This function resets digital I/O line values to their factory defaults.
Type TSP-Link accessible Affected by Where saved Default value
Function Yes
Usage
digio.line[ N ].reset()
N
The digital I/O line (1 to 6)
Details
This function resets the following attributes to their default values:
•
digio.line[ N ].mode
•
trigger.digin[ N ].edge
•
trigger.digout[ N ].logic
•
trigger.digout[ N ].pulsewidth
•
trigger.digout[ N ].stimulus
It also clears
trigger.digin[ N ].overrun
.
Example
-- Set the digital I/O trigger line 3 for a falling edge
digio.line[3].mode = digio.MODE_TRIGGER_OUT
trigger.digout[3].logic = trigger.LOGIC_NEGATIVE
-- Set the digital I/O trigger line 3 to have a pulsewidth of 50 microseconds.
trigger.digout[3].pulsewidth = 50e-6
-- Use digital I/O line 5 to trigger the event on line 3.
trigger.digout[3].stimulus = trigger.EVENT_DIGIO5
-- Print configuration (before reset).
print(digio.line[3].mode, trigger.digout[3].pulsewidth, trigger.digout[3].stimulus)
-- Reset the line back to factory default values.
digio.line[3].reset()
-- Print configuration (after reset).
print(digio.line[3].mode, trigger.digout[3].pulsewidth, trigger.digout[3].stimulus)
Output before reset:
digio.MODE_TRIGGER_OUT 5e-05 trigger.EVENT_DIGIO5
Output after reset:
digio.MODE_TRIGGER_IN 1e-05 trigger.EVENT_NONE
