Hello to everyone, i have this example:
union { struct { unsigned char x:4; unsigned char y:4; } nibble; unsigned char abyte; } value;
I'am not sure how to acces to the byte and the two nibble's. I tried several hours, maybe there's a mistake in my textbook? Or there is a fatal error in my understanding of struct and union's!
There's an really idioticall way to solve this: Just toggling thru all permutations of syntax :-( No, better to ask someone who knows and is willing to help :-)
Not sure what your question is exactly but this might help.
union { struct { unsigned char x:4; unsigned char y:4; } nibble; unsigned char abyte; } value; typedef union { struct { unsigned char x:4; unsigned char y:4; } nibble; unsigned char abyte; } tyvalue; int main(void) { tyvalue myvalue; value.abyte = 0x12; value.nibble.x = 0xF; value.nibble.y = 0xF; myvalue.abyte = 0x12; myvalue.nibble.x = 0xF; myvalue.nibble.y = 0xF
