基于单片机8051的嵌入式开发指南主要是rty51和UCOS操作系统的开发.-Based on the 8051 single-chip embedded development guide primarily uCOS rty51 and operating system development.

240128液晶显示的头文件,包括了字符显示子程序与点阵显示子程序-The first liquid crystal display 240,128 documents, including a character display with dot matrix display subroutine subprogram

是用AT89C2051主控音量控制PT2258,数码管显示, 红外线遥控,2.1/5.1音源选择)包括全套原理图,源程序,HEX文件-AT89C2051 is PT2258 master volume control, digital control, infra-red remote control, 2.1/5.1 sources choice), including a full set of schematics, source, the HEX file

PKE（被动无钥门禁系统，汽车车门控制）整个系统基站部分源代码。-PKE (passive-keyless-entry system, car door control) part of the whole system base station source code.

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
