Pinguino mp8
Hi All,

Just as I said, this is the project I'm currently working on. My goal is to get a standard Pinguino board that can hold either PIC18F2550 or a PIC18F4550 with Arduino form factor...

RE: Pinguino mp8
Hi dip6, nice idea...

I'm not EE but I like to make 3 remarks:

a) Even if you end up with 2 different PCBs (1 for 28pin and other for 40pin), move forward with the idea... it looks good...

b) Allows for the use of sockets (for MCUs), I think that the idea of "hacking" (replacing, changing MCUs) is nice...

c) Having this 8bits-dual in Uno Form Factor will help a lot the project to attract people...


Open Source Hardware brings more power and more challenges than OSS, but I hope you can find a way to make the project files available to the public, in such a way that it also be rewarding for yourself.

Regards.

Hi Valter,

Of course, it will be OSHW and it is an "open" project... so questions & comments are welcome. It seems to be easy, but I have some doubts about pin assignation. As soon I have my first attempt I'll share with you here to discuss it.

Cheers.

Pinguino mp8
Pin Mapping

Hi again,

Here is a comparative table with several pin mappings (Standard Pinguinos, JAL, PICuno) and my Pinguino mp8 first pass mapping:

My only concern is about PWM pins. Obviously, there are not enough PWM pins and some shields are pin dependent. Maybe a microswitch could be helpful...

Of course, I'll add additional (to Arduino standard pins) headers for the 4550 "extended" pins.

Very interesting idea, so this board is for use one time 18F4550 or 18F2550, but not both at the same time.

Could be a posibility to make them work together? (I'm just letting flow my fingers) For example this could be done to have something like PINGUINO-DUAL CORE?

It sounds great... but I'm afraid the answer is no. We could "share" a board for two micros, but I suposse the only shared resources would be power, ground and the PCB itself...

Also you can share the 20MHz crystal, and the reset button.

There was an inconcluded project around the web called: Core2duino
http://www.instructables.com/id/Core2duino/step7/Enjoy/

But it's devolopment stops at 2010, the main reason was the release of arduino mega (more pins).

Very interesting, but that was not a "dual core" but a "dual head" Smile

Yes, you're right. Currently I'm going to develop a project using pinguino and I want to use the CDC functions, but the code is very big, so I will need another pinguino conected in the same board, and seems that the best way to connect them is via I2C, because this permits to connects more devices in the same bus.

RE: Pinguino mm8
Anyway, this is the first "draft" I have at the moment:

[Image: mm8002.png]

Yes, the project's new "code name" is now mm8.... (multi micro 8 bits).
