On two different BBB's (latest revision) I've noticed strange behavior of AIN4. I have a TMP36 (analog temperature sensor) running on 3V3. Vout measures 712 mV ((712 - 500) / 10 C = 21 degree C). If I attach Vout to any AIN* except AIN4, I can use the BB and read out 712. So the ADC is working, as is the TMP36 sensor.
As soon as I connect Vout to AIN4, the voltage drops from 712 to 673 mV and slowly decreasing. Why is this? Is another part of the BBB already using AIN4 and is it reserved? No other capes or anything else connected to P8/P9. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
