ICCavr的硬件读写IIC有完整的应用说明

基于C51的DS1820测温的C语言源程序，有详细注释-c51 program about tempreture data acquisiton

在对存储空间要求非常严格的嵌入式系统中用CPU下载CPLD的代码，比如51系列的单片机。-storage space in the very strict requirements of embedded CPU system used to download CPLD code, for example, the MCU 51.

本文介绍了两种分频系数为整数或半整数的可控分频器的设计方法。其中之一可以实现50％的奇数分频。利用VHDL语言编程，并用QUARTERS||4.0进行仿真，用 FPGA 芯片实现。 关键词：半整数，可控分频器，VHDL, FPGA -This article describes two kinds of sub-frequency coefficient is an integer or half-integer divider controllable design method. One of them can achieve 50 of the odd-numbered sub-frequency. The use of VHDL language programming, and QUARTERS | | 4.0 simulation, using FPGA chip. Key words: semi-integer, controllable divider, VHDL, FPGA

在MSP430下操作IC卡以及FLASH以及ADS1242-operate under the MSP430 IC cards and FLASH and ADS1242

本软件是单片机通讯的主程序，通过串口传送数据。-This software is the main single-chip communications, through the serial transmission of data.

GPS开发，单片机接受代码，对于使用者非常重要-GPS

IIc应用子程序，此程序可应用AT24C08等等串行EEPROM芯片的开发和学习使用，此程序调试通过-IIc application subroutine, this procedure can be applied so AT24C08 serial EEPROM chip development and learning to use, this program debugging through

系统can地址为550,用于can系统测试,应用T0定时器每隔1s向can总线发送一组数据:数据长度为8个字节, 首字节为05H,第二个字节为累加变量,每秒钟数值增加1,-system can address 550 for the test system can, Application T0 1s to every timer can send a bus of data : data length of 8 bytes the first byte of 05H, the second byte of cumulative variable, an increase in value per second.

C51常用字程序，单片及开发中的常用程序，缩小巧但很实用，而且包括的面很广，有很强的借鉴价值！-C51 characters commonly used procedures, and development of a single common procedures, and narrow the cleverest but very useful, but also the broad-based and has a strong reference value!
