Detailed Description

Board definitions for ESP32-S2-DevKit boards.

The board definitions in this file are valid for Espressif ESP32-S2-DevKitx boards that use one of the following modules:

ESP32-S2-MINI-1x module (ESP32-S2-DevKitM-1 board)
ESP32-S2-WROOM-1x module (ESP32-S2-DevKitC-1 board)
ESP32-S2-WROOM-2x module (ESP32-S2-DevKitC-1 board)

where x stands for the module version with and without U (external antenna connector).

Any modifications required for specific applications can be overridden by application-specific board configuration.

Button pin definitions
#define	BTN0_PIN GPIO0
	Default button GPIO pin definition.

#define	BTN0_MODE GPIO_IN_PU
	Default button GPIO mode definition.

#define	BTN0_INT_FLANK GPIO_FALLING
	Default interrupt flank definition for the button GPIO.

#define	BUTTON0_PIN BTN0_PIN
	Definition for compatibility with previous versions.

LED (on-board) configuration
ESP32-S2-DevKit boards have a SK68XXMINI-HS smart RGB-LED connected to GPIO18 on-board. The WS281x driver module `ws281x` can be used to control it. Note GPIO18 is also be defined as DAC channel. The RGB-LED can be used as long as GPIO18 is not initialized as DAC channel with the function `dac_init`.
#define	WS281X_PARAM_PIN (GPIO18)
	GPIO pin connected to the data pin.

#define	WS281X_PARAM_NUMOF (1U)
	Number of LEDs chained.

Macro Definition Documentation

◆ BTN0_INT_FLANK

#define BTN0_INT_FLANK GPIO_FALLING

Default interrupt flank definition for the button GPIO.

Definition at line 64 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 58 of file board.h.

◆ BTN0_PIN

#define BTN0_PIN GPIO0

Default button GPIO pin definition.

ESP32-S2-DevKit boards have a BOOT button connected to GPIO9, 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 50 of file board.h.

◆ BUTTON0_PIN

#define BUTTON0_PIN BTN0_PIN

Definition for compatibility with previous versions.

Definition at line 70 of file board.h.

◆ WS281X_PARAM_NUMOF

#define WS281X_PARAM_NUMOF (1U)

Number of LEDs chained.

Definition at line 89 of file board.h.

◆ WS281X_PARAM_PIN

#define WS281X_PARAM_PIN (GPIO18)

GPIO pin connected to the data pin.

Definition at line 86 of file board.h.
