Peripheral firmware overview

67/229

When debug mode is used, GPIO pointer is initialized in 71x_lib.c file:

#ifdef _GPIO0

GPIO0 = (GPIO_TypeDef *)GPIO0_BASE;

#endif

#ifdef _GPIO1

GPIO1 = (GPIO_TypeDef *)GPIO1_BASE;

#endif

#ifdef _GPIO2

GPIO2 = (GPIO_TypeDef *)GPIO2_BASE;

#endif

In debug mode the following variables are defined in 71x_conf.h file:

●

_GPIO is defined to include the GPIO library

●

_GPIO0, _GPIO1 and _GPIO2 are defined to access the peripheral registers.

#define TQFP144

#define _GPIO

#define _GPIO0

#define _GPIO1

#ifdef TQFP144

#define _GPIO2

#endif /*TQFP144*/

GPIO pin mode enumeration

The following enumeration defines the different possible pin modes for GPIO peripheral.

GpioPinMode_TypeDef enumeration is defined in 71x_gpio.h file:

typedef enum

{

GPIO_HI_AIN_TRI,

GPIO_IN_TRI_TTL,

GPIO_IN_TRI_CMOS,

GPIO_IPUPD_WP,

GPIO_OUT_OD,

GPIO_OUT_PP,

GPIO_AF_OD,

GPIO_AF_PP

} GpioPinMode_TypeDef;

Table 30 describes the pin modes.
