How to acquire 2 Channel Analog signals with digital trigger.

[kang]

He llo. I'm trying to acquire Analog signal with digital trigger by using python programming.

 

This code makes one analog signal and one digital signal on DIO pin 0. And i succeeded acquiring analog signal data by using digital trigger signal. For this process, i connected with DIO pin 0 and channel 2+. But i should acquire 2 channel Analog signals. For that, I have to disconnect DIO pin 0 and Channel 2+. I searched the DigitalIn_Trigger.py file, but I don't know What i have to do. Please help me and Thank you very much for reading.

Hi @kang

Simply use one of the trigger IOs.
dwf.FDwfAnalogInTriggerSourceSet(hdwf, trigsrcExternal1)

and if you want to specify the edge: rising, falling or either:
dwf.FDwfAnalogInTriggerConditionSet(hdwf, DwfTriggerSlopeFall)
