  1.    attila reacted to an answer to a question: Analog Discovery Pro FDwfAnalogIOChannelNodeStatus returns unexpected values

    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.

    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).

    Got it. Thank you for the info. And thank you for responding so quickly!

    In the example code DigitalDiscovery_RecordToFile16.py, the acquisition mode is set to Record with dwf.FDwfDigitalInAcquisitionModeSet(hdwf, acqmodeRecord) [ line 84 in my attached version]. However, function "dwf.FDwfDigitalInAcquisitionModeInfo(hdwf) ", returns c_int(3), which I thought from the SDK manual meant only acqmodeSingle and acqmodeScanShift were valid (see attached SDK exerpt) Am I miss understanding something in the Manual?
