Can the AD3 be power-cycled or restarted over USB?

[idegani]

After running for several hours, I see glitches in the sine wave that is generated by the AD3's waveform W1/W2 pins. Unplugging and re-plugging the device fixes it.

Is there a way to perform a hard-reset on the device over USB? Ideally I could send the restart command over libdwf, wait for a few seconds and then reconnect. I looked at DwfDeviceReset(HDWF hdwf) but that just resets parameters...

I can also try to gather more info for debug purposes if there is interest, just let me know how to collect/query it. Thanks!

Hi @idegani

Could you add some screenshots? What is the device temperature when this happens?

Adjusting the device frequency, phase or the clock mode should reconfigure the device clocking ICs
FDwfDeviceParamSet(hdwf, DwfParamFrequency, 90000000) 90MHz
FDwfDeviceParamSet(hdwf, DwfParamFrequency, 100000000) 100MHz

To reconfigure most of the device ICs on open, make sure the on-close global option is 0 (shutdown)
FDwfParamSet(DwfParamOnClose, 0)
FDwfDeviceClose...
FDwfDeviceOpen...

Thanks for the speedy response! I will try these commands
The device does feel warm when the issue arises.

I'll record the exact temperature next time I see the issue and will post a screenshot / pic of what I'm seeing.

Thanks again!
