GPIO

Modules

Enabling and configuring GPIO pins
Configuring interrupts from GPIO pins

Macros

GPIO_LOCK_UNLOCK_CODE

#define GPIO_LOCK_UNLOCK_CODE   0x4C4F434B

Attention
An important aspect to consider is that tm4clib uses the AHB aperture for accessing the GPIO registers on the TM4C. The AHB must be explicitly enabled with a call to gpio_enable_ahb_aperture() before accessing any GPIO functionality.

Please see the individual GPIO modules for more details. To use the GPIO, the gpio.h header needs to be included:

#include <gpio.h>
