digital pattern generator with external trigger

[user2051]

Hi,

             I'm new to the digital discovery and Waveforms. I am trying to figure out how to setup an external trigger with the digital pattern generator and the only trigger configurations available in the "Patterns" window are none, logic, logic detector, and manual. It isn't clear to me how to specify which pin the digital discovery should expect to see my external trigger. My research of all the documentation on the digital discovery and Waveforms has lead me astray. The Logic Analyzer window offers more configuration options but it isn't clear to me that these options carry over to the pattern generation utility. Can someone tell me how to configure the digital pattern generator for external triggering?

Hi @user2051

The Digital-Out (Patterns) can be trigger by a digital line, through the Digital-In (Logic Analyzer) trigger detector like this:

dwf.FDwfDigitalInTriggerSet(hdwf, c_int(0), c_int(0), c_int(1<<7), c_int(0)) # DIN7 rising edge
dwf.FDwfDigitalOutTriggerSourceSet(hdwf, c_ubyte(3)) # trigsrcDetectorDigitalIn
