Data recording on specific channels about dwfpy HOT 4 CLOSED

How does the API decide which channel to record

AFAIK, you cannot specify the channels. You can only specify how many channels you want (as in Waveforms), and the channels are DIN0...DINn. So you either record all of them, or you need to rewire your setup.

I'd go with recording all the channels. If you'd have some sample code to help me get started, I'd highly appreciate it. I have only been able to get single channel data out of it (single dim ndarray when logic.record() is called). Thank you so much.

The returned vector is always one-dimensional. If you record 32 channels, it returns a c_uint32 vector, where the individual channels are encoded in the respective bits of the c_uint32.

Thank you, that worked perfectly!
