Evaluating addition of a custom sensor to zephyr sensor model

[Ubaid_M]

Hi,

With zephyr's example : https://github.com/zephyrproject-rtos/example-application

I am evaluating to add a sample clap sensor as a custom sensor into the zephyr sensor driver model.

But doing everything right, The build system is not recognizing the custom sensor files and generating undefined APIs errors.

I am attaching my project : Zephyr_RTOS_Proficiency.zip

I was able to add the CONFIG symbol, the binding for KY-038 sensor and it is working fine when I call it from prj.conf.

But I am unable to call the APIs i defined into main.c

My custom sensor is defined at : Zephyr_RTOS_Proficiency\drivers\sensor\GPIO_Sensor_KY_038

Kindly suggest

Hello, 

Are you using the nRF Connect SDK as base or the Zephyr SDK?

Kind regards,

Hello Øyvind

I am using nrf Connect SDK v2.6.0 and nrf52840dk for evaluation

Building on vscode nrf connect extension

Are you able to share more details on your project and what exactly fails? I was not able to build the project on my side. 

Perhaps the nRF Connect SDK Intermediate course in our Developer Academy is something to look at in regards to driver development.

I am unable to include the defined APIs in main.c

Seems something to do with CMAKE & KConfig, cannot figure out what
