Ergonomic, split and other weird keyboards

Rules

Keep it ergo

Posts must be of/about keyboards that have a clear delineation between the left and right halves of the keyboard, column stagger, or both. This includes one-handed (one half doesn't exist, what clearer delineation is that!?)

i.e. no regular non-split¹ row-stagger and no non-split¹ ortholinear²

¹ split meaning a separation of the halves, whether fixed in place or entirely separate, both are fine.
² ortholinear meaning keys layed out in a grid

Underglow in ZMK on Seeedstudio Xiao BLE not working (self.ergomechkeyboards)

Hey all.

I am currently prototyping a keyboard with the Seeedstudio Xiao BLE (nrf52840). I configured the shield config correctly & got it working. However, my RGB won’t turn on (followed the ZMK documentation on RGB underglow)

Does anybody have a pointer to a project that got RGB working with Seeedstudio Xiao BLE & RGB?

See my other response for how I am driving the LEDs :) (Works fine with an Arduino program so that is not the issue here)

It seems to me that I get this line wrong: NRF_PSEL(SPIM_MOSI, 0, 16). I would read this as "Set pin P0.16 as SPI MOSI", however I cannot find a pin P0.16 exposed on the Xiao BLE https://wiki.seeedstudio.com/XIAO_BLE/

Can you give me a pointer where I am wrong?

(my RGB pin is P1.11 / D6, so I would've assumed that I should change this to NRF_PSEL(SPIM_MOSI, 1, 11), I know that the use of low frequency pins is discouraged by ZMK docs)
