Old CooCox Embedded Pi - What can I do with it?

muman

Greetings from Switzerland! A first post, to see what happens...

I recently acquired a CooCox Embedded Pi (nice STM32F103 MCU) for almost nothing. 

The box has element14.com written on it, so I ended up here.
But it seems that CooCox no longer exists (I did find their old github archive, though).

Should I bin it, or is it worth playing with? (Remembering that life is short ;-)

Anyone done any nice projects with it?

Best Regards,
Matt

  • As much of a pack rat as I am... I'm going to recommend putting your energies into newer toys.  I going to guess that this isn't your first foray into microcontrollers so unless it piques a nostalgic vein... let it go.

    Hi kmikemoo. You are probably right! But I quite like the logic level translators on the CooCox board which allow it to work with 3.3V or 5V shields, nice for experimentation. And it has two sets of I/O pins - Arduino Standard + many of the other STM32F103 pins on parallel connectors. Other than that, the board is very similar to the STM32F103 Nucleo-64 board.
    I managed to get it working with Visual Studio + Visual Micro with full debug support and also with the Arduino IDE, via an old ST-LINK/V2 box, but I had to make an SWD adapter for it (I mislaid the ST-LINK cables in the mists of time). The STM32 Arduino libraries for the "STM32F103 Generic" device seem to work too, with some minor adjustments for the pin numbering.

    So maybe I won't bin it after all...

    If anyone is interested I could make a post with all the details.

      Laughing So you chose the red pill.  Good on you!  It's always rewarding to breathe new life into some of the older toys. Thumbsup

    From time to time, the e14 Community will have a competition on upcycling or reusing some older equipment.  This may be your CooCox's destiny.  Just something to keep in the back of your mind as you continue to work with this board.

    Everything works! USB CDC too :-) The only problem is the 3V3 regulator is max. 150mA - it doesn't say that in the docs, but I have a solution.

    I'd certainly be intersted in a post detailing the process you came up with to get board up and running using Visual Studio, etc...

    Hello again, Sorry for the delay. Everything works, CooCox Embedded is programmable with the Arduino IDE and with Microsoft Visual Studio. One or two "problems" though. I've added an [over-detailed] exposé of the CooCox board to my blog. No sure if I'm allowed to put links in the replies, but I'll give it a try...

    Is this too big for an element14 post or the upcycling competition? I suspect it is...

    OK! Here (after many adventures and rabbit holes) is my 'upcycling' exposé. 
    The Embedded Pi works well with the Arduino IDE and with MS Visual Studio.
    But you do need an ST-LINK box for debugging and downloading. 
    Unfortunately the post is rather big, so it's only here for now...
