Macro Definition Documentation

◆ BTN0_INT_FLANK

#define BTN0_INT_FLANK GPIO_FALLING

Default interrupt flank definition for the button GPIO.

Definition at line 49 of file board.h.

◆ BTN0_MODE

#define BTN0_MODE GPIO_IN_PU

Default button GPIO mode definition.

Definition at line 43 of file board.h.

◆ BTN0_PIN

#define BTN0_PIN GPIO0

Default button GPIO pin definition.

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

Definition at line 38 of file board.h.

◆ BUTTON0_PIN

#define BUTTON0_PIN BTN0_PIN

Definition for compatibility with previous versions.

Definition at line 55 of file board.h.

◆ LED0_ACTIVE

#define LED0_ACTIVE 1

LED is high active.

Definition at line 65 of file board.h.

◆ LED0_PIN

#define LED0_PIN GPIO15

LED is connected to GPIO15.
