Details
Usage
digio.line[ N ].state = state
state = digio.line[ N ].state
N
Digital I/O trigger line (1 to 6)
state
Set the line low:
digio.STATE_LOW
or
0
Set the line high:
digio.STATE_HIGH
or
1
Details
When a reset occurs, the digital line state can be read as high because the digital line is reset to a
digital input. A digital input floats high if nothing is connected to the digital line.
This returns the integer equivalent values of the binary states on all six digital I/O lines.
Set the state to
digio.STATE_LOW
to clear the bit; set the state to
digio.STATE_HIGH
to set the
bit.
Example
digio.line[1].mode = digio.MODE_DIGITAL_OUT
digio.line[1].state = digio.STATE_HIGH
Sets line 1 (bit B1) of the digital I/O port high.
