经典的汇编语言程序！是把书上理论的不好 理解的原理用程序表达出来！...

优点：中断中只做很少的事情，通常我是在接收中断中post一个信号量，触发别的任务读数据-Advantages: only a small interruption in the things I usually post in the receiving a signal interruption in the amount of time to trigger other mission data

C8051F单片机是完全集成的混合信号系统级芯片（SoC），具有与8051兼容的高速CIP-51内核，与MCS-51指令集完全兼容，片内集成了数据采集和控制系统中常用的模拟、数字外设及其他功能部件；内置FLASH程序存储器、内部RAM，大部分器件内部还有位于外部数据存储器空间的RAM，即XRAM。C8051F单片机具有片内调试电路，通过4脚的JTAG接口可以进行非侵入式、全速的在系统调试。-C8051F is a fully integrated mixed-signal system-on-chip (SoC), and 8051 compatible with the high-speed CIP-51 core, and MCS-51 compatible instruction set, on-chip integration of the data acquisition and control system used in analog and digital peripherals, and other functional components; embedded Flash program memory, internal RAM, the majority of devices located within the external data memory space of RAM, XRAM. C8051F with on-chip debug circuit, through the four legs of the JTAG interface can be non-invasive, full-speed debugging of the system.

用C语言写的红外遥控解码程序，，，， 语法上没错，但解码完成后有错，，没个按键的都一样，，不知道什么问题，望指点，，EMAIL:wjsjdeng@sina.com.cn-C language to write the infrared remote control decoder,, the grammar is correct, but after the completion of decoding wrong, not a button are the same, and do not know what, look a spot, EMAIL : wjsjdeng@sina.com.cn

本装置是一个以HT46R71D 为主芯片，配合传感器组成的汽车轮胎气压检测装 置，最终取高三位有效值于LCD 显示，有四种显示单位供切换（Psi、Bar、Kpa、 Kgf/cm2）。本装置仅为参考范例，使用时，为提高准确度，建议多量测些组数 据来构建Sensor Output Voltage - Discharge Time (V-T)表格，并作相应校准。-This device is a HT46R71D-based chips, with sensors detecting vehicle tire pressure devices, and ultimately take the high-three RMS in LCD display, there are four types of display units for switching (Psi, Bar, Kpa, Kgf/cm2). Only reference to an example of the device, when used to improve the accuracy of the proposed多量measured set of data to build more Sensor Output Voltage- Discharge Time (VT) forms, and the corresponding calibration.
