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 is used. Specific hardware bit-latching capabilities of the Timer_A3 module are used for real-time decoding of the IR data signal, independent and asynchronous to the CPU. CPU activity and power consumption are kept to an absolute minimum level. The Timer_A3 decoder implementation also allows other tasks to occur simultaneously if required. The solutions provided are written specifically for MSP430x11x(1) and MSP430x12x derivatives, but can be adapted to any other MSP430 incorporating Timer_A3. 電視遙控器設計基於MSP430

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.

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‘z’)。假设这里最多有100条直接连通两个地方的路。 Output 输出包含C行,每一行对一种测试情况。对每一种测试情况,输出包含一个整数,假如S 到 T存在一条最短的路,输出从S到T的最短距离,否则输出“-1”.
