Macro Definition Documentation

◆ BOARD_BUTTON_ACTIVE_LOW

#define BOARD_BUTTON_ACTIVE_LOW true

Button GPIO polarity.

If a button press pulls the GPIO pin low, this setting is true. This is the case for many EFR32 boards, such as the Thunderboard Sense 2 and the BRD4001 Evaluation Board. Otherwise, if a button press pulls the GPIO pin high, this setting should be set to false.

Definition at line 151 of file board.h.

◆ BOARD_BUTTON_ID_LIST

#define BOARD_BUTTON_ID_LIST {BOARD_GPIO_ID_BUTTON0, BOARD_GPIO_ID_BUTTON1}

Button definitions.

If board contains buttons, The button IDs list is defined here. The button IDs are mapped to GPIO IDs. If not defined, a dummy button driver is compiled, so that applications can use the button driver unconditionally.

Note: in order for application to use buttons, see here.

Definition at line 141 of file board.h.

◆ BOARD_BUTTON_INTERNAL_PULL

#define BOARD_BUTTON_INTERNAL_PULL true

Button GPIO internal pull up/down.

Some buttons don't have any pull-up or pull-down resistor installed on the board. They need it to be setup in software. Set BOARD_BUTTON_INTERNAL_PULL to true to enable internal pull-up(down). Pull-up(down) is enabled when BOARD_BUTTON_ACTIVE_LOW is true(false).

◆ BOARD_GPIO_ID_BUTTON0

#define BOARD_GPIO_ID_BUTTON0 2

Definition at line 86 of file board.h.

◆ BOARD_GPIO_ID_BUTTON1

#define BOARD_GPIO_ID_BUTTON1 3

Definition at line 87 of file board.h.

◆ BOARD_GPIO_ID_LED0

#define BOARD_GPIO_ID_LED0 0

GPIO IDs.

User friendly name for GPIOs (IDs mapped to the BOARD_GPIO_PIN_LIST table)

Definition at line 84 of file board.h.

◆ BOARD_GPIO_ID_LED1

#define BOARD_GPIO_ID_LED1 1

Definition at line 85 of file board.h.

◆ BOARD_GPIO_ID_UART_IRQ

#define BOARD_GPIO_ID_UART_IRQ 5

Interrupt pin for dual mcu app, unread indication.

This only used in dualmcu_app application to announce with GPIO pin that there is incoming indication to be read from device.

It is optional definition.

Definition at line 108 of file board.h.

◆ BOARD_GPIO_ID_USART_WAKEUP

#define BOARD_GPIO_ID_USART_WAKEUP 4

pin for dual mcu app, usart wakeup

This only used in dualmcu_app application to wake up the usart driver when detecting a transition on the usart RX pin.

It is optional definition.

Definition at line 97 of file board.h.

◆ BOARD_GPIO_PIN_LIST

#define BOARD_GPIO_PIN_LIST

Value:

                                        {{GPIOF, 4}, /* PF04 */\
                                        {GPIOF, 5}, /* PF05 */\
                                        {GPIOF, 6}, /* PF06 */\
                                        {GPIOF, 7}, /* PF07 */\
                                        {GPIOA, 1}, /* PA01. required by the dual_mcu app. usart wakeup pin (= BOARD_USART_RX) */\
                                        {GPIOD, 8}} /* PD08. required by the dual_mcu app (indication signal) */

GPIO definitions.

If board needs GPIOs, they are defined here. If not defined, a dummy GPIO driver is compiled, so that applications can use the GPIO driver unconditionally.

For Silabs EFR32 family, the list contains GPIO port/pin number pairs.

Note: in order for application to use GPIOs, see here.

Definition at line 71 of file board.h.

◆ BOARD_LED_ACTIVE_LOW

#define BOARD_LED_ACTIVE_LOW false

LED GPIO polarity.

If LEDs turn on when the GPIO pin is driven low, this setting is true. Many EFR32 boards, such as the Thunderboard Sense 2 and the BRD4001 Evaluation Board have active high LEDs, so this setting should remain false.

Definition at line 129 of file board.h.

◆ BOARD_LED_PIN_LIST

#define BOARD_LED_PIN_LIST {BOARD_GPIO_ID_LED0, BOARD_GPIO_ID_LED1}

LED definitions.

If board contains LEDs, The LED IDs list is defined here. The LED IDs are mapped to GPIO IDs. If not defined, a dummy LED driver is compiled, so that applications can use the LED driver unconditionally.

Note: in order for application to use LEDs, see here.

Definition at line 120 of file board.h.

◆ BOARD_USART_ID

#define BOARD_USART_ID 0

USART ID.

Valid values: 0, 1, ... (to match BOARD_USART)

Note: in order for application to use USART, see here.

Definition at line 25 of file board.h.

◆ BOARD_USART_ROUTELOC_RXLOC

#define BOARD_USART_ROUTELOC_RXLOC USART_ROUTELOC0_RXLOC_LOC0

RX routeloc definition.

Valid values: USART_ROUTELOC0_RXLOC_LOC0, USART_ROUTELOC0_RXLOC_LOC1, ...

Definition at line 33 of file board.h.

◆ BOARD_USART_ROUTELOC_TXLOC

#define BOARD_USART_ROUTELOC_TXLOC USART_ROUTELOC0_TXLOC_LOC0

TX routeloc definition.

Valid values: USART_ROUTELOC0_TXLOC_LOC0, USART_ROUTELOC0_TXLOC_LOC1, ...
