Ed Wios on Github has done the hard work: https://github.com/edwios/nRF5_WS2812B go there and grab that repo.
Head over to Nordic and grab the SDK 12.1.0 download from here
Direct link (hopefully): https://www.nordicsemi.com/-/media/Software-and-other-downloads/SDKs/nRF5/Binaries/nRF5SDK1210.zip
Put the nRF5_WS2182B folder in the ~/examples/ble_peripheral/ folder
Open that folder in VSCode and execute the make command via the cli in the ~/pca10040/armgcc/folder, which will eventually produce the below .bin file
After modifying the code to suit the Llama Ta-Dama board i Can verify that the ws2812b works as expected.
