  • OLED-96-G2 with Arduino Mega Images won't display

    I have an application that needs to display images on queue from code from an Arduino Mega. I have loaded the images and pasted the code as per the documentation through Visi. Thirteen images, one per form, thus thirteen forms. However, a simple test program, included below, to swap between at least two of the images, does absolutely nothing. What am I missing here? I have made sure the wiring is correct as well, i.e. "RX" from Mega goes to "TX" on the screen, etc. Bottom line, it just keeps displaying the last picture. pic13 form 13.

    Arduino Mega test code:
    #include <Goldelox_Const4D.h>
    #include <Goldelox_Const4DSerial.h>
    #include <Goldelox_Serial_4DLib.h>
    #include <Goldelox_Types4D.h>

    #define DisplaySerial Serial1

    Goldelox_Serial_4DLib Display(&DisplaySerial);
    int reset = 4;

    void setup() {

    void loop() {

    Display.media_SetAdd(2, 0x4600);
    Display.media_SetAdd(0, 0x0000);
    Display.media_Image(0, 0);

    Hi dtmacdonald

    If I get your question correctly, you want to display images loaded unto the microSD card (inside the Display Module) and the commands to change/display the images are coming from the Arduino Mega via serial comms?

    The code that you made in Arduino Mega is for the Serial Environment and not for the ViSi Environment.The ViSi environment is for using the Display module as a standalone microcontroller, or you can create subroutine functions that will be executed when it receives serial commands from the Arduino Mega.

    As a solution to your problem, and also because the code you made in Arduino Mega is for the Serial Environment, the implementation for this is different, you can learn more about that through this application note:

    I hope this helps.
