LPC2103,74HC164，IAR下程序

利用串口和单片机进行通讯,VC用对话框实现-use serial communication and microcontroller, the VC using Dialog

用单片机 AVR mega48 和 tinny13做的 AVRCDC-With MCU AVR mega48 and tinny13 do AVRCDC

环境是IAR,本实例应用于大棚或是其他需要温度控制的场合，可以供大家参考一下。-Environment is the IAR, the examples used in greenhouses or other occasions the need for temperature control, you can refer to for everyone.

单片机扫描状态机的程序实现，希望能帮助到有需要的朋友。-Single-chip state machine to scan the program, hoping to help a friend in need.

此程序为AD9850（DDS）直接数字频率合成器C语言源码。用125M的有源晶振，频率无失真输出可达到40M。该程序包括FYD12864LCD显示程序加4X4矩阵键盘扫描，可步进1M，1K，和任意频率输入。及相位设置。-This procedure for the AD9850 (DDS) Direct Digital Frequency Synthesizer C language source code. With 125M active crystal, the frequency output can be achieved without distortion 40M. The process includes the display program FYD12864LCD plus 4X4 matrix keyboard scanning, may be stepping 1M, 1K, and arbitrary frequency input. And phase settings.
