28 pin DIP 32MX Chip
Hi...Is there a hex file for the 28 pin 32mx chip..The link just gives me a page full of numbers ,,,I need a downloadable hex file to use with pickit 3...Also why are the 32bit boards all commercially made units..What happened to support for hobbyists..I would like a simple easy to make single sided board for the 28 pin chips similar to the 18F2550 one...

Hi griffo

We are currently working on a home made 32MX board with 32MX250F128 Dip chip. Of course this low cost Microchip DIP version should be the next Open Hardware to be compatible with Pinguino IDE. Bootloader is already compiled for this chip, just have to design a nice board to publish it.....

I'm guessing there will be several, perhaps many, such chips. It may matter which one. Expecting a volunteer project to provide ready-built hex files for each chip is a bit optimistic!

You can build your own bootloader as Microchip provide the files. Might be the best plan.

Hi jp,

I have a PIC32MX220F032B DIP ready with breadboard connection.
Could it work with your bootloader or can you/I modify it little bit so that I can try it with my board(breadboard connection)?

I am very happy to hear you work with MX250 DIP,which I was eyeing for a while, as it comes with 128KB and even less than 18f2550.

All,

btw, any idea, programming pic32 with pickit2?

I am presently trying this utility...

pic32prog works, apparently.

Olimex have a variant of the MX220 on their new board so maybe you could use their bootloader, though I think you'd need the same user button.

Would like to share:

MX220 breadboard connection (will start if bootloader available Big Grin)

First time in my life, I designed(of course based on Pinguino wiki) and made this board(18f2550), a smallest pinguino I guess Cool (testing on going)

Hi John,

is it available for windows?

I checked and it looks like it is available only for linux.
unfortunately, I do not have Linux now.

No idea - I avoid Windows like the plague!!

(Got fed up of the spam, viruses, blue screens, driver hassles etc.)

Let me know if I can help.
I've already asked for samples, and I'll probably try to design a new board from the current mm8.

Hi guys

The MX220 board from Olimex works with a PIC32MX220F032. So the bootloader we compiled ( Regis and I ) should work as is with your board. The link below is a modified version of the Microchip bootloader. This version works with the MX220 board ( The OLIMEX board ). It can be compiled with MPLABX 1.0.

https://docs.google.com/open?id=0B8a48f1...Ymt6M0FMdw

Of course if you need some help, just ask !!

JP

( just change the extension to .tar.bz2 , google docs don't accept zip file ).

That would make a very interesting tutorial..How to build your own bootloader....Maybe someone knows about such a guide
