Max Samples using Logic Analyzer with Python

[ToddW]

I am writing python code and trying to get the max number of samples from the logic analyzer with a Discovery2.  I set the value to 16384, but I only get 4096 valid samples followed by all 0's.  I set the number of samples with dwf.FDwfDigitalInBufferSizeSet(self.device_handle, c_int(buffer_size)) I also use the record function from github.  How do I get all 16384 samples with valid data?

Hi @ToddW,

You will want to change the configuration from the default option (which only has buffer for 4096 samples) a different configuration that does allocate the 16 Ki buffer with dwf.FDwfDeviceConfigOpen

There is a little more information about this on this thread here:

Let me know if you have any questions.

Thanks,

That worked.  It took a bit to figure out that dwf.FDwfDeviceConfigOpen replaced dwf.FDwfDeviceOpen to open the device originally.  Thanks.
