Wandboard Quad - Yocto ADC and I2C support

Hi everyone,

 

It's too bad that the Wandboard has no readily available analog inputs. I'm a bit stuck -- was hoping for a quick solution for temperature, humidity and lux measurement.

 

Since there are no analog inputs, I thought of using the ADS1015 or ADS1115 for i2c-based measurement so that I will get 4 channels.

 

I'm using the Yocto to build the image. Was wondering if the ADS1x15 driver is available? Is it straightforward to use i2c bus on the Wandboard?

 

Any pointers?

 

Thanks.
