Command Description
io-read <portID>
Reads the state of the GPIO pin identified by the
<portID>
.
The <portID> is a combination of the port name (g or f)
and the bit to read (0 through 7), for instance g0 would
read the first pin on port g.
The command requires the <portID> be set to input.
io-write <portID> <state>
Writes the value of <state> to the GPIO pin identified by
the <portID>.
The <portID> is a combination of the port name (g or f)
and the bit to read (0 through 7), for instance g0 would
read the first pin on port g.
The <state> can equal 1 or 0.
The command requires the <portID> be set to output.
