I’m reading the documentation about triggers and it seems that only physical signals on GPIO pins work as triggers. I wonder if it is possible to use a software variable as trigger. E.g. I have a serial to USB adapter that I can control using pyserial, why can’t I trigger the Chipwhisperer Lite capture when I receive/sent some specific bytes on the device via the USB to serial adapter? The delay should be not too high to invalid the measurement.
