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:
•
for a write access to the GPIO value, when the GPIO is used as an
AT+WIOW
output,
•
for a read access to the GPIO value, when the GPIO is used as an
AT+WIOR
input.
Refer to "AT Commands Interface Guide" [7] for further information on AT commands.
After reset, both GPIOs are configured as inputs. The
used to change this configuration (refer to "AT Commands Interface Guide" [7] for
further details).
