MSP430 CRC算法的实现 （基于msp430x16x）-MSP430 CRC algorithm (based on msp430x16x)

基于等精度测频原理，设计的等精度频率计，测试结果很精确，达到0.01HZ。-Such as the accuracy of frequency measurement based on the principle of design, such as precision frequency meter, test results are accurate to 0.01HZ.

基于AVR单片机mega8的电表的C程序（第三部分，接收数据分析并回答）-Based on the AVR Microcontroller mega8 meter C-program (Part III, to receive data analysis and answers)

可以实现在PC与CAN总线的连接。采用的89C51和SJA1000芯片的接法。里面包括原程序的电路斩-Can be achieved in the PC and CAN bus connection. Used 89C51 and SJA1000 chip connection. Procedures which include the original circuit Tsam

IAR例子，里面是一个完整的定时例子。包含Proteus电路图。-IAR example, which is a complete example of the timing. Include Proteus schematic.

8279初始化以程序，键盘处理程序以及显示子程序-8279 initialization procedure, keyboard and display processing subroutine

计时器，５１源码，芯片是７7E58,精度是10uS，上升沿，下降沿，脉宽都可以测量，８路同时测量，１０个数据存储，指标就这样了-Timer, 51 source code, chip is 77E58, precision is 10uS, rising edge, falling edge, pulse width can be measured, 8-channel simultaneous measurement, 10 data storage, so the indicators

单片机编程的bcd码和hex码的互换，BCD2HEX 例子： c=BCD2HEX(0x255) //255 转成HEX为0xff c=HEX2BCD(0xff) //0xff 转成BCD码为 2-microcontroller programming bcd yards and hex code swap BCD2HEX example : c = BCD2HEX (0x255)// 255 to HEX conversion c = 0xff HEX2BCD (0xff)// 0xff conversion of 255 BCD
