wrong screen color

[monfiston]

hello
i have 2 openEVSE, one official and one tinkered by myself
the color of the screen is not identical on the 2 openevse,
is there a way to change the color of the screen?

Is the LCD an OpenEVSE LCD on both?

No, it's not an original screen, but I thought that in the past you could choose a specific color?

The LCD colour is linked to the EVSE state. As it is lighting up and displaying text it must be the same driver chip, but I assume the RGB backlight is connected to the driver in a different way (I think the red and green are swapped). So for proper operation you will need to do a custom version of the OpenEVSE that corrects for this.

hello
it is not possible to change the connection to the rgb led?
if not, what should I change in the code?

You probably want to redifine https://github.com/OpenEVSE/open_evse/blob/master/firmware/open_evse/open_evse.h#L640-L646 to the numbers that match your display
