Security
Level
2 (data)
Device Type All
Default N/A
Description Writes the included value to the indicated GPIO port and bit. This command is applied dynamically and
does not require a restart.
The command requires a parameter that identifies the GPIO port and bit to be write to and the state to
which it is to be set, for example:
io-write f1 1 : Writes the value 1 to the f port first bit.
io-write g7 0 : Writes the value 0 to the g port seventh bit.
The written value, zero (0) or one (1), will be converted to an output voltage on the indicated port and
pin. Please refer to the Airborne DP500 Family data book for the GPIO electrical specification.
Port assignment and exceptions:
f0 Read (POST output) g0 Read or Write
f1 Read or Write g1 Read or Write
f2 Read (RF_LINK output) g2 Read or Write
f3 Read (WLN_CFG output) g3 N/A
f4 Read or Write g4 N/A
f5 Read or Write g5 N/A
f6 Read (LED_CON output) g6 Read or Write
f7 Read or Write g7 Read or Write
When the LED signal has not been disabled those bits indicated as LED Outputs can only be read. To
disable the LED‟s use one of the following commands post-led, rf-link-led, wln-cfg-led and
conn-led
.
The ports indicated as N/A cannot be written to. Any attempt to set an unavailable port will be ignored.
