Howdy Mathias,

 

OMAP has 3 distinct i2c controllers, which line have you got your pressure sensor hooked up to? I believe the MADC is on i2c-1.

Subject: [Gumstix-users] Cannot get ADC and I2C together

 

Hi

I am using an I2C pressure sensor that works fine alone. I also have an analog ambient light sensor, that I was using at ADCIN4.

The problem is that when I put them together I can't read the I2C sensor anymore, that is, the reading is not updated.

 

I think that this has something to do to the fact that the TWL4030 is accessed via I2C but I don't know where is the problem.

 

 

Thanks,

Mathias
