需求：
有256点数据，每个点有两个取值范围，0表示黑色，1表示白色，然后要把这256个点打包成32个BYTE。
void make_data_package(char buff[] , long out[])
{
char tempBuffer[8] = {0};
char *end ;
for (int i=0 , targetIndex =0, tIndex =0; i<256; i++ , tIndex++ )
{
if( tIndex >=8 )
tIndex = 0;
tempBuffer[tIndex] = buff[i];
printf("%c " , tempBuffer[tIndex]);
if ( (i+1) % 8 ==0) {
printf("\n");
out[targetIndex] =strtol(tempBuffer, &end, 2);
//printf("\nout[%d] = %lx \n" , targetIndex ,out[targetIndex] );
targetIndex++;
}
}
}运行结果：
