AM335x ICS 4.03 and ambient light sensor

Gunter Schmer

Hi all,

 

looking at the AM335x ICS release notes we are supporting the AM335x EVM Ambient Light sensor via I2C interface driver in Android

http://processors.wiki.ti.com/index.php/TI-Android-ICS-4.0.3-DevKit-3.0.1_ReleaseNotes

For cost reasons a customer is looking at other ambient light sensors without I2C interface, and is intending to use the AM335x ADC to monitor voltage level of the light sensor, instead of reading through I2C. Is there a similar driver in Android for ADC that could be used as a good starting point?

 

Thanks,

--Gunter

    Hi Gunter,

    Android does not hold any strict guide line of sensor h/w. One can use any light sensor, but the condition is that inside linux system - sensor driver should report event to input subsystem ( i.e. sensor should be register as input driver).

    I hope this will give you option to choose over other sensor.
