Post by thread:PIC16C84 programmer

Hi; I have joined this group about 10 days ago. I have just purchased my first PIC16C84, together with a couple of other components and a PCB, with a bit of prototyping area (mail order; in Japan). Now I need a programmer! I found a couple of programmer packages (schematics+software) over the net, and will build one of them myself (we are short of cheap PIC programmers in Japan!). The most important criterion for me is reliability, so that I don't have to decide whether it is my code that is wrong, or the programmer is acting up!(experience from a home brew EPROM programmer...) A decent user interface is necessary here; not the colorful Win95 type thing, but one that tells me what is going on clearly (DOS preferred, but anything is fine-UNIX,MAC). Given this short background, can someone suggest a "the best" design among those available over the net for free? I have been making circuits for about 15 years, about 7 of them with microprocessors; so design complexity is not an issue... Well, what do you people suggest? Thanks; | Ahmet ONAT Kyoto Univ.

Hi! I posted a request for suggestions about which PIC16C84 programmer to build. I have already received a couple of mime encoded (LARGE) files. While I am thankful to those who take the trouble to send the files, I would appreciate a discussion of which setup is better than the other, and pointers to where they can be found! Otherwise, I will have to build all the programmers to see for myself if they work properly or not! Thanks; | Ahmet ONAT Kyoto Univ.

Those who connects to the serial port and those who connect to the parallel port of a PC. The serial port type is simpler and uses the port signals for its programming voltage. Since not all serial ports are identical and often the manufacturers uses lower voltages to save power (especially on laptops) you might get problems with a serial port programmer. A parallel port programer wont have this problem since it uses a external power supply but this is naturally more complicated. I use a serial port programmer myself and it took a bit of tweeking before I got it right. I found that it somtimes can help to use an external 5v supply (preferably taken form the gameport). Also I found that some PICs will program and some will not. /Pelle

I'm now using the Starter Kit supplied by microchip and the MPLAB software from the MICROCHIP site: http://motserv.indirect.com/home2/mothome.html I've also Explored a local ICE that includes an ICE hardware board using a PIC with dos based software. The also sell hardware and not software so u can look at the program for demo purposes.(Let me now if you are interested) This package also supports the typical 8051 Pseudo code that extends the PIC ease of programming. > be found!

I'm not using a modem link and I did not experience the problem myself before. My apologies for your time wasted. I'll keep that in mind to first send out attachments at request. Best regards Jattie.

Have a look at: http://www.labyrinth.net.au/~donmck There is the free circuit and overlay of a Printer port driven programmer based on the original design by David Tait. There are free software drivers that include a disassembler, and support for the following devices: 61,62,63,64,65,71,73,74,84,620,621, and 622. This design was introduced in Feb 95 and has the advantage of using a 4PDT switch to allow a Program/Run mode for the 84, so it will program an 84 in circuit in around 2 to 10 seconds. About 250 have been built up on a Printed circuit board I can supply, however I would think that many more have been bread-boarded by home constructors. Don...

The attachment that I've send to the PICLIST group Included the David Tait version with a few hardware and Bugfixes. The Guy who fixed them Robert Farrer from Farsoft Computers included David's Copy Right Notices and redesigned his hardware layout with Notes on the Fixes. For more Info you can mail me Directly. Farsoft is not available on the Internet but is on a local 14400 Modem Bulletin Board and I've Got most of their stuff on My PC. I've got a propoasl from several guys to make use of their FTP sites to uoload the software. I'll speak to Robert and see if we can arrange that. He's converted most of Microchips samplecode to run on '84's as he also does a course on PIC micro's wich is very efficient. People with no experience can learn in 6 weeks to be quite efficient programmers. Let me now if there's interest and I'll forward all the requests to him. Thanks. Jattie van der Linde.
