The following settings of lineMode set the line as a trigger line:
• digio.MODE_TRIGGER_IN: The line automatically responds to and detects externally generated
t
riggers. It detects falling-edge, rising-edge, or either-edge triggers as input. This line state uses
the edge setting specified by the trigger.digin[N].edge attribute.
• digio.MODE_TRIGGER_OUT: The line is automatically set high or low depending on the output
logic setting. Use the negative logic setting when you want to generate a falling edge trigger a
nd
us
e the positive logic setting when you want to generate a rising edge trigger.
• digio.MODE_TRIGGER_OPEN_DRAIN: Configures the line to be an open-drain signal. You can
us
e the line to detect input triggers or generate output triggers. This line state uses the edg
e
s
etting specified by the trigger.digin[N].edge attribute.
When the line is set as a synchronous acceptor, the line detects the falling-edge input triggers and
automatically latches and drives the trigger line low. Asserting an output trigger releases the latched
line.
When the line is set as a synchronous master, the line detects rising-edge triggers as input. For
output, the line asserts a TTL-low pulse.
Example
digio.line[1].mode = digio.MODE_TRIGGER_OUT
Set digital I/O line 1 to be an output trigger
line.
