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

^ 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$'
