利用C8051F020作为控制器，对74LS165进行控制-C8051F020 use as a controller, control of the 74LS165

80C52单片机上用C语言实现的双机红外通信程序，可以替代遥控器遥控长虹电视机，具有一定的学习性功能。-80C52 single-chip using C language to achieve the two-plane infrared communication program, an alternative to Changhong TV remote control, the study has certain features.

8253的初始化程序举例: 例1：选择2号计数器，工作在3方式，计数初值为533H（2个字节），采用二进制计数。其初始化程序段为 MOV DX，307H ；命令口 MOV AL，10110110B ；2号计数器的初始化命 令字 OUT DX，AL ；写入命令寄存器 MOV DX，306H ；2号计数器数据口 MOV AX，533H ；计数初值 OUT DX，AL ；选送低字节到2号计数器 MOV AL，AH ；取高字节送AL OUT DX，AL ；后送高字节到2号计数器 -8253 initialization procedures examples : Example 1 : Select counters on the 2nd, in three ways. Counting for the initial 533H (2 bytes), a binary counting. Initialization of its procedures for MOV DX, 307H; I ordered MOV AL, 10110110B; on the 2nd Counter initialize command word OUT DX, AL; write commands Register MOV DX, 306H; data on the 2nd Counter I MOV AX, 533H; Counting initial OUT DX, AL; low-byte sent to the 2nd Counter MOV AL, AH; With a high-byte send AL OUT DX, AL; evacuations high byte counter to the 2nd

基于飞利浦 lpc2104 arm7 微处理器的部分程序-Microprocessor-based Philips lpc2104 arm7 Part of the procedure

在ADS编译环境以及keil-ARM这两种编译环境下通用的arm-core头文件，并用金鹏串行12864进行验证，用此arm-core开发程序可以不受编译器头文件缺少的限制-In the ADS environment and compiler keil-ARM compiler environment of these two common arm-core header files, and verify Jinpeng serial 12864, with the arm-core development programs can not be the first document of the lack of compiler restrictions

ds12c87读写程序，经过测试是可以用的。-ds12c87 literacy procedures, the test can be used.

C8051F020的头文件，主要是本单片机的硬件地址指向等。-C8051F020 the first document, is the MCU hardware addresses at the other.
