Managing the I/O Interface

To manage the I/O interfaces such as digital and analog I/Os, LEDs, push button,
and hardware settings driven by GPIO, you can use AT commands, Linux shell
commands, or the Legato Application Framework.
• AT Commands
See AT!FWD?GPIO and AT!FWD=GPIO documentation on
mapping in Table 3-10
As some FX30S GPIOs are driven by an I/O expander, do not use standard
AT+WIOR/WIOW AT commands for the FX30S.
Warning:
Most FX30S GPIOs are preconfigured. Do not use the AT+WIOCFG
command! Using this command could make the FX30S inoperable.
Here are some AT command examples for GPIOs:

To...
Turn on the green User LED
Turn off the green User LED
Read the push button state
Read the analog input value (in mV)
