Post by thread:[PIC]:P16PRO

Hi I am looking at the P16pro schematic. and i only find a 18 pin socket for the pic, when they claim support for 28 and 40 pin device like the 16f876 and 16f877. How can you explain the difference between the schematic and the documentation. Thanks for your collaboration Gilles Auger spam_OUTgaugerTakeThisOuTsympatico.ca -- http://www.piclist.com hint: To leave the PICList .....piclist-unsubscribe-requestKILLspam@spam@mitvma.mit.edu

Hi, It definitely works for the 28 and 40 pin devices - I have a device here on my desk - its all just a 5-connection serial link anyway (clk, data, +5V, gnd and programming voltage). If you want to know more, theres a review on http://www.workingtechnologies.com/htpic/PICALL_review.htm. Cheers, Shane. > {Original Message removed}

If you read the sheet that comes with the board, and look at the silkscreen on the board, you will realize that space was allowed for all 3 of 18 pin, 28 pin and 40 pin sockets. Only an 18 pin socket is supplied with the board. If you wish to program all of the various parts, you should buy a 40 pin "wide" (e.g. Aries) ZIF socket and solder that to the board instead of the 18 pin socket. You will then be able to program any of the 18, 28 or 40 pin chips by inserting them in the specified positions on the 40 pin ZIF socket. You could also use a cheaper, ordinary 40 pin socket, but you will have great difficulty inserting and removing the large chips from it. A ZIF is really necessary for 28 and 40 pin chips. It also works better for even the 18 pin chips. ================================================================ Robert A. LaBudde, PhD, PAS, Dpl.

The circuitry for the 8, 18, 28, and 40 pin devices is all the same. The difference is which pin gets which signal. I found a 'kit' of this programmer at the local electronics shop. As someone else mentioned, it came with 3 sockets, and silscreen for them. Instead, I purchased a 40-pin ZIF socket. To program my 18 pic PICs, I put the chip in the bottom of the socket, so that pin 9 of the chip is in pin 20 of the socket. The circuit board has traces to deliver the signals to the appropriate pins for different size chips. Maybe http://www.picall2.com has more concrete information. (My PCB is mounted on a stand so I can't see the traces. Obviously, 40-pin PICs use the whole socket. 8 pin PICs put pin1 on pin3, 28 pin PICS put pin1 on pin1, and my 18 pin PIC goes at the bottom of the socket.) -Matt -- http://www.piclist.com hint: The PICList is archived three different ways.

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 There are two different schematics for the P16PRO: one with the connections for an 18-pin socket, and one with the connections for 8-, 18-, 28- and 40-pin sockets. The latter one is the one that appears to be the most common - DIY Kit #96 (There is a kit of the 18-pin version). The GIF schematic posted to the PICALL website seems to be for the 18-pin version - which was, I beleive, the source of the initial confusion for Gilles Auger. The PDF schematic is for the version that handles PICs up to 40 pins - the Kit 96 version. - -Randy Glenn If you have to ship styrofoam, what DO you pack it in? ================================================= Randy_Glenn-at-tvo.org - PICxpert-at-picxpert.com PICxpert-at-yahoo.com - PICxpert-at-home.com http://www.picxpert.com/ ================================================= - {Original Message removed}
