for loop condition always true

Question

I have a For loop in C:

u8 i;
for (i=0; i <= 255; i++)
{
    //code
}

Now the compiler complains that "comparison is always true due to limited range of data type" I understand that 255 is u8 max but a for loop must have a condition. What should I put there then? Thanks.

Answer 1

uint8_t i=0;
do {
    //code
}while(++i);

Answer 2

what is u8? if it means 8-bit unsigned int, then 255+1 gives zero again, so the loop starts over again. you should use larger integer type. or use do-while as suggested in replies
