Hi Dany

the comptimer.hmi adapt to your screen! (400x320)

Then the comptimer.tft  <--- !!!         uploaded via a sdcard on the screen.

sketch in your mega load

TX2 and RX2 on your mega

display TX -> mega RX2

Display RX -> mega TX2

this works for me!

Hi Vic

Yesss does it work

but my tx = screen must be connected to mega tx2

= rx screen is mega rx2


I do not know why I have to try to understand the rest and my heating and humidity control project going to start

I think I made the right choice for a touch screen that I see

thank you very much appreciate your help

Graag gedaan

you're welcome

greeting Vic.
