configureLUT()

void fl::spi::ParallelDevice::configureLUT	(	const u32 *	set_masks,
		const u32 *	clear_masks )

Configure custom LUT (advanced)

Parameters

set_masks	Array of 256 set masks (GPIO pins to set high for each byte value)
clear_masks	Array of 256 clear masks (GPIO pins to clear low for each byte value)

Note

Default LUT maps byte bits directly to GPIO pins

Must be called before begin() or after begin() but before write()
