Post by thread:[PIC]: ICD modified

I have just finished a modified ICD, see http://www.vitrum.cz/snail/icd.htm It is build on a single sided board. Complete schematic, silkscreen and PCB pictures are published, also PCB solder side postscript file and Eagle 3.55 schematic and board files are available for download. Enjoy. I also considered offerring kits, those would include all the parts, PCB and preprogrammed PIC16F876 to solve the egg-chicken problem. Will there be any insterest if they are priced at $39? Let me know. Josef -- http://www.piclist.com hint: To leave the PICList spam_OUTpiclist-unsubscribe-requestTakeThisOuTmitvma.mit.edu>

Actually come to think of it copying the idea and selling it is pretty dubious morally.

Great work and nice of you to share it. BTW, I briefly looked at the schematic on your page. I didnt really check it much, but I noticed one thing that might be an error, or maybe its a microchip error that you have fixed. Anyway, you have R33 shown as 10 Kohms, but in the schematic I got from microchip, its shown as 100 Ohms. ?? -- http://www.piclist.com hint: To leave the PICList piclist-unsubscribe-requestspam_OUTmitvma.mit.edu>

Thanks, it looks great! Last time I tried to get an ICD from Digi-Key they were out of stock, I think I'll build one of these this weekend. > I also considered offerring kits, those would include all the parts, PCB > and preprogrammed PIC16F876 to solve the egg-chicken problem.

You'll get a lot of interest for free kits, though :-) Most people with money and credit cards will opt to buy a Microchip ICD(if they can find one!). Thanks again.

Did you try getting it from advanced-transdata or its resellers? http://www.adv-transdata.com Cheers, Ling SM >Selling kits has always seemed like a lot of work.

Hi Brian, >> I have just finished a modified ICD, see http://www.vitrum.cz/snail/icd.htm > >I don't understand why you have modified it. The original is much better >because it works without a 15V supply. I just didn't like the idea that every project would have to provide some 50mA of spare power just for the few minutes (well, maybe hours :-) of debugging. Since you need a PC anyway, I see no problem powering the ICD from a wallwart. >To copy the Microchip software and then sell it would surely be illegal, or at >least morally highly dubious. We discussed this earlier when MPLAB 5.00 was released and the idea of free ICD appeared. The conclusion was that hobbyist on a budget wouldn't buy ICD even for $159. Furthermore Microchip doesn't make money on development tools (at the seminar they called them the necessary evil). And Microchip can still benefit even from homebrew ICD, in the long run. I was of course aware of this issue, but once someone decides to spin off his ICD clone, he has to put the code in the PIC somehow. Will it be less immoral if he does it himself?

Hi Don, I believe both 100R and 10K are correct. If you have a look how RB6 and RB7 of the target are driven (signals are named RC3X, RC4X to ease up orientation :-), there is 330R from the 'driving' pin and 10K to the 'sense' pin. ICD firmware undoubtly checks that the target does not override applied signal levels. Since the R33 goes to the so far unused RCX0 (supposed to drive target RB3), I guess the resistor value doesn't matter at all. Even if the RCX0 is used in future firmware upgrades, the sense pin will see correct level thru 100R as well as 10K resistor. Josef >BTW, I briefly looked at the schematic on your page.

I thank to all, who have replied to my ICD post so far. I didn't mention I am subscribed to the digest, so a carbon copy to TakeThisOuTsnailEraseMEspam_OUTiol.cz would mean a faster response. But it was the Independence Day yesterday anyway, right?

Have you ever tried getting any response from Advanced-Transdata? They like to ignore me... ...I can pick up the phone and talk to the bloody president of Parallax Inc and at least to my FAE for Microchip but no human answers the phone or returns emails from AT. I'm curious as to the ownership of the ICD. Microchip makes its every detail available in a pdf. The board says Advanced-Transdata. My sources say it was designed by Microchip. At best AT has an option to produce it. Did you know there are quite a few others? http://www.propic2.com http://www.magenta2000.co.uk/kits/900.htm http://www.diversifiedengineering.net/Ed%20Board.htm ...just to start the list. How many more? see http://www.piclist.com/../microchip/icd or www.piclist.com/techref/default.asp?url=microchip/icd for more. --- James Newton (PICList Admin #3) jamesnewtonEraseME.....piclist.com 1-619-652-0593 PIC/PICList FAQ: http://www.piclist.com or .org {Original Message removed}

Or you could try Farnell... I have ordered a ICD, wich came in damaged. So i send it back. They told me the ICD's were out of stock, but yesterday i received an ICD from Farnell (http://www.farnell.com) Also, in the netherlands you could order one from Avnet SEI, who have told me they have the ICD's in stock! (i thought their site was http://www.avnet.nl / http://www.avnet.com or a search would prove otherwise :) Regards, Jilles Oldenbeuving EraseMEjillesrendo.dekooi.nl -----Oorspronkelijk bericht----- Van: V sml <RemoveMEdecoderEraseMEEraseMEBIGFOOT.COM> Aan: RemoveMEPICLISTspam_OUTKILLspamMITVMA.MIT.EDU <RemoveMEPICLISTTakeThisOuTspamMITVMA.MIT.EDU> Datum: woensdag 5 juli 2000 4:12 Onderwerp: Re: [PIC]: ICD modified {Quote hidden}>Did you try getting it from advanced-transdata or its resellers? > >http://www.adv-transdata.com > >Cheers, Ling SM > >>Selling kits has always seemed like a lot of work.
