This application report describes the use of Timer_A3 to decode RC5 and SIRC TV IR remote control signals. The decoder described in this report is interrupt-driven and operates a background function using specific features the Timer_A3. Only a small portion of the MSP430 CPU?s nonreal-time resources ...

可以分析出TS流文件的软件，有兴趣的可以下来玩玩。对初学PSI/SI标准的朋友很有用

Using Gaussian elimination to solve linear equations. // In this version, we allow matrix of any size. This is done by treating // the name of a 2-dimensional array as pointer to the beginning of the // array. This makes use of the fact that arrays in C are stored in // row-major order.

设计任务及要求 1. 以8255接八个开关K1~K8，做电子琴按键输入。 2. 以8253控制扬声器，使用简易键盘，发出相应的音阶。 要求： K1—静音 K2—发si的音493Hz K3—发la的音440Hz K4—发sol的音392Hz K5—发fa的音349Hz K6—发mi的音329Hz K7—发re的音293Hz K8—发do的音261Hz ...

按C51格式生成汉字字模的.c及.h的windows C源码， 你只需要把需要的汉字在confighz.h中定义，本套程序自动生成c51格式的hzkcode.c和hzkdef.h两个文件。 本套程序需要用家自己编译。 如果生成12点阵，用TC 3编译buildHZ，从HZK12.GBK读入GBK字模。 如果生成16点以上的字模，请用ming编译freeHZ，它利用freetype.org库从truet ...

简单的floyd运用 第一行输入一个整数C。C是测试的情况（0< C <=30）.第二行一个正整数N( 0< N <=100),表示道路的总数.紧接N行，每一行包含两个字符串， Si,，Ti，和一个整数Di,代表从Si到Ti的距离(0<= Di <=150)。最后一行有两个字符串，S 和 T，你得找出从S 到 T的最短的距离。地名是不超过120个小写字符的串（从‘a’到 ...

This program accesses a SPI EEPROM using polled mode access. The F12x MCU is configured in 4-wire Single Master Mode, and the EEPROM is the only slave device connected to the SPI bus. The read/write operations are tailored to access a Microchip 4 kB EEPROM
