARM9 (AT91RM9200) theme-driven development board

Atmega88PA，PWM程序，通过UART串口通信控制PWM，是AVR常用的程序，新手可以下载来参考一下。做四轴飞行器入门芯片也常用这个芯片和这个程序。

Presentation on Embedded C

这个是个4个数码管显示时间的程序，用AT89S52实现，用四个按键控制，能实现时钟显示，闹钟定时，倒计时三项功能，电路图很简单。-This is a 4 digital tube display time-consuming procedures, use AT89S52 realize, with four buttons control, can realize the clock display, alarm clock, timer, countdown to the three functions, circuit is very simple.

使用protel99se开发的单片机电路板，希望有助于各位电路板开发设计的学习-Use protel99se developed microcontroller circuit boards, circuit board you wish to contribute to development and design of learning

用于ATmega128的一些通讯程序，包含I2C　UART，SPI等接口，用ICCAVR编译-for ATmega128 some communications procedures, including UART I2C, SPI interfaces with ICCAVR compiler

ALTER的CPLD/FPGA配置芯片的手册，很有用的-ALTER the CPLD/FPGA chip configuration manual, very useful

资源描述 自己在原子的MINI板上写的，DDS然后模拟IIC，两线传输到OLED屏幕上显示当前频率，每次按键更改频率大概需要25us，DDS芯片选用的是AD9850，验证已通过。

ucs2和GBK互相转换的code, 网上的一般是c++, 这是我自己写的. 嵌入式编程里非常有用的哦-UCS2 and GBK transferable code, the Internet is generally c, it is I wrote it myself. Embedded programming Lane very useful oh
