-----Original Message----- From: pic microcontroller discussion list [spam_OUTPICLISTTakeThisOuTMITVMA.MIT.EDU]On Behalf Of Matt Johnson Sent: Tuesday, September 24, 2002 4:42 PM To: .....PICLISTKILLspam@spam@MITVMA.MIT.EDU Subject: Stupid Question I am new to this. I was wondering for this beginner circuit: http://www.piclist.com/techref/piclist/cheapic/bincnt.htm does the C = 33pf designate a Crystal? if not, if it is a capacitor then I am confused by the drawing because it says 32.768 kHz but does not show an icon for the crystal. IT MOST CERTAINLY DOES! Which leads me to a generic question. When designing a circuit how do you choose which crystal to use? What timing functions do you need in the design? what serial communications? do all projects use the same generally? None of mine do. what brand and part number? This is too much... Also, what other components need to be ordered (like 5v regulator, etc). I am going to make an order to digikey and I dont want to get the stuff and realize I have to place a whole other order becasue I forgot some stupid support component... ^^^^^^^ You do the COMPLETE specification and design BEFORE you order parts like crystals etc. You also take the time to spell check before posting, you add [PIC] to the subject, if you want to avoid Olinisms. - Matt -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!

Thomas, have you ever heard of experimenting and learning? I dont have a specification so there is nothing to plan. I just want to fool around with some sample projects of all kinds. As for the spell check, I am using a unix text email client and it doesnt spell check before sending. As for the [PIC] I am sorry, I am new and forgot. Thanks for your extremely helpful reply and your joyful attitude. - Matt On Tue, 24 Sep 2002, Thomas C. Sefranek wrote: > {Original Message removed}

Hi Matt, if your new to PICs you might want to check out http://www.phanderson.com/ordering_1.html He has prices for small quantities of everything you would need to get started. Including his $2 logic probe kit and $12 power supply kit. Also check out Tony Nixon's Tutorial at http://www.bubblesoftonline.com/projects.zip You can also look at http://www4.tpg.com.au/users/talking/ for some intro to electronics and pics -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!

Matt, THere are no stupid questions. In other words, any question is a valid one and often generates unexpected answers. Keep posting good questions. Glad to see you are experimenting around with this stuff. I started out by buying a dozen op amps and plugging 11 of them in backwards before I figured out what the little dimple on pin 1 was for. If I'd had a PIClist to ask dumb questions on I would have only fried 3 or 4 of them. BTW I can't spEll neiTher. Ignore these wags who are a little too PICky sometimes about irrelevant things like SpeLLin. Gruff Posts about bad spelling are what the delete key was designed for. -- Lawrence Lile > > I am going to make an order to digikey and I > dont want to get the stuff and realize I have to place a whole other order > becasue I forgot some stupid support component... > ^^^^^^^ > > You do the COMPLETE specification and design BEFORE you order parts like > crystals etc. You also take the time to spell check before posting, you > add [PIC] to the subject, if you want to avoid Olinisms. > -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!

Actually, IMHO, there is one foolish question. The question that is not asked (possibly for fear of looking foolish) because that question has NO hope of being answered.
