power-saving mode in analog discovery 2

[cyberjjk]

hello. there appears to be a bug in the analog discovery 2....hardware or driver. in the original discovery...closing the device would reduce current drain from 400 mA to about 100 mA. however...the same command has no effect on analog discovery 2....current drain stays at ~400 mA. and led stays on...while on original discovery led goes off in the power saving mode. has this useful feature been disabled in discovery 2?

the commands we have tried which have no effect on discovery 2 are:

FDwfDeviceCloseAll();

and also tried

FDwfDeviceClose(hdwf);

nothing worked. on discovery 2.

Hi @cyberjjk,

I moved your thread to a section where more experience Analog Discovery 2/ Waveforms engineers look.

cheers,

Hi @cyberjjk

The WaveForms beta v3.8.17 adds option for this.
https://forum.digilentinc.com/topic/8908-waveforms-beta-download/

dwf.FDwfParamSet(DwfParamOnClose, c_int(0)) # 0 = run, 1 = stop, 2 = shutdown
dwf.FDwfDeviceOpen(c_int(-1), byref(hdwf))
...
dwf.FDwfDeviceClose(hdwf)

thank you. when will the beta version be released?

Hi @cyberjjk,

The beta version is available now in the link attila provided, though I don't know when this feature will be integrated into a formal release of WaveForms, but it's my understanding that all of our beta releases are very stable as is.

Thanks,
JColvin
