Zephyr Driver and Separate Demo

- OVERVIEW - Here list and begin to describe key, salient features of a Zephyr RTOS based driver and separately build-able demo to exercise given driver. Driver for first version 0p0 is "out of tree", in other words outside of Zephyr project's source tree.


^ Key Zephyr App Files

Key files in the two parts of Zephyr out-of-tree driver and demonstrating app:

Zephyr app Driver out-of-tree
 demo (app)
    |
 west.yml        <- chooses SDK, driver projects (1)
 Kconfig         <- refers to Zephyr top level Kconfig
 CMakeLists.txt  <i><- set toolchain variant and toolchain path</i>
driver
   |


All the more that is in Jared Wolff's AQW demo:

ted@localhost:~/projects/embedded/ncs/zephyr/samples/sandbox-de-ted/jared-wolff/demo$ tree -R

2 directories, 11 files


^ Useful Commands To Manage Details

Command available on Ubuntu hosts to effectively locate Zephyr RTOS project installations:

   ted@localhost:~/projects/embedded$ locate VERSION | grep 'ION$'
