I just received my new 5'' screen for a new project and as soon as I connect the TX and RX from the touch screen to pins 0 and 1 of the MEGA nothing happens... I have just a simple code that shows on the serial monitor what message is received when a button is pressed in the touch screen and it works just fine with an Arduino NANO.
I noticed that the TX led on the MEGA is always ON even when touching some buttons on the screen and on the NANO the RX and TX blink when I touch the screen.
I have tried almost everything, I have no more ideas, anyone has some suggestion? maybe something to do with NEXTION library??
Thanks in advance
