void glXPutBitmap( int x, int y, int bmWidth,
int bmHeight, unsigned long bmPtr )
Displays a bitmap stored in xmem on the LCD. For bitmaps stored in
root memory, use glPutBitmap.
PARAMETERS: x is the x coordinate of the bitmap left edge.
y
is the y coordinate of the bitmap top edge.
bmWidth
is the width of the bitmap.
bmHeight
is the height of the bitmap.
bmPtr
is a pointer to the bitmap. The bitmap format is a column with
the major byte aligned for each column.
KP_OP71.LIB
void kpInit( int (*changeFn)() )
Initializes the kp module. Call this function before calling other
functions in this library. If the default keypad scanning routine will be
used, use kpDefInit instead of this function.
PARAMETER: changeFn is a pointer to a function that will be called
when the driver detects a change (when kpScanState is called). Two
arguments are passed to the callback function. The first argument is a
pointer to an array that indicates the current state of the keypad. The
second is a pointer to an array that indicates what keypad positions are
changed and detected by kpScanState. The byte offset in the array
represents the line pulled high (row number), and the bits in a byte
represents the positions (column number) read back.
int kpScanState()
Scans the keypad and detects any changes to the keypad status. If
kpInit
is called with a non-NULL function pointer, that function will
be called with the state of the keypad. This function should be called
periodically to scan for keypad activities.
RETURN VALUE: 0 if there is no change to the keypad, non-zero if
there is any change to the keypad.
