    Oh... and a second issue.

    I made a reset for the display but it does not working. I use an UNO for testing the code and I use the 5th pin for reseting the display via UPA reset pin.

    This is the code fragment which has been integrated to the end of the setup.

    pinMode(5,OUTPUT);
    digitalWrite(5,LOW);
    delay(4);
    digitalWrite(5,HIGH);

    Big THX.

      Hi Peter,

      I just tried your project using the terminal to send values eg 1,8 - 2,8 - 3,8 - 4,8 and it worked fine. Could you please let me know what SD card you are using.

      Best regards

      Paul

        Hi Paul,

        I appreciate for your quick answer.

        I am using the original card which has been sent with the display.

          By the way. When I use the terminal than it works fine. It just happens when the data comes from the Arduino through the Rx/Tx line.

            Ok, I'll rig up a constant test to try to replicate here. Hopefully I will get the same issue and be able to update you with a solution.

              Hi Peter,

              I haven't been able to replicate the error. Mine has been running for hours without corruption. When the corruption happens, does it return to normal after a reset ?

              Best regards

                Hi Paul,

                It is interesting because I have started the system today in the early morning and it does not do this so far.
                The only one difference is I have chaned the microcontroller for a bigger one. Originaly I used Atmega 328P and now 2560 type.

                But answering your question when this phenomenon happened then the reset not solved the problem.

                I do not know why it is happens however would be good to know the reason why.
                Ok, if it happens again then I will let you know. :-)

                Thank you very much for your very kind help.

                Peter
