Hi Sir,

I am using iMX8M Mini EVK and Android 9 AOSP Framework.
I am successfully able to build the AOSP for my board and its running fine. 

 

Now i want to connect DHT 11 sensor to this board at GPIO and want to read it's value.

for that i enabled IIO and DHT11 in iMX8 AOSP kernel menuconfig and build it.

 

And As per my understanding there is test app is available in AOSP /hardware/libhardware/tests/nusensors folder.

Now I want to use this test App to check my sensor value via Sensor HAL.

but I am not sure how to do that.

 

Please suggest me how can i use this test app to raed my sensor value using sensor HAL.

 

Thanks & Regards,

Maneesh Singh
