Analog Discovery Pro FDwfAnalogIOChannelNodeStatus returns unexpected values

[Icarus]

How should I query the Power supply voltage and current for the analog Discovery Pro?

Using the AnalogIO_AnalogDiscovery2_Power.py example and an voltage setting of 3.3V,  I get the following response for functions FDwfAnalogIOChannelNodeStatus 

USB: 58.537V    0.991A
AUX: 66.935V    1.027A

This was unexpected since I measured 3.3V at the VIO output on the header.

Using the analogIOChanhannelNodeSet and Configure functions I  stepped the voltages down to 1.0V in .5V increments succesfully, however the  FDwfAnalogIOChannelNodeStatus responses remained constant (same as above).

Hi @Icarus

Are you referring to the ADP3X50 or ADP5250 ?
The AnalogIO_AnalogDiscovery2_Power.py is for Analog Discovery 2.

See the manual in the WF SDK folder and the AnalogIO_ADP5250_Power.py example for ADP5250

Got it.  And thank you for the detailed response!   I have the ADP3450 and from the SDK snippets you attached, it appears that I don't actually have access to the current draw on the VIO header pin.
