Detailed Description

Board specific definitions for TTGO T-Beam board.

TTGO T-Beam is an ESP32 development board with 8 MB Flash that uses the EPS32 chip directly. It integrates a SemTech SX1276 or SX1278 for LoRaWAN communication in the 433 MHz or the 868/915 MHz band, respectively. Additionally, it has an OLED display connected via I2C on board.

For detailed information about the configuration of ESP32 boards, see section Common Peripherals.

Note: Most definitions can be overridden by an application-specific board configuration.

Macro Definition Documentation

◆ BTN0_INT_FLANK

#define BTN0_INT_FLANK GPIO_FALLING

Default interrupt flank definition for the button GPIO.

Definition at line 67 of file board.h.

◆ BTN0_MODE

#define BTN0_MODE GPIO_IN

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 55 of file board.h.

◆ BTN0_PIN

#define BTN0_PIN GPIO39

Default button GPIO pin definition.

Definition at line 46 of file board.h.

◆ BUTTON0_PIN

#define BUTTON0_PIN BTN0_PIN

Definition for compatibility with previous versions.

Definition at line 60 of file board.h.
