Invert option for TFT_LED

Question

maxl95 opened this issue 4 years ago · comments

First of all, this project is amazing and works like charm.

Now my question:
Is it possible to add an option to invert the backlight?
My backlight needs HIGH state to activate.

Stale

Hey,

thanks a lot.
Did you try this one yet in the config file? (See Hardware under Configuration: https://github.com/sieren/Homepoint#configuration )

"ledPinPullup"	Boolean	true or false - control backlight power which can be pull-up/down depending on unit

Thanks for your replay,

yes, I've already tried that. Unfortunately, the backlight is always off. I need to put the TFT_LED pin on VCC so that the backlight comes on.

If youre using the esp-generic build of Homepoint I could recommend checking the wiring schematics in the wiki: https://github.com/sieren/Homepoint/wiki/Hardware (linked at the very bottom)
