Function Documentation

static int DebugIOCtl (  NUTDEVICE *  dev, int  req, void *  conf )

Handle I/O controls for debug device 0. The debug device doesn't support any. Returns: Always -1.

static int DebugInit (  NUTDEVICE *  dev  )

Initialize debug device 0. Returns: Always 0.

static int DebugWrite (  NUTFILE *  fp, CONST void *  buffer, int  len )

Send characters to debug device 0. A carriage return character will be automatically appended to any linefeed. Returns: Number of characters sent.

static NUTFILE * DebugOpen (  NUTDEVICE *  dev, CONST char *  name, int  mode, int  acc )

Open debug device 0. Returns: Pointer to a static NUTFILE structure.

static int DebugClose (  NUTFILE *  fp  )

Close debug device 0. Returns: Always 0.
