Tinypilot. Turn on screen backlight via GPIO. - kaa39518 - 2021-02-15

With a long hold on the "Menu" button, turn on the backlight connected to the GPIO contact.

Sincerely, Alexander.

the backlight is adjustable from the menu already. There is even a light sensor for it. What are you trying to achieve?

Do you want backlight to turn on with buttons pressed?


RE: Tinypilot. Turn on screen backlight via GPIO. - kaa39518 - 2021-02-16

Yes. So that you can turn on and off the backlight with existing buttons.
I do not want to install an additional arduino and light sensor.
Is it possible to do this?
With respect to the work done by you!

So far it looks like this.

It remains to deal with the backlight Smile

making your own pcb? amazing!

you need it to somehow toggle io pin from keys? It is possible to do with small changes to the display program.

The case was printed on a 3D printer. A keyboard on a laser printer on a film. The board was engraved on a CNC milling machine. Smile
