Detailed Description

BSP module.

This module provides a layer of abstraction from the board. It allows the user to indicate certain states on LEDs in a simple way. Module functionality can be modified by additional defines:

BSP_SIMPLE reduces functionality of this module to enable and read state of the buttons
BSP_UART_SUPPORT enables support for UART

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]	button	Button ID to check.
[in]	p_state	This variable will store the information whether the specified button is pressed (true) or not.

Return values

NRF_SUCCESS If 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_SUCCESS	If the buttons were successfully disabled.
NRF_ERROR_NOT_SUPPORTED	If 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.

Return values

NRF_SUCCESS	If the buttons were successfully enabled.

Function for getting buttons states.

This function allows to get the state of all buttons.

Parameters

[in] p_buttons_state This variable will store buttons state. Button 0 state is represented by bit 0 (1=pressed), Button 1 state by bit 1, and so on.

Return values

NRF_SUCCESS If buttons state was successfully read.

		uint32_t	ticks_per_100ms,
		bsp_event_callback_t	callback
	)

Function for initializing BSP.

The function initializes the board support package to allow state indication and button reaction. Default events are assigned to buttons.

Note

Before calling this function, you must initiate the following required modules:

Application Timer for LED support
GPIOTE Handler for button support
UART module for UART support

Parameters

[in]	type	Type of peripherals used.
[in]	ticks_per_100ms	Number of RTC ticks for 100 ms.
[in]	callback	Function to be called when button press/event is detected.

NRF_ERROR_INVALID_STATE	If button or GPIOTE has not been initialized.

uint32_t bsp_wakeup_buttons_set ( uint32_t wakeup_buttons )

Function for configuring wakeup buttons before going into sleep mode.

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_buttons Mask describing which buttons should be able to wake up the chip.
