Post by thread:SELFMADE PIC-PROGRAMMER FOR DIFFERENT PIC TYPES?

Hi all! I have found on the net some schematics for "A serial programmer for PIC16C84" including software (c-language) and I tried it out! It works! With minimal costs! --> Does anybody know which types of PICS can be programmed serially? --> Can I alter my selfmade programmer to program other PICS than PIC16c84 without bying an expensive programmer? Thanx. Friedrich (spam_OUTf_roschmannTakeThisOuTams.co.at) --- Have a look: The Towers from Hanoi in JavaScript: http://privat.schlund.de/RoschmannFriedrich

You can buy ready-made cheap PIC-programmers at 31 GBP / 390 SEK / 52 USD. Why then build it yourself? I mean, time is also valuable, especially if you possess the valuable technical skill of being able to write PIC software. The above programmer can be bought here: http://www.tripnet.se/~glenn/s.htm Regards, Glenn

In fact, the very first PIC programmer I built evolved into being the center of a project for my brother (which had to interface a PC with a bunch of photo- gates and lights). The programming logic was included in the early versions of the application software, so when I changed the PIC code the application would automatically "burn", execute, and then use the new PIC firmware. This ability may not be needed for every application, but when it's do-able it can save a lot of time.
