gnupic: Thread: Programming 18F parts from linux?

Hello all,

I have a micro engineering EPIC parallel-port programmer that I (mostly) 
successfully use to program 16F877 parts with, using a modified version 
of picprg 2.3.

But now I'm on to 18F parts (specifically the 242 and 452) and need to 
program those.

I'm thinking of going the bootloader route to simplify and speed up 
things, but I need to program them at least once to start with, of course.

The (windows) software that came with the EPIC requires and upgrade to 
handle them, which I can only get by mailing them the original floppy, 
plus $10 plus UPS shipping back to me.  Utterly absurd.  It seems they 
think its still 1985.  I'm doing it anyway but will probably be 2 weeks 
before the precious floppy disk arrives.  So I can't take the bootloader 
approach yet.

How are people programming these parts?
Anyone using a parallel-port style programmer, with source for the 
software so I can patch it to use the EPIC?

Thanks in advance!
Jesse

Hello,

I'm using PIC18 devices and a personnal programmer (hardware + software)
under Windows to access the chip.
The PP18 programmer is distributed under GPL license and the code is
available on my web site :
http://perso.wanadoo.fr/softelec/

A Linux version will be quite soon available too, but I need to complete it
before updating my web site.

I hope this will help you to program your chip.
CU
Xavier

Hello to all. I have modified Brian Lane's code - picprg - and add some code to program pic18F452 (program memory, eeprom memory and configuration bits) - without verification, but I think it programs quite well for time being - read these areas of the chip and bulk erasing. I don't 
have my own place (web site or anything similar and i don't have the time to get involved with) so if anyone is interested just send me a response
and i 'll  upload the code with email. The code is not documented very well so i'll be glad to get any remarks. Greetings..

Thanks,

I'd really like to get a copy of that code. I'm an active developer of picprg
and have make several significant updates to it.

Also I'll happily host it on my PIC page: http://www.finitesite.com/d3jsys

Please let me know,

BAJ

Hello BAJ. You can download the code of picprg - with pic18f452 patches - from the locationhttp://morgoth.tlc.upv.es/~hecormar/pic18f.The code is not very well documented and optimizedbut so far I think it works. Another important thing is that you must define the configuration bits 'setup' from within your assembly code. An example that I have tested and works is at the same URL.If you have the time and ...patience to have a look at the code please let me know your opinion and any observation or remark is wellcome. Bye!
