Detailed Description

Custom Button structure to automate button setup.

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 gpio; // gpio number
     union{
         gpio_pullup_t up; //pullup
         gpio_pulldown_t down; //pulldown
     }pull_sel; //select configuration 
     void (*func)(void *arg); //gpio interrupt routine
}Button;
