My idea as well, and i might add to that, a simple logic probe available for a couple dollars from radio shack/ tandy usually works out great Most software problems you can easy find with one of the pic simulators available Not all of us have money/space for a scope/ logic analiser Peter van Hoof -----Original Message----- From: Pasi T Mustalahti [SMTP:ptmusta@UTU.FI] Sent: Thursday, December 04, 1997 2:15 AM To: PICLIST@MITVMA.MIT.EDU Subject: Re: Do I need a Scope for PIC Projects?

PTM: If you can afford it, hire a R&D laboratory and a bunch of specialists there. If you are in a tight budjet or just for fun take a LED and a 470 Ohm resistor and make an indicator of those so that you can see what goes where. In some sittuations you can use RC instead of Xtal and run your PIC near 0 Hz so you don't need memory scopes. When everything is Ok you throw the Xtal in and there you are. -------------------------------------------------------------------------- PTM, pasi.mustalahti@utu.fi, ptmusta@utu.fi, http://www.utu.fi/~ptmusta Lab.ins.
