How to use the nifgen.OutputMode function in nifgen

def example(resource_name, options, shape, channel):
    with nifgen.Session(resource_name=resource_name, options=options, channel_name=channel) as session:
        # CONFIGURATION
        # 1 - Set the mode to Script
        session.output_mode = nifgen.OutputMode.SCRIPT

        # 2 - Configure Trigger:
        # SOFTWARE TRIGGER: used in the script
        session.script_triggers[0].script_trigger_type = nifgen.ScriptTriggerType.SOFTWARE_EDGE  # TRIG_NONE / DIGITAL_EDGE / DIGITAL_LEVEL / SOFTWARE_EDGE
        session.script_triggers[0].digital_edge_script_trigger_edge = nifgen.ScriptTriggerDigitalEdgeEdge.RISING  # RISING / FAILING

        # 3 - Calculate and write different waveform data to the device's onboard memory
        session.channels[channel].write_waveform('sine', calculate_sinewave())        # (waveform_name, data)
        session.channels[channel].write_waveform('rampup', calculate_rampup())
        session.channels[channel].write_waveform('rampdown', calculate_rampdown())
        session.channels[channel].write_waveform('square', calculate_square())
        session.channels[channel].write_waveform('triangle', calculate_triangle())
        session.channels[channel].write_waveform('noise', calculate_gaussian_noise())

        # 4 - Script to generate
        # supported shapes: SINE / SQUARE / TRIANGLE / RAMPUP / RAMPDOWN / NOISE / MULTI
