You are right. Stupid me, I forgot to type the extra brackets while copying :-( > If this is the answer you're expecting, you'd want to use: > #define bd4800 (256 - crystal / (192 * 4800)) I did use that and it still does not give me the correct answer. This is what I have in my header file now : // #define bd4800 (256 - ((crystal / 100) / (2^0 * 16 * 12 * 48))) #define bd4800 (256 - ((crystal / 100) / 9216)) // 244 And that works for now :-) roelof ------------------------------------------------------------------------------ Free Next-Gen Firewall Hardware Offer Buy your Sophos next-gen firewall before the end March 2013 and get the hardware for free!
