单片机C51的应用,高精度实时时钟－SD2001驱动程序的源码 -C51 microcontroller applications, high-precision real-time clock-SD2001 driver source code

基于DS18B20的温度计，用C51编程 时钟控制的很精确，调试成功的程序，没有问题，可以很方便的移植-Based on the thermometer DS18B20 with C51 programming clock control is very accurate, debugging successful procedures, there is no problem, you can easily transplant

avrrice软件用于AVR单片机的JTAG调试.-avrrice software for AVR JTAG debugging.

绘图型 LCD 数字时钟 使用单片机控制外围LCD 自己制作的电子时钟，很好用的！-Graphics-based LCD digital clock to control the use of single-chip peripherals to produce their own LCD electronic clock, very good use!

本人收集的一些C语言程序，谢谢大家的光临 希望对你们有所帮助-I collected a number of C language programming, thank you all for coming hope to help you

单片机用T1中断在IO口P1.0输出乐曲(在P1.0口与VCC间接一喇叭即可听到) 1.由于输出的是方波，比较难听:-)你也可以将波形细分用DA输出正弦波 2.由于T1频繁中断，任何其他中断发生都会是乐曲打顿，只适合试验 3.优化音符编码：一个字节中包含节拍、音符、升降调，可区分数据和命令 -Single-chip microcomputer used in the IO port T1 interrupt output music P1.0 (P1.0 port with VCC in the indirect one can hear the speaker) 1. As the output is a square wave, more bluntly :-) You can also fine-waveform DA output sine wave with sub-2. Due to the frequent interruption of T1, any other interruption occurs Dayton will be playing music, is only suitable for test 3. optimized coding notes: A byte contains rhythms, notes, take-off and landing tune can distinguish between data and command
