Motion led controller application runs on Ci40 board. One MikroE board acts as awalwm2m client having a clicker which detects motion. Controller application acts as awalwm2m server and observes any changes in lwm2m object registered by client on server, and whenever there is a change, controller gets a notification for the same, and glow led for 5 seconds.
| Object Name | Object ID | Resource Name | Resource ID |
|---|---|---|---|
| "Presence Sensor" | 3302 | "IlluminanceSensor" | 5501 |
Prior to running motion led controller application, make sure that:
- Awalwm2m server daemon(awa_serverd) is running.
- Awalwm2m bootstrap daemon(awa_bootstrapd) is running.
NOTE: Please do "ps" on console to see "specific" process is running or not.
Motion-Led Controller documentation is available as a Doxygen presentation which is generated via the following process.
-
Install Doxygen :
sudo apt-get install doxygen -
Generate the documentation:
$ motion-led-controller: mkdir build $ motion-led-controller/build: cd build $ motion-led-controller/build: cmake ../docs $ motion-led-controller/build: make docs
The output can be found in the build/html directory and viewed by opening index.html with your web browser.
Please refer OpenWrt-SDK-build-instructions for exact build instructions.
Motion-Led Controller Application is getting started as a daemon. Although we could also start it from the command line as :
$ motion_led_controller_appd
Output looks something similar to this :
