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.
