Hello,

Thank you for posting on the forum.

You can check for ttyUSB0 to know when a display is plugged in.
To further confirm, ask for a module type or version number (please see commands in the manual) and check the display's reply.

I hope this helps.

Thank you,
Raquel

This file is specific to your GTT unit and therefore is not downloadable, or something you can just copy to the unit. B...

Hello,

Thank you for posting on the forum.
Yes, GPIO3 controls the motor and GPIO2 controls the amplifier power (there is a minor error in manual, will have this corrected).
Please note motor is active low, and amp power is active high.

Hello,

Thank you for posting on the forum.

I am sorry for the delayed reply.
I understand that your issue had moved to a different problem now (as I correspond via email).
For posterity, your GTT maybe having touch calibration which could be caused by a misbehaving SD card.

Hello Polina, Thank you for posting on the forum. As per our last chat conversation, I have been corrected: For the rectangle, triangle and circle buttons, what is referred to as 'foreground' is actually the text color. There is no changeable background color property, as the background is actually ...

Hello,

Thank you for posting on the forum.

Are you able to take the LK202-25 out from your system and power it separately?
Try installing manual override as well. If manual override clears the issue, make sure to save the settings.

Please let me know how it turns out.

Thank you,
