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

Move to refs:

 *  https://dev.w3.org/html5/html-author/charref

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

Zephyr app Driver out-of-tree
demo (app)
   ¦
CMakeLists.txt  <- set toolchain variant and toolchain path
Kconfig         <- refers to Zephyr top level Kconfig
west.yml        <- chooses SDK, driver projects (1)
driver
   ¦
drivers/
dts/bindings/
include/
zephyr/
CMakeLists.txt  <- · add subdirs when given drivers enabled,
                      · add include dirs holding header files
Kconfig         <- · refers to Kconfig in child 'drivers' directory
README.md


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

^ 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$'
