Command Description
SET GPIO DATA <bit-mask> Sets all the data out control bits.
<bit-mask> is an 8 bit mask expressed as 2 hex digits.
This value should be in the range 00-FF. The mask is
encoded as follows:
7 6 5 4 3 2 1 0
GPIO8 GPIO7 GPIO6 GPIO5 GPIO4 GPIO3 GPIO2 GPIO1
Each GPIO output bit is set to the corresponding value in
the mask. If a GPIO signal is set as an input, the value is
set but has no effect. If a GPIO signal is set for a special
function, the bit value give is ignored. For example, a
hex value of 80 sets GPIO8 to a 1 (high), all other GPIO
signals to low, except those set as special functions.
NOTE: The default output bit value on power up or reset
is 0 for all GPIO signals.
SHOW GPIO DATA Shows the current state of the GPIO signals.
Example:
Local> set gpio data 80
Local> show gpio data
