MCC USB-1808x trigger

[darksied_9]

I am using MCC 1808x for data acquisition and have multiple sensors integrated to it, using the Ain Scan method I am storing the data, but I don't want to continuously monitor the data. I was looking at the trigger mode can I set the trigger with the sensor that I am using so that once that sensor is triggered data acquisition will start and once there is no trigger it will continuously monitor the status, or I have to use an external trigger.  

What is this line in a_in_scan_with_trigger.py ai_device.set_trigger(trigger_types[trigger_type_index], 0, 0, 0, 0) do?

We have a few products that can perform analog triggering, but the USB-1808X is not one of them. The set_trigger function you mentioned has extra parameters for analog level and hysteresis. These parameters are ignored when using the USB-1808X because it has only TTL trigger (ITRIG pin) capabilities. Details about set_trigger can be found here.
