Backlight? #7

Open qewer33 opened 1 year ago

qewer33 commented 1 year ago

I was wondering if this board really has a backlight or not. The reference image in the store product page mentions IO33 as "Backlight" but below code does not seem to work:

#define BACKLIGHT 33

pinMode(BACKLIGHT, OUTPUT);
digitalWrite(BACKLIGHT, HIGH);

Does this board not have a backlight or am I doing something wrong? Thanks in advance!

There is a connector in order to connect a backlight. But the backlight itself is not included.

Do you know anywhere one might find a compatible one?

It seems that the connector is compatible with the "front-light" GooDisplay (small flat cable). The e-paper display + front-light is available on Aliexpress : https://fr.aliexpress.com/item/1005006277614640.html (not tested)
