Embedded Pi

ss2410

Hi all, I’m quite new to this, so please bear with me.

 

I’ve got a Pi3 B and the Embedded Pi, I was hoping to use these with my old Arduino Shields for a few projects. Any idea where to get the information on running them if it’s possible(CooCox is no more) If it’s possible to use these together or will I have to get a Pi1 or 2?

 

I did find some examples but having a very hard time getting anything to work, I also have an Arduino Shield Shield from iTead which seems to be the same, ie no longer in production.

 

Any help would be gratefully accepted.

 

Steve

  • Hi Steve,

     

    I don't think it is a popular board, so it is likely you may be trailblazing getting it to work. In theory it isn't a lot of work, but would still take someone experienced at least half a day to trawl through the docs and schematics, to figure out how to use with the Pi, and provide some basic API in whatever language of choice, unless something already exists on the web.

    There was a small window when such a board might have had some use, but nowadays there are many HATs for the Pi, so maybe there is less demand for such an adaptor board. There is a list of more recent boards in the document here:

    Otherwise, if you need to connect a particular arduino shield, it may be quicker to just explore the shield and see what signals need connecting, and just patch them to the Pi using jumper wires. Level conversion may be needed in the Shield->Pi direction. In the Pi->Shield direction, sometimes level conversion is not needed, but it will depend on the shield in question.

    The shield may work well with the Pi, but sometimes timing matters - so it's not guaranteed that it is effective doing this or not without knowing more about the use-case, or the particular shield.

    I bought one of these a while back (many years) and was sorely disappointed. The board was designed to be only be programmed from Windows (which is a terrible idea for a Pi device) and Coocox have now vanished.

     

    After some significant playing around I managed to get some software running on it, but it isn't easy as you have to build everything yourself. This is not a trivial task!

     

    I was able to cross-compile on the Pi using the Pi's compiler with the appropriate flags. However, it needs customer libraries and all sorts of other complications making it very much one for the “enthusiast”. I may have another go at working on it but I'm thinking that using the Arduino programming environment may be a better starting point (they have some STM32F1 support in some unofficial github repositories).

     

    E14 really ought to warn people about this in the information section on the product.

     

    Regards,

     

    Jim.

    I had a play with one of these ages ago. I found it on the way to the rubbish bin still in the original packaging. I hunted around for a while and just this morning came across the schematic - was it always there???  This helps a lot - at least to verify the jumpers etc etc. I have been working with some stm8 and stm32 boards and if nothing else maybe I can get some stm code to run on it. I paid nothing for it but always thought that it would be a neat piece of kit but documentation was sadly lacking. I was unsure of the jumpers. Anyway we shall see what I do with it...

  • I have used a chipKIT Pi which might do what you are suggesting?

    Thanks for that. It looks cool. I am enthused with my existing board for the moment.

  • The DFRobot Gravity Pi to Arduino Shield might be another option for you.
