Thanks, I thought there should be some conversion thing.
How do I get that into the byte though?
char cStr[256];
int iDec = 100;
byte bByte;
sprintf(cStr, "%x", iDec);
bByte = cStr; //bByte should contain 0x64

That's what I tried, but it doesn't seem to work. I tried reading up on the sprintf, but there's nothing about it in the manual. I assume it's a C thing.
thanks
