SDK FDwfDigitalOutInternalClockInfo returning frequency of 0.0

[joe.a]

Hey all,

I'm working with the waveforms SDK in python and attempting to use the digital out functionality for generating a logic pulse. 

Unfortunately, I'm running into issues when calculating the divider setting. I've followed this back, and it appears to originate from FDwfDigitalOutInternalClockInfo returning a frequency of 0.0.

I'm working with an Analog Discovery 2, and I know from previous messing around that 100000000.0 is typically returned. I'm assuming that I'm setting this up incorrectly in some way. Is there a known situation/setup where the AD2 will return 0.0 ?

Additionally, FDwfDigitalOutCounterInfo is also returning a counter of 0. I assume this is related to the internal clock frequency as well.

Any help is greatly appreciated :)

Hi @joe.a

The FDwfDigitalOutInternalClockInfo for AD2 should return 100e6. This device has no frequency adjustment feature, so this is fixed/hardcoded.
The FDwfDigitalOutCounterInfo returns 0 because it is not supported by AD2, only by newer devices like AD3, ADP3X50, ADP2230, Digital Discovery
