用一个uchar 类型表示八个通道的状态

//描述：用一个参数uchar 表示八个通道的状态，可以方便传参uint8_t num = 0;//通道的状态
//备注：uint8_t 就是uchar
//调用直接输出所有通道的状态
void read_sta(uint8_t ch_num)
{for(int i=0; i<6; i++){printf("i = %d, s= [%d]\r\n",i+1, ( (ch_num & (1 << i) )>0 ? 1 : 0 ));}
}//一个通道一个通道的写入 ch_num通道状态
int write_sta(uint8_t ch_num){return num |= (1 << (ch_num-1));
}int main()
{int value = write_sta(1);printf("1value = %#x\n",value);value = write_sta(2);printf("2value = %#x\n",value);value = write_sta(3);printf("3value = %#x\n",value);value = write_sta(4);printf("1value = %#x\n",value);value = write_sta(5);printf("2value = %#x\n",value);value = write_sta(6);printf("3value = %#x\n",value);read_sta(value);return 0;
