zephyr

As part of the work in #736 we added a Kconfig setting to keep using the old built in "nano" z_printf implementation, after identifying that our use of format strings didn't work properly w/ the newly introduced CBPRINTF in the newer Zephyr release.

Someone should back out that defaulting, and make ZMK work with the newer printf implementation.

See https://github.com/zephyrproject-rtos/zep

repo forall defines a useful set of environment variables for the duration of each call:

• REPO_PROJECT is set to the unique name of the project.
• REPO_PATH is the path relative to the root of the client.
• REPO_REMOTE is the name of the remote system from the manifest.
• REPO_LREV is the name of the revision from the manifest, translated to a local tracking branch. Used if you need to pass

The pinetime watch has a small motor to produce vibration. Let's imake it work !

The motor is plugged on the GPIO P0.16 of the NRF52. See image.

I guess simply driving low and high this GPIO would make it work.
We will need some kind of thread or timer if we want to make some spec
