Function Documentation

uint32_t bsp_button_is_pressed ( uint32_t  button,
bool *  p_state 
)

Function for checking buttons states.

This function checks if the button is pressed. If the button ID iss out of range, the function returns false.

Parameters
[in]buttonButton ID to check.
[in]p_stateThis variable will store the information whether the specified button is pressed (true) or not.
Return values
NRF_SUCCESSIf the button state was successfully read.
uint32_t bsp_buttons_disable ( void  )

Function for disabling all buttons.

After calling this function, no buttons will generate events when pressed, and no buttons will be able to wake the system up from sleep mode.

Return values
NRF_SUCCESSIf the buttons were successfully disabled.
NRF_ERROR_NOT_SUPPORTEDIf the board has no buttons or BSP_SIMPLE is defined.
Returns
A propagated error.
uint32_t bsp_buttons_enable ( void  )

Function for enabling all buttons.

After calling this function, all buttons will generate events when pressed, and all buttons will be able to wake the system up from sleep mode.

Note
Before calling this function, you must initiate the following required modules:
Parameters
[in]typeType of peripherals used.

After calling this function, only the buttons that are set to 1 in wakeup_buttons can be used to wake up the chip. If this function is not called before going to, sleep either all or no buttons can wake up the chip.

This function should only be called immediately before going into sleep.

Parameters
[in]wakeup_buttonsMask describing which buttons should be able to wake up the chip.
Return values
