7.4 General Purpose Input/Output (GPIO)

The Fastrack M1306B provides two General Purpose Input / Output lines available for

external use: GPIO4 and GPIO5.

These GPIOs may be controlled by AT commands:

•

AT+WIOW for a write access to the GPIO value, when the GPIO is used as an

output,

•

AT+WIOR for a read access to the GPIO value, when the GPIO is used as an

input.

Refer to "AT Commands Interface Guide" [7] for further information on AT commands.

After reset, both GPIOs are configured as inputs. The

AT+WIOM command has to be

used to change this configuration (refer to "AT Commands Interface Guide" [7] for

further details).
