hi,i 've tried my core chip 18F452 with an id 7 and no data on the lcd ..is it possible ..(.like the sid ,i ve build and i’ve changed the id)that i must have only an id 0? thanks
that would make the most sense seeing as you only have one core in an MBFM. ;D
[edit] also, you may want to go with an 18f4685 (as i’ve learned) for future expansions in the firmware. just a thought. 
thanks;i 've learned this too,but 1 or 2 years waiting… :
