set_digital_analog_trigger_operand(operand)

This function is define in the header file, but it is not in the manual.

set_trigger_digital_port_properties(directions)

This function will set the individual Digital channels trigger directions. Each trigger direction consists of a channel name and a direction. If the channel is not included in the array of PS2000ADigitalChannelDirections the driver assumes the digital channel’s trigger direction is PS2000A_DIGITAL_DONT_CARE.
