upward migration

[jack11]

I'm considering moving up from the 16F parts to the 18F parts. Any body had any experiences doing this? Is it worth the cost of a new compiler, reworking old code, etc.


thanks

It depends from what chip to what chip you are going to migrate. Recently I updated a project from PIC16F877 to PIC18F442 with almost no effort at all. The only thing you need to do is to fix any #byte or #bit definitions you might have as well as some very minor changes depending on your code.
It is definitely worth the update because the PIC18 chips give you more memory, more modules (timers,...), hardware multiplication, more interrupt sources, priority interrupts,...

I'm moving from the 16f877 also. the 18f sure looks like a better part.
thanks for the input
