Re: [Sdcc-user] sdcc and PIC18F2550 ?

[George M. G. Jr. <gga...@co...>]

Michel,

PIC18F2550 if a nice step up. PIC24F or dsPIC33 is even a nicer. Similar
cost & pinout. 16 bit instructions with linear data space. These parts
are 3.3V with limited tolerance for 5.0V I/O. Some also have user
configuration pinout,
