Analog Discovery 2 - power supply SDK API

[Pseudonym1]

I'm trying to setup the Analog Discovery 2 as an automated variable power supply for a project. I'd like to control it using the SDK rather than the GUI. Is this supported, and if so what are the functions/API for the supplies?

The power supplies can be controlled under the *AnalogIO* functions (search for "supplies", not "supply"). If you're using the linux command line interface, they are the first 2 channels in the AnalogIO group.

Hi @Pseudonym1

You can find examples in the SDK folder: C:\Program Files (x86)\Digilent\WaveFormsSDK\ 

like: samples/py/AnalogIO_AnalogDiscovery2_Power.py

# set up analog IO channel nodes
# enable positive supply
dwf.FDwfAnalogIOChannelNodeSet(hdwf, c_int(0), c_int(0), c_double(True)) 
# set voltage to 5 V
dwf.FDwfAnalogIOChannelNodeSet(hdwf, c_int(0), c_int(1), c_double(5.0)) 
# enable negative supply
dwf.FDwfAnalogIOChannelNodeSet(hdwf, c_int(1), c_int(0), c_double(True)) 
# set voltage to -5 V
dwf.FDwfAnalogIOChannelNodeSet(hdwf, c_int(1), c_int(1), c_double(-5.0)) 
# master enable
dwf.FDwfAnalogIOEnableSet(hdwf, c_int(True))
