PRINTF doesn't print leading zeroes

michaelellis — Thu, 10 Nov 2016 18:50:47 GMT

SDK v.2.0 for TWR-KV58F220M

The PRINTF function does not seem to print leading zeroes. For example:

PRINTF("0x%08X\n\r", 0xabcdef42U);
PRINTF("0x%08X\n\r", 0xabcdefU);

generates an output of:

0xABCDEF42
0x ABCDEF

Hi, Michael,

I think the Printf() function omits the leading zero, this is a normal behaviour.

Sorry for not helping you.

Why is this normal behavior? To my understanding, printf() should print leading zeroes when using the %08X format.
