    Color OLED SSD1351 driver testing

    Sukesh

      Driver for 1.5" color OLED using SSD1351 is available now.

      upm/src/ssd1351 at master · intel-iot-devkit/upm · GitHub

       

      Its not working for me with the Densitron module I have.

      Anyone here can test it for me if you have a Color OLED which uses SSD1351

       

      Not sure if it works with the Freetronics module or not.

       

      My older thread on this topic is here

      Intel Edison + 1.5" Color OLED using SPI - SSD1351

       

      TIA

          Hi Sukesh,

           

          I would like to know more information about the problem you have.

          1. Which image are you using?

          2. Which expansion board are you using?

          3. What is the error message you are having?

          4. Which UPM & MRAA libraries versions you have?

          5. Which example are you using to test this?

          I checked your other thread, have you been able to test the SPI signals to identify the problem (frequency, magnitude, noise, wrong data..)?

          Please let us know how you are testing this.

           

          Regards,

          Charlie

              Thank you for the follow up Charlie.

              I am working with an Intel resource offline on this but to answer your questions

               

              1. Which image are you using?
                  The latest available publically over here for download

              2. Which expansion board are you using?
                 The board is a custom designed board which has more components as well.

              3. What is the error message you are having?

                  I was getting kernel panic as well as nothing shown up on the display

              4. Which UPM & MRAA libraries versions you have?
                  Latest public version available.
              5. Which example are you using to test this?
                  Using the same sample provided with the driver.

                Hi Sukesh

                 

                Do you want to continue using this thread or can we marked as resolved?

                Please let me know if you are going to work with the offline resource instead of using this thread.

                 

                Regards,

                  Thank you Charlie to response.

                  Yes we can close this thread.

                   

                  We got the display working by changing the SPI mode setting in the driver to SPI_MODE0 instead of SPI_MODE3.

                  m_spi.mode(mraa::SPI_MODE0);

                   

                  Hope that helps this thread.
