Button-Led controller application runs on Ci40 board. One MikroE board acts as awalwm2m client to simulate button. Controller application acts as awalwm2m server and observes any button presses on MikroE board, and whenever there is a change, controller gets a notification for the same, and change led state to ON or OFF present on Ci40 board.
| Object Name | Object ID | Resource Name | Resource ID |
|---|---|---|---|
| "Digital Input" | 3200 | "Counter" | 5501 |
Prior to running button-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.
Button-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:
$ button-led-controller: mkdir build $ button-led-controller/build: cd build $ button-led-controller/build: cmake ../docs $ button-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.
Button-Led Controller Application is getting started as a daemon. Although we could also start it from the command line as :
$ button_led_controller_appd
Output looks something similar to this :
