ads1115 readings

[gary s]

Just starting to play with webiopi. Simple LED controls work fine, but when I hook up an ADS1115 I2C ADC board things get a little funny.

Running basic config file with the following added for ads1115 support.

ads0 = ADS1115

I can see module at port 48 with i2cdetect.

The ads1115 has vcc(3v), gnd, sda, sdc connected to the PI. A0,A1 and A2 are connected to ground and A3 is connected to 3.3v for testing

When I run the device monitor I see the device but the channels  dont seem to keep a stable value.

I would think A0-A2 would be 0v (or very close) and A3 would be 3v, but  all 4 inputs seems to float from 3.3v to 0 volts as the device is being polled.

Should this device be more stable?  did I miss something?

I'm having the same problem. I'm using the device within Cayenne and Weaved with webiopi. 

I think the device has been setup with a default 'one-shot' state. I'm trying to find the file with those default values.
