Macro Definition Documentation

◆ BACKLIGHT_OFF

#define BACKLIGHT_OFF gpio_clear(BACKLIGHT_PIN)

Turn backlight off.

Definition at line 114 of file board.h.

◆ BACKLIGHT_ON

#define BACKLIGHT_ON gpio_set(BACKLIGHT_PIN)

Turn backlight on.

Definition at line 113 of file board.h.

◆ BACKLIGHT_PIN

#define BACKLIGHT_PIN GPIO33

Backlight pin.

Definition at line 112 of file board.h.

◆ BTN0_INT_FLANK

#define BTN0_INT_FLANK GPIO_FALLING

Default interrupt flank definition for the button GPIO.

Definition at line 58 of file board.h.

◆ BTN0_MODE

#define BTN0_MODE GPIO_IN_PU

Default button GPIO mode definition.

Since the GPIO of the button is pulled up with an external resistor, the mode for the GPIO pin has to be GPIO_IN.

Definition at line 52 of file board.h.

◆ BTN0_PIN

#define BTN0_PIN GPIO0

Default button GPIO pin definition.

LILYGO TTGO T8 ESP32-S2 boards have a BOOT button connected to GPIO0, which can be used as button during normal operation. Since the GPIO9 pin is pulled up, the button signal is inverted, i.e., pressing the button will give a low signal.

Definition at line 44 of file board.h.

◆ BUTTON0_PIN

#define BUTTON0_PIN BTN0_PIN

Definition for compatibility with previous versions.

Definition at line 64 of file board.h.

◆ SDCARD_SPI_PARAM_CLK

#define SDCARD_SPI_PARAM_CLK SPI1_SCK

Definition at line 77 of file board.h.

◆ SDCARD_SPI_PARAM_CS

#define SDCARD_SPI_PARAM_CS SPI1_CS0

Definition at line 76 of file board.h.

◆ SDCARD_SPI_PARAM_MISO

#define SDCARD_SPI_PARAM_MISO SPI1_MISO

Definition at line 79 of file board.h.

◆ SDCARD_SPI_PARAM_MOSI

#define SDCARD_SPI_PARAM_MOSI SPI1_MOSI

Definition at line 78 of file board.h.

◆ SDCARD_SPI_PARAM_POWER

#define SDCARD_SPI_PARAM_POWER GPIO_UNDEF

Definition at line 80 of file board.h.

◆ SDCARD_SPI_PARAM_SPI

#define SDCARD_SPI_PARAM_SPI SPI_DEV(1)

Definition at line 75 of file board.h.
