i2c总线协议

这是ATmega128开发板的原理图和PCB文件，没有问题，用Protel 99直接就可以打开，已经打样测试过，很有参考价值。(This is the ATmega128 development board schematic and PCB files, no problem, using Protel 99 directly on the can open, have been tested proofing, great reference value.)

实现ti公司的tm4c1294的板载硬件can通信(Realization of on-board hardware can communication of tm4c1294 of TI company)

40个单片机的小程序，适合与单片价的入门与进阶，是我平时搜集的(40 small single-chip process for the entry price with a single and advanced, is my usual collection of)

利用可编程计数/定时器8253设计一个应用于生产流水线的自动计数系统。通过具体阐述8253的工作原理，系统的软、硬件设计原理以实现系统所需定时、计数、中断等功能，并驱动扬声器发出所需频率的声音。(Using the programmable counts/timer 8253 design a applied to production line of automatic counting systems. Through the concrete 8253 working principle, hardware and software of the system design principle to achieve system, such as timing, counting, and drive a loudspeaker functions required sounds.)

使用CC2530读取SHT20传感器的温湿度数据并发送或串口打印(This program get temperature and humidity data by SHT20 and send data though cc2530 with wireless or usart.)
