Hi, i'm migrating a 16F628 based system to 18F452 and would like just to confim some things i've searched: 1. 18F452 can be programmed with picstart plus, right? 2. May I use the code I have running in 16F628 in 18F452 with no changes, or at least few changes? 3. The 1,5K of memory that 18F has is all available for user?
