cal_crc8.c

用MSP430F149控制普通射频芯片CC1000的双向通信程序（串口、液晶显示）

#include "CRC8_Table.h"
typedef unsigned char uchar;
typedef unsigned int  uint;

uchar Cal_CRC8(uchar *ptr, uchar len) 
{ 
    uchar index; // CRC8校验表格索引 
    uchar crc8 = 0; // CRC8字节初始化 
    
    // 进行CRC8位校验 
    while(len--)
    { 
        index = crc8 ^ (*ptr++);  
        crc8 = CRC8table[index]; 
    } 

    return crc8; // 返回CRC8校验数据 
}
