Post by thread:ProPic 2.5

Hi, There was a discution about the ProPic software a few days ago. I fixed some bugs in the software and hardware and putted a new version V2.5 in my homepage. Everyone using ProPic should update. I'm not asking for money anymore because I don't do this for living, but if you like the Software and want to send me something you still can register. Best regards, Octavio -- ======================================================== Octavio Nogueira e-mail: spam_OUTnogueiraTakeThisOuTmandic.com.br homepage: http://ourworld.compuserve.com/homepages/tato voice/fax: +55 11 240-6474 "ProPic" The first Production PIC Programmer running in Windows and under US$ 20.00. ========================================================

I have decided to build and test the Propic 2.5 programmer and was wondering if the smaller pics (18 pin etc) just slot into the 40 pin zif with pin 1 adjacent to the pin 1 on the zif. Also if they can just plug in without any damage occuring to the device and whether the software and hardware has any problems. Thanks in advance. Justin

Octavio was pretty helpful and suggested adding a little capacitor to one of the data lines when mine wouldn't program. When I get some time I will add the production programming options, and start on a 16C73 project I have in mind. I will probably re-design the power supply to use a 317 for the programming voltage instead of the 7808. This will allow me to adjust the program supply too. I built mine on strip board, but if you fancy designing a neat PCB for it I would love a copy. Octavio could probably post it on his page too.

As for the PCB I will probably use stripboard but might design a PCB layout anyway with Autotrax. By the way where does that little cap go... Thanks Justin

I think the current version has a slightly different buffering arrangement. Let me know how you get on, Keith. ========================================================== Keith Dowsett "Variables won't; constants aren't."

I've just finished making a PCB for the PicPro 2.5 (using Advanced PCB/Schematic - Protel for Windows). The PCB matches Octavio's original schematic, except that it uses a LM317L instead of the 7808. Furthermore I've changed the V-reg. output capacitors. It includes the 'production-mode' programming (extra LM317L+trim-pots). The PCB is single sided, approx. 10*7cm, space for zif-socket and a socket for in-circuit programming. Smallest clearence/track-width are 15mils, which should make it easy to make 'at home'. If anybody wants the PCB+schematic, I'll post it in personal E-mail as soon as I've etched/tested it (beginning of next week). -Jacob Blichfeldt KILLspamblchfldtKILLspampost3.tele.dk

Once it works could you send me the Protel files too, I think our electronics lab can read them (providing I ask very nicely).
