NOPSPIOutput< _DATA_PIN, _CLOCK_PIN, _SPI_CLOCK_DIVIDER > Class Template Reference

Detailed Description

template<uint8_t _DATA_PIN, uint8_t _CLOCK_PIN, uint32_t _SPI_CLOCK_DIVIDER>
class NOPSPIOutput< _DATA_PIN, _CLOCK_PIN, _SPI_CLOCK_DIVIDER >

A nop/stub class, mostly to show the SPI methods that are needed/used by the various SPI chipset implementations.

Should be used as a definition for the set of methods that the spi implementation classes should use (since C++ doesn't support the idea of interfaces - it's possible this could be done with virtual classes, need to decide if i want that overhead)

Definition at line 18 of file fastspi_nop.h.

Public Member Functions
	NOPSPIOutput ()
	Default Constructor.
	NOPSPIOutput (Selectable *pSelect)
	Constructor with selectable.
void	init ()
	initialize the SPI subssytem
void	release ()
	release the CS select
void	select ()
	latch the CS select
void	setSelect (Selectable *pSelect)
	set the object representing the selectable
void	waitFully ()
	wait until all queued up data has been written
void	writeByte (uint8_t b)
	write a byte out via SPI (returns immediately on writing register)
void	writeBytes (uint8_t *data, int len)
	A full cycle of writing a raw block of data out, including select, release, and waiting.
void	writeBytesValue (uint8_t value, int len)
	A full cycle of writing a value for len bytes, including select, release, and waiting.
template<uint8_t FLAGS, class D, EOrder RGB_ORDER>
void	writePixels (PixelController< RGB_ORDER > pixels, void *context=NULL)
	write out pixel data from the given PixelController object
void	writeWord (uint16_t w)
	write a word out via SPI (returns immediately on writing register)

Static Public Member Functions
template<uint8_t BIT>
static void	writeBit (uint8_t b)
	not the most efficient mechanism in the world - but should be enough for sm16716 and friends
template<uint8_t BIT>
static void	writeBit (uint8_t b)
	write a single bit out, which bit from the passed in byte is determined by template parameter
static void	writeBytesValueRaw (uint8_t value, int len)
	A raw set of writing byte values, assumes setup/init/waiting done elsewhere (static for use by adjustment classes)
