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:

Function Documentation

uint32_t bsp_button_is_pressed ( uint32_t  button,
bool *  p_state 
)

Function for checking buttons states.

This function for checking if the button is pressed.

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_SUCCESSButton state was successfully read.
NRF_ERROR_INVALID_PARAMInvalid button ID.
uint32_t bsp_buttons_enable ( uint32_t  buttons)

Function for enabling specified buttons (others are disabled).

This function enables the specified buttons and configures them to be scanned. All other buttons are disabled (inactive).

Parameters
[in]buttonsButtons to be enabled, encoded as bits (bit 0 = button 0, bit 1 = button 1, etc).
Return values
NRF_SUCCESSSuccessfully enabled.
uint32_t bsp_buttons_state_get ( uint32_t *  p_buttons_state)

Function for getting buttons states.

This function allows to get the state of all buttons.

Parameters
[in]p_buttons_stateThis 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_SUCCESSButtons state was successfully read.
uint32_t bsp_event_to_button_assign ( uint32_t  button,
bsp_event_t  event 
)

Function for assigning specific event to button.

This function allows redefinition of standard events assigned to buttons. To unassign events, provide the event @ ref BSP_EVENT_NOTHING.

Parameters
[in]buttonButton ID to be redefined.
[in]eventEvent to be assigned to button.
Return values
NRF_SUCCESSEvent was successfully assigned to button.
NRF_ERROR_INVALID_PARAMInvalid button ID.
uint32_t bsp_indication_set ( bsp_indication_t  indicate)

Function for configuring indicators to required state.

This function indicates the required state by means of LEDs (if enabled).

Note
Alerts are indicated independently.
Parameters
[in]indicateState to be indicated.
Return values
NRF_SUCCESSState was successfully indicated.
NRF_ERROR_NO_MEMInternal timer operations queue was full.

uint32_t bsp_init ( uint32_t  type,
uint32_t  ticks_per_100ms,
bsp_event_callback_t  callback 
)

Function for initializing BSP.

Initialize 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:
Parameters
[in]typeType of peripherals used.
[in]ticks_per_100msNumber of RTC ticks for 100 ms.
[in]callbackFunction to be called when button press/event is detected.
Return values
