  • Somo II microcontroller

    Hello,

    a question about the 16 bit microcontroller installed on Somo II. Is it manufactured by 4D Systems? Is the firmware available after device purchasing?

    Regards,
    Vito

    Hello Vito

    It is not a 4D processor, no. However the firmware was customised to our requirements.
    Is there something specific you are needing, or is there a problem?
    From memory, I believe the firmware is OTP, so its not something that can be changed after its produced, but I will confirm this after I hear back from you.

    Regards
    James

      Hi James,
      thanks for your reply. Actually my question was for curiosity.
      I purchased the module yesterday, I'll expected it for next week.

      Regards,
      Vito

        Another question:
        Is there any application note ( for example providing a code) with a host microcontroller which is connected through serial port to Somo II?

          Hello Vito,

          What type of microcontroller were you thinking of, We have a library which uses it's own version of a software serial TX for aduino on any digital pin. It will not poll any info from the SOMO but will send all function's to the SOMO.

          Is this the kind of thing you are looking for ?

          Best regards

          Paul

            Hello Paul, I'm looking for a library for Arduino (XXXX.h) which would allow to send AND receive infos to and from a SOMO-II I purchased recently. Or alternatively, a procedure how to get replies from queries.
            I found a library called SOMOIoD but can't find any list of the commands included.
            Regards,
            Claude.

            Hi Claude,

            The SOMOIoD is a one pin library so as you probably noticed you cannot query the SOMO.

            There is this library on Github for the SOMO-II which does support querying the device

            https://github.com/DefProc/somo-ii-lib

            I hope this helps

            Best regards

          I was thinking about Microchip microcontrollers.
          can .wav files be reproduced using the somo II? I guess it's not possible...

            Hello Vito,

            The SomoII will play mp3 and wma files only. wav files can be converted to either format for playback.

            Best regards

              Hi Paul,
              i'm using the module; my application should be able to play mp3 and wav files inserted in the SD card. I noticed that actually the wav files I inserted in the sd card, to perform a simple test, are played for a few seconds before the module stops. It's a strange behaviour, I thought it would have totally ignored .wav files. Can you have an explanation for that?

                Hello Vito,

                It's surprising that it attempt's to play the wav file, they are not supported hence probably why they stop after a short time. It may be something to do with the size of the wav file compared to a mp3 or wma file.

                Best regards

                  Hi Paul,
                  I have another question: is it possible to query the module in order to obtain the list (and not only the total number) of files (songs) in a particular folder uploaded to the SD card? From serial command set in the manual I would say not, but I'm asking you just for a confirmation.

                    Hello,

                    It isn't possible to query the module in order to obtain the list, I guess it was not included as it would take a long time to send the list and the items would be different lengths etc.

                    I hope this helps

                    Best regards

                      Hello,
                      Is it possible to buy just the programmed SOMO II microcontroller?

                        Hello Marek,

                        Welcome to the forum!

                        May I ask what your purpose would be?

                        We don't usually sell the chip on its own.

                        If you want, you could contact our sales department at https://www.4dsystems.com.au/contact so they could discuss your options.

                        They may ask about your project's details like MOQ, project lifetime, etc... as part of their assessment process.

                        Best Regards,
                        Michael
