Hi All, I recently for myself a Lily 58 with a mikoto chipset and i have set it up with ZMK.. however I am unable to get the display working.
here is how my .conf file looks like

# Uncomment to enable encoder
CONFIG_EC11=y
CONFIG_EC11_TRIGGER_GLOBAL_THREAD=y

# Uncomment the following line to enable the Lily58 OLED Display
CONFIG_ZMK_DISPLAY=y
# CONFIG_ZMK_WIDGET_LAYER_STATUS=y
# CONFIG_ZMK_WIDGET_BATTERY_STATUS=y
# CONFIG_ZMK_WIDGET_BATTERY_STATUS_SHOW_PERCENT=y
# CONFIG_ZMK_WIDGET_WPM_STATUS=y

I have the widgets configuration commented out because the pipeline to build the firmware fails when i have any of those lines enabled.

Any help would be appreciated to get my Oled displays working again..

😅 I didn't see this post before replying in the other, sorry about that.
Please link your repository. Kconfig options can be configured at multiple locations and it's easier to see everything including build logs.

The correct name is CONFIG_ZMK_WIDGET_BATTERY_STATUS_SHOW_PERCENTAGE

But I always had ‘CONFIG_’

calm quail Mar 20, 2025, 10:22 AM

#

With and without CONFIG_ refers to the same option. The build system uses two vairents in different places.

CONFIG_ZMK_WIDGET_BATTERY_STATUS_SHOW_PERCENTAGE in .conf files is ZMK_WIDGET_BATTERY_STATUS_SHOW_PERCENTAGE in Kconfig.* files.

You were using ..._PERCENT, not ..._PERCENTAGE

sorry, none of these helped.. i do not have nice_view_adapter or nice_view in my build.yaml..
There is no issue with the power delivery because when i flash with the default config, the display works..

#

i am getting the default firmware from here

#

Are you using the one "with display" or "without display"?
The "With Display" is built for a nice!view, which is not an OLED.

#

Does your display have four or five pins?

#

sorry if i am being ignorant, these are the options i am choosing. i have a lil58 with mikoto controller and OLED display

hot ocean Mar 24, 2025, 7:21 AM

#

its got 5 pins

calm quail Mar 24, 2025, 7:25 AM

#

Yeah that's a nice!view, not OLED.
i2c OLED screens have 4 pins.

#

128x32 i2c OLED display (random image I found)

This is their build.yaml https://github.com/keebd/zmk-firmware/blob/main/lily58/lily58.yaml

#

shield: lily58_left nice_view_adapter nice_view should work for you

hot ocean Mar 24, 2025, 7:47 AM

#

ok that did it, thank you. can you point me so some documentaion that i can refer to configure the diaplay?

calm quail Mar 24, 2025, 7:51 AM

#

Do you mean configuring the content displayed?

#

There's no option for configuring the content. You can swap the nice_view shield to something else, or write your own display in C.
