Hi, I have connected my tft 35 v2 to my skr mini e3 v1.2 with marlin 2.0, but the screen doesn't show anything, it's on but nothing is showing. I have followed the right wiring and still nothing. Any help will be great Thank you

Set in config.h

define SERIAL_PORT 2

define SERIAL_PORT_2 -1

Update the firmware for TFT

If you have it correctly wired up, it should work

youneslak commented 4 years ago

Thanks you @rydol Is there a way to update the firmware even if the screen is not showing anything?

rydol commented 4 years ago

@youneslak The screen should light up with its basic menu if its wired correctly. Even if you just power it up with 5v. Then you should see message: printer connected or no pritner connected at least. How did you plug it to the board ?

youneslak commented 4 years ago

@rydol I have connect it just like this wiring scheme 68256273-7c5f4680-0094-11ea-94aa-ca037c216403

but still the screen is just blank no menu or anything

@youneslak Seems good to me, what happens when you connect only 5V and GND ?

youneslak commented 4 years ago

I haven't wired it with only 5v and GND. I thought that it has to work directly without any problem, since i brought the motherboard and the tft as a pack.
