buttons in hello_sensor.c

Anonymous · ‎Dec 27, 2013

In hello_sensor.c, it says hello_sensor_interrupt_handler allows for three interrupt inputs where the buttons are defined as..

Button1 : value&0x01

Button2 : (value&0x02)>>1

Button3 : (value&0x04)>>2

When I press SW1 on the TAG board, this registers as Button1. If I were to add more buttons, how would I configure them as Button2 and Button3? I do realize I have to initialize as buttons/inputs/low/interrupt, but I am guessing there is more to it than that.

Thanks

The Tag board which is provided with SDK has only 1 button exposed. If you can wire GPIO pins, any unused GPIO can be used as buttons 2 or 3. You will need to modify hello_sensor_gpio_cfg to add the pin number and the flags. Check the button definition in WICED_Smart_SdkInlcudePlatformsBCM920732TAG_Q32platform.h. For button 2 flags would look something like that

#define GPIO_SETTINGS_BUTTON2 (GPIO_INPUT | GPIO_INIT_LOW | GPIO_BUTTON2 | GPIO_INT)
