You may try like this:
#define SET_BITS_LOW ((unsigned char)0x80)
Question
I would like to know how can I tell to compiler that a #define
is an unsigned char.
#define SET_BITS_LOW 0x80
Here SET_BITS_LOW
is, by default, an int but I want an unsigned char
Solution
You may try like this:
#define SET_BITS_LOW ((unsigned char)0x80)
