Yes
Usage
digio.writeport(
data
)
data
The value to write to the port (0 to 63)
Details
The binary representation of the value indicates the output pattern to be written to the I/O port. For example, a
value of 63 has a binary equivalent of 111111 (all lines are set high); a
data
value of 42 has a binary equivalent
of 101010 (lines 2, 4, and 6 are set high, and the other 3 lines are set low).
An instrument reset does not affect the present states of the digital I/O lines.
Example
digio.writeport(63)
Sets digital I/O lines 1 through 6 high (binary
111111).
