I have the board part built and just wanted to do some testing before I connect the high power devices like the light and motor.I have the SD card, the micro and the screen all connected. I have an SD card with one file Magic Rays of Light.wav fitted.
I turned the unit on and get leds on the mirco and the LCD lights up (TX connected to TX). I was expecting the display to show something other than the default screen. I tried pressing reset and got no change. Is there something I am missing here? Should the "custom" display be working at this point? I have not added firmware as you supplied it with firmware on from memory.

I don't know why but I tried uploading the nbtv3.tft file as TFT means screen. And viola it updated. I dunno what that HMI is for.
Next the touch didn't work so I connected RX to TX versus what I had which was TX to TX and the screen can find the sd card files.
Cool... now I can move on to the next stuff!!!!
