Command Description
io-pullup <portID> <state>
Enables or disables the internal pull-up resistors for the
specified GPIO pin.
This command is temporary and is not persistent across a
restart or power cycle. To set the default direction of the
ports the io-pullup-f or io-pullup-g commands
must be used.
The command has the same bit restrictions the io-
pullup-f
and io-pullup-g command have.
The internal pull-up resistor is enabled by default.
The <portID> is a combination of the port name (g or f)
and the bit to apply the state to (0 through 7), for instance
g0
would affect the first pin on port g.
The <state> can be set as either enable or disable.
io-dir-f <state>
Sets the direction of the GPIO pins in port f. It is required
to issue a commit after the command for the parameters
to be persistent across restarts or power cycles.
This command requires a restart or power cycle to be
applied.
For a pin to be an input it must be set to 1, for output it
must be set to 0.
The <state> for the pins is the decimal value of the 8 bit
binary value that represents the desired state of the 8
GPIO in the port, e.g. 11111111 = 255 (all pins input),
11110000
= 240 (7,6,5,4 = Input, 3,2,1,0 = output).
Requires that the primary UART and LED signals have been
disabled.
io-dir-g <state>
Sets the direction of the GPIO pins in port g. It is required
to issue a commit after the command for the parameters
to be persistent across restarts or power cycles.
This command requires a restart or power cycle to be
applied.
For a pin to be an input it must be set to 1, for output it
must be set to 0. Note that pin 3,4 and 5 are ignored
The <state> for the pins is the decimal value of the 8 bit
binary value that represents the desired state of the 8
GPIO in the port, e.g. 11111111 = 255 (all pins input),
11110000
= 240 (7, 6= Input; 2, 1, 0 = output; 5, 4, 3 =
ignored).
Requires that the secondary UART has been disabled.
