setResolution()

void setResolution ( char const *  modeline, int  viewPortWidth = -1, int  viewPortHeight = -1, bool  doubleBuffered = false  )

inherited

Sets current resolution using linux-like modeline.

Modeline must have following syntax (non case sensitive):

"label" clock_mhz hdisp hsyncstart hsyncend htotal vdisp vsyncstart vsyncend vtotal (+HSync | -HSync) (+VSync | -VSync) [DoubleScan | QuadScan] [FrontPorchBegins | SyncBegins | BackPorchBegins | VisibleBegins] [MultiScanBlank]

In fabglconf.h there are macros with some predefined modelines for common resolutions. When MultiScanBlank and DoubleScan is specified then additional rows are not repeated, but just filled with blank lines.

Parameters

modeline	Linux-like modeline as specified above.
viewPortWidth	Horizontal viewport size in pixels. If less than zero (-1) it is sized to modeline visible area width.
viewPortHeight	Vertical viewport size in pixels. If less then zero (-1) it is sized to maximum allocable.
doubleBuffered	if True allocates another viewport of the same size to use as back buffer. Make sure there is enough free memory.

Example:

// Use predefined modeline for 640x480@60Hz
VGAController.setResolution(VGA_640x480_60Hz);

// The same of above using modeline string
VGAController.setResolution("\"640x480@60Hz\" 25.175 640 656 752 800 480 490 492 525 -HSync -VSync");

// Set 640x382@60Hz but limit the viewport to 640x350
VGAController.setResolution(VGA_640x382_60Hz, 640, 350);
