I am using LPC2138, is u32 faster than u8?

Posted by Paul on January 5, 2007
I need a fast for loop using i as the counter.
Do I need to define it as 4 bytes variable or 1 byte?
The counter will never go over 64.
So logically u32 is same as u8.
But which one is faster?

Thanks

Paul

This is not really a FreeRTOS.org question - but yes. u32 is better.
