Pattern generator sample buffer size

[AlanB]

I would like to use the digital pattern generator of an Analog Discovery 2 under control of a Python script.  It would appear that there is a 1024 sample buffer when used with PP outputs in custom mode.  Is there a way to extend this (such as by streaming data to the device from a PC, for example)?

Hi @AlanB

You could use the 4th device configuration with 16Ki digital-io/out sample buffer.
FDwfDeviceConfigOpen(#, 3, &hdwf)

There is no digital play mode with AD2 but only with Digital Discovery.

That may not be sufficient for my eventual needs, but it's more than I've got at the moment.  Thanks for your help.
