Data Structures
struct	StatusSubsystem

Typedefs
typedef struct StatusSubsystem	StatusSubsystem

Functions
void	initializeStatusSubsystem (StatusSubsystem *pStatus)

Detailed Description

Applications may change how they choose to display status information. The default implementation here uses LEDs on NXP Freedom boards. You may swap out implementations as long as the "Required" methods and states are retained.

Definition in file status.h.

Typedef Documentation

typedef struct StatusSubsystem StatusSubsystem

StatusSubsystem() provides an object-like interface for communicating status to the user.

Function Documentation

void initializeStatusSubsystem

(

StatusSubsystem *

pStatus

)

initializeStatusSubsystem() should be called once at startup to initialize the data structure and to put hardware into the proper state for communicating status.

Parameters

pStatus

pointer to the status subsystem
