Waits up to three seconds for a trigger to be detected on trigger line 4, then displays if
the trigger was detected:
triggered = digio.trigger[4].wait(3)
print(triggered)
Output: false (no triggers detected) true (trigger detected)
Sets a digital I/O line high or low.
digio.writebit(bit, data)
bit: Digital I/O line number (1 to 14)
data: Value to write to the bit; 0 (low) or 1 (high)

If the output line is write protected, via the
attribute, the command will be ignored.

The reset function does not affect the present states of the digital I/O lines.
digio.readbit (on page 9-48),

Sets digital I/O line 4 low (0):
digio.writebit(4, 0)
Writes to all digital I/O lines.
digio.writeport(data)
data: Value to write to the port; 0 to 16383.

The binary representation of data indicates the output pattern to be written to the
I/O port. For example, a data value of 170 has a binary equivalent of
00000010101010. Lines 2, 4, 6 and 8 are set high (1), and the other 10 lines are
set low (0).

Write protected lines will not be changed (see
