2. make a small change to the portA settings in my code, as the 4620 has a different width.

Other than that it works well, as far as I can tell. I2C worked without any mods, not using PWM so don't know about that. Code's up to 37k now, 20Mhz,32bit math, multiple menus, LCD, HSER, Membrane keypads, interupts etc...

Chips from Digikey, $1 more than the 452 for an extra 32k code space, not a difficult decision.

need any help, let me know
Hi i am from singapore, currently working with a team of members on the zigbee kit with pic18f4620 controller. We had some codes that we done done on 18f452. We need to migrate the codes from 18f452 to 18f4620. How should we do it? can someone in here guide us please?

we are also using Hi-tech C languages on this programming schemes, so if possible, some guidance or source codes is needed too. Thx
