REFHardwareSPIOutput< _DATA_PIN, _CLOCK_PIN, _SPI_CLOCK_DIVIDER > Class Template Reference

Detailed Description

template<fl::u8 _DATA_PIN, fl::u8 _CLOCK_PIN, fl::u32 _SPI_CLOCK_DIVIDER>
class REFHardwareSPIOutput< _DATA_PIN, _CLOCK_PIN, _SPI_CLOCK_DIVIDER >

A skeletal implementation of hardware SPI support.

Fill in the necessary code for init, waiting, and writing. The rest of the method implementations should provide a starting point, even if they're not the most efficient to start with

Public Member Functions
void	init ()
	initialize the SPI subssytem
void	release ()
	release the CS select
	SAMHArdwareSPIOutput (Selectable *pSelect)
	Constructor with selectable.
	SAMHardwareSPIOutput ()
	Default Constructor.
void	select ()
	latch the CS select
void	setSelect (Selectable *pSelect)
	set the object representing the selectable
template<class D>
void	writeBytes (FASTLED_REGISTER fl::u8 *data, int len)
	A full cycle of writing a value for len bytes, including select, release, and waiting.
void	writeBytes (FASTLED_REGISTER fl::u8 *data, int len)
	A full cycle of writing a value for len bytes, including select, release, and waiting.
void	writeBytesValue (fl::u8 value, int len)
	A full cycle of writing a value for len bytes, including select, release, and waiting.
template<fl::u8 FLAGS, class D, EOrder RGB_ORDER>
void	writePixels (PixelController< RGB_ORDER > pixels, void *context=NULL)
	write a block of uint8_ts out in groups of three.

Static Public Member Functions
static void	waitFully ()
	wait until all queued up data has been written
template<fl::u8 BIT>
static void	writeBit (fl::u8 b)
	write a single bit out, which bit from the passed in byte is determined by template parameter
static void	writeByte (fl::u8 b)
	write a byte out via SPI (returns immediately on writing register)
static void	writeBytesValueRaw (fl::u8 value, int len)
	A raw set of writing byte values, assumes setup/init/waiting done elsewhere.
static void	writeWord (uint16_t w)
	write a word out via SPI (returns immediately on writing register)
