采用UART方式0与LM74通信。 用C8051f020的P0.7作片选，主机通过TXD发送时钟信号，实现同步通信,半双工.RXD 作双向数据线.用六位

本文件是ATMEGA16A的使用说明，内附该单片机内部各个资源的C代码和汇编代码-This document is the use of ATMEGA16A that the single chip containing all the resources within the C code and assembly code

使用AVR单片机控制的温控与定时,时间从0至99小时99分99秒,温度从-55度到99度.-AVR single-chip microcomputer to control the use of temperature control and timing, the time from 0-99 hours 99 minutes 99 seconds, temperature from-55 degrees to 99 degrees.

用L298作为驱动器，控制两相混合式步进电机。 按键从上至下分别为减速，加速，正转，反转，停止。 具体参数还没有设定过。速度有些慢，加速按2下有效，然后就不能再快了。 转速输出是按照最小系统版的数码管写的。电路图里太麻烦就没画了。-Using L298 as the drive to control two-phase hybrid stepping motor. Buttons from top to bottom respectively, deceleration, acceleration, are being transferred, reverse, stop. Specific parameters have not yet been set. Some of the slow speed, speed up by 2, effectively, and then can not be faster. Speed output is in accordance with the minimum system version of the digital tube wrote. Circuit where not too much trouble drew.

该程序是个蜂鸣器的调试程序，歌曲是兰花草-The program is a debug procedures buzzer, songs are兰花草

是关于sd卡的接口电路图以及pcb封装原理图 是sd卡驱动者重要的资料-Is on the sd card interface circuit and the pcb schematic package sd card driver is important information

基于MSP430的AD转换，可以加以修改成为单独模块应用。-MSP430 Based on the AD converter, you can modify the application of a separate module.
