Button pin definitions
#define	BTN0_PIN GPIO9
	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
LED configuration depends on Wemos ESP32-C3 mini board version: v1.0.0 has one LED connected to GPIO7. v2.1.0 has one 24-bit RGB-LED WS2812B connected to GPIO7.
#define	WS281X_PARAM_PIN (GPIO7)
	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 50 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 44 of file board.h.

◆ BTN0_PIN

#define BTN0_PIN GPIO9

Default button GPIO pin definition.

The Wemos ESP32-C3 mini board has 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 36 of file board.h.

◆ BUTTON0_PIN

#define BUTTON0_PIN BTN0_PIN

Definition for compatibility with previous versions.

Definition at line 56 of file board.h.

◆ WS281X_PARAM_NUMOF

#define WS281X_PARAM_NUMOF (1U)

Number of LEDs chained.

Definition at line 80 of file board.h.

◆ WS281X_PARAM_PIN

#define WS281X_PARAM_PIN (GPIO7)

GPIO pin connected to the data pin.

Definition at line 77 of file board.h.
