Do what you prefer... Do you like soldering more than programming, then use a single PIC... Do you get off on a programming challenge, like multiple serial communitacion in software, use the small PIC... ----- Original Message ----- From: "Shawn Wilton" To: Sent: Tuesday, April 13, 2004 2:15 AM Subject: Re: [PIC:] Is it better to use Shift Registers or lots of I/O? > I would go with the shift register so if something happens, you're not > sinking all that current through the =B5Controller, but rather through = a > cheap chip. > > -Shawn > > Jason S wrote: > > >I'm working on a project that will need a couple of inputs and around = 16 > >outputs.
