char to hex value

Ploumen Loïc

Hello,
I have a little problem displaying a char to an hex value.

char t;
t = 0x01;
printf("%x",t);
This code outputs 100 where I expected to get 1... Am I doing something wrong ?

    "Am I doing something wrong ?"

    As Neil says: yes - you are failing to read the manual

    This issue is specifically discussed in the manual.

    If you put your cursor on 'printf' in the uVision editor window, then press F1, it will bring up the library help for printf - which includes the descriptions of the format specifiers, and the notes about char and int.
