    Hi Kuno, yes, the screen should clear first. This is starting to sound like the Teensy 4.1 board.

    I will look to see if I have another display so that I can recreate your test setup today. I will let you know what I discover.

    Hi Kuno, I found a display (I'm glad I bought a spare!) and it works with just the following connected:

    VCC to 5V

    GND to G

    CS to pin 10

    RESET to pin 8

    DC/RS to pin 9

    SDI(MOSI) to pin 11

    SCK to pin 13

    LED to 3V

    SDO(MISO) to pin 12

    If this is how you are connected, then I suspect a problem with the Teensy 4.1 board. Here is mine with only these connections.

    You might try re-loading the HW2 version (V002.003B4) from my post above, just in case there was a problem with the firmware load.

    Also, do you have SmartSDR running when you boot up the TeensyMaestro? If not, try it with SmartSDR already running.

    If none of this helps, then there is most likely a problem with your Teensy 4.1 board.

    Len,

    it looks like I have to get another Teensy. I also tried the latest Beta version and wired the same way you did, but without any change. Many thanks for your patience, it will take a while till I get the new Teensy.

    Hi Kuno, sorry that you had so much trouble. Hopefully a new Teensy board will be all you need.
