Detailed Description

Custom button_t structure.

This structure allows the user to select its gpio pin, and set for pullup or pulldown base on configuration and lastly if the button will be read as input or interrupt.

Example

typedef struct{
     gpio_num_t pin;
     union{
         gpio_pullup_t up;
         gpio_pulldown_t down;
     }pull_sel;
     void (*func)(void *arg);
}button_t;
