gnupic: Thread: Programmer

Hi,

Does anyone here want to help me in designing a 16f87x programmer for linux?

I want it to use the serial port; it must be low cost.

I may use a design like Tony Nixon's ASCII programmer.

Please email me if you would like to help.

The licenscing scheme may be GPL or Shareware(w/ source for devel purposes :).

Hi Andy,

Perhaps I can save you some time here.
There is a VERY good programmer available that is picstart plus
compatable, and as there is already software for Linux for the picstart
plus the problem is solved!!!

Have a look at this address for the "WARP 13"

http://www.new-elect.com/

I know around 10 people that are using this programmer (including
myself) and everyone has nothing but praise for it!

It is capable of programming PIC's, some ATMEL micro's, Serial EEprom.
In a WINDOZE environment they have a program 'warp13' that gives you
VERY good control over the programmer, unfortunately there is not a
linux version of the software yet, although any picstart plus compatible
software will work.
The programmer also has an ICSP connector on it to make life easier.

If you are using 3rd party software and doing ICSP it may be necessary
to connect pin 1 and 4 on the ZIF socket together depending on the
device type being programmed.  DON'T FORGET to REMOVE this LINK BEFORE
programming anything in the SOCKET!!!!!!!!!!!!!!!!!
I did this by linking pin 1 & 4 on an 8 pin socket (machined pin!) that
I place in the ZIF socket at all times while using ICSP.

Hope this is of some interest, and that I didn't jump in at the wrong
time.

Regards
David Godfrey

BTW::  I have no conection with this company, I just LOVE their
programmer!!!

There are a few designs around that use just a few components (a number listed at
http://home.att.net/~wzmicro/pic_link.htm).  I'm helping  James Kingdon with the
jpp877 software (http://www.kingdon5.freeserve.co.uk/jpp877/jpp877.html) so that
it supports a number of tait-style (parallel port) and serial port programmers.

I'll be writing a driver for Tony's ASCII programmer for jpp877 but be
forwarned: programming a '877 with the ASCII programmer (at 1200 baud) will be
really slow.  I'm mainly doing it because I've alread built the hardware so I can
use it to test my first driver for a serial port programmer.

Actually, if you look at:
http://www.new-elect.com/mac-linux%20page.htm
there is program source for a driver that runs on Linux!

A search from google using the keywords "picstart linux" yielded the site
http://www.cosmodog.com/pic/ .
Here you'll find 'picp' that claims to the linux software for the picstart
plus.

i'll read it and then let ya know what i think :)


ok  this is what i think...

i'll use a 16f84 as a serial-parralel converter. then i will make it
bi-di(enable tx thru a pin if i need the functionality :)

hows that sound???

alright?

Is there anybody on the list using warp13A. It was the best that I could 
afford. MPlab is not supposed to tell it froma pickstart+. I hope the Linux 
software react the same way. Any pointers would be great!

Hello all
Is there any schematics for hardware serial or parallel programmers for PIC ??
I want a simple circuit please.
And if you can point out which software works with it  !!
Note that I am using Linux

There is a cool webpage:

www.gnupic.org

See the Programmers link in the left panel.

You can Use Brain's TLVP for example.

Regards!

Thanks Gustavo
I was asking about something tried by anyone here, yeah, there are loads of 
links and programmers.
I wanted to know if someone here tried something !!

Declan, I know google, she is my friend ;)
As I said above, I wanted something tried.
