Backlight flashing on XD75 #3555

Closed arpinfidel closed 6 years ago

arpinfidel commented 6 years ago

Hi, I'm new to qmk. I'm trying to add backlight functionality to my XD75 but when i enable backlight in rules.mk, the backlight just keeps flickering. Using BL_DEC eventually turns the backlight off but other keys don't seem to work. This seems really similar to a previous issue. #2226

I tried checking whether it's the same problem or not but this time the parenthesis is fine.

I got around the issue by using the keycaps_led_on and off from xd75.c but these don't allow me to change the backlight brightness. Is there some other way to have brightness control?

update : BL_INC and BL_DEC now work after undef ing BACKLIGHT_BREATHING. however the leds flicker and BL_TOGG still doesn't work.

update 2 : wiped eeprom. found out that flicker stops when underglow isn't set to breath. BL_TOGG can turn on backlight but not off. didn't test this before wiping.

have you seen this reddit post already?

ooh thanks. i haven't actually. only searched on r/olkb lol. that one is about the same thing as issue #2226 though. it was fixed a while back.

i found another issue similar to this even on a supported pin #3566 and the flickering is apparently documented already so this should probably be closed.
