Macro Definition Documentation

BTN0_MODE

#define BTN0_MODE   GPIO_IN

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 39 of file board.h.

BTN1_MODE

#define BTN1_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 59 of file board.h.

BTN2_PIN

#define BTN2_PIN   GPIO9

BOOT button GPIO pin definition.

The HiP-Badge 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.
