I found the problem, the USB-C cable does not work, I have 4 USB-C cables, there is only one that works correctly.
The problem is solved.

THANKS.

@teastain2 All right. I'll try. I was hoping that maybe someone here had already encountered this problem and could help me.
Thank you.

@elitesniper Well, there is a blown component, probably the 4065 charge chip.
SMD repair is very tedious and needs special tools, solder and liquid flux.
Do you see any burnt chips?
If it works on USB...go with that!
A external battery with 5V regulator will work.

@swerwe123 I solved it with @RobLatour 's help. Glad to hear it helped!

@fozi said in T-HMI Screen Rotation 3:

https://github.com/Xinyuan-LilyGO/T-HMI/issues/7

I fixed the issue.
In file: "Setup207_LilyGo_T_HMI.h"
Located in: \libraries\TFT_eSPI\User_Setups

Either remove or remark line 11 "#define CGRAM_OFFSET"

After making that change all rotations orientations work.

@tolisn Good job! This is a modern headache. LilyGO recommend ESP32 board version 2.0.15, which I use.
The new board defs are for newer C6 chips and other new Bluetooth chips.
I hope it settles down soon, it is tedious.

@teastain2 Thanks for the information. Will certainly check on them. Thanks again.

Good morning,
I'm a newbie on this king of sfotware development and I just wanto to do an project with a several screens on lilygo t-rgb 2.8'' to control 2 servo motors but my screen remains always black... I already tried almost everything but maybe the problem is my waek knolegment about this area...
Can you share with me a simple project working with SquareLine Studio and Arduino IDE?

Thank you for you help

@jxk Ok, then.

Did you copy the zip file from this location and then copy the contents of TFT_eSPI folder into and overwrite the existing stock arduino TFT_eSPI libraries?
Very Key!
Then try and load the FactoryTest that is inside that folder.

@danteypl Your only choice is to contact

Thanks, I realize that I can change the definitions of Wire to the other pin, but then would the Touch display not function appropriately?

I would prefer to define GPIO2 and GPIO3 as Wire1 and not Wire, and have the touch display use that interface. I would then define Wire as the new pins (as per your example above).

Is there a software option to do this? I am using some libraries that are hardcoded to Wire, and don't want to manually change them myself.

If not possible, the Mutex method around the lv_task_handler() seems to work well - the board has been running for about 2 weeks with no issues, and no bad data.

@llsummer You should use ESP32S3 Dev Module, it seems.
If you have an issue with that advice you know very well where the LilyGO LilyGO T-Display S3 GitHub repository is.
Make an Issue.

@jimbrown-net Niiice!
