Advice wanted Supporting a new processor variant

I need to develop code for the PIC18F97J60 which is not yet supported by CCS. I was thinking I should be able to compile for the PIC18F87J10 and then handle the addition Ethernet peripheral myself.

Any suggestions or comments welcome.

Do you have PCH, or PCWH?. With the latter, the inbuilt 'device editor', is the 'answer'. Select the chip that is the closest variant (as you have already done), and 'copy' this. Rename the copy, and also copy the .h file (renaming in the same way). If there is another chip that has got the extra peripheral(s) required, then the interrupts etc., for these, will already exist, and can be enabled in the device editor.

Thanks,

I use PCH - I only use 18F series PIC and therefore (previously) I could not justify the price differential to PCWH.

Your biggest problem will them be if you need interrupt support for the ethernet device. You will have to write your own 'int_global' handler. :-(
