	Call before issuing command(s) or data to display. Performs chip-select (if required) and starts an SPI transaction (if using hardware SPI and transactions are supported). Required for all display types; not an SPI-specific function.
void	endWrite (void)
	Call after issuing command(s) or data to display. Performs chip-deselect (if required) and ends an SPI transaction (if using hardware SPI and transactions are supported). Required for all display types; not an SPI-specific function.
void	sendCommand (uint8_t commandByte, uint8_t *dataBytes, uint8_t numDataBytes)
	Adafruit_SPITFT Send Command handles complete sending of commands and data.
void	sendCommand (uint8_t commandByte, const uint8_t *dataBytes=NULL, uint8_t numDataBytes=0)
	Adafruit_SPITFT Send Command handles complete sending of commands and data.
void	sendCommand16 (uint16_t commandWord, const uint8_t *dataBytes=NULL, uint8_t numDataBytes=0)
	Adafruit_SPITFT sendCommand16 handles complete sending of commands and data for 16-bit parallel displays. Currently somewhat rigged for the NT35510, which has the odd behavior of wanting commands 16-bit, but subsequent data as 8-bit values, despite the 16-bit bus (high byte is always 0). Also seems to require issuing and incrementing address with each transfer.
uint8_t	readcommand8 (uint8_t commandByte, uint8_t index=0)
	Read 8 bits of data from display configuration memory (not RAM). This is highly undocumented/supported and should be avoided, function is only included because some of the examples use it.
uint16_t	readcommand16 (uint16_t addr)
	Read 16 bits of data from display register. For 16-bit parallel displays only.
void	writePixel (int16_t x, int16_t y, uint16_t color)
	Draw a single pixel to the display at requested coordinates. Not self-contained; should follow a startWrite() call.
void	writePixels (uint16_t *colors, uint32_t len, bool block=true, bool bigEndian=false)
	Issue a series of pixels from memory to the display. Not self- contained; should follow startWrite() and setAddrWindow() calls.
void	writeColor (uint16_t color, uint32_t len)
	Issue a series of pixels, all the same color. Not self- contained; should follow startWrite() and setAddrWindow() calls.
void	writeFillRect (int16_t x, int16_t y, int16_t w, int16_t h, uint16_t color)
	Draw a filled rectangle to the display. Not self-contained; should follow startWrite(). Typically used by higher-level graphics primitives; user code shouldn't need to call this and is likely to use the self-contained fillRect() instead. writeFillRect() performs its own edge clipping and rejection; see writeFillRectPreclipped() for a more 'raw' implementation.
void	writeFastHLine (int16_t x, int16_t y, int16_t w, uint16_t color)
	Draw a horizontal line on the display. Performs edge clipping and rejection. Not self-contained; should follow startWrite(). Typically used by higher-level graphics primitives; user code shouldn't need to call this and is likely to use the self- contained drawFastHLine() instead.
void	writeFastVLine (int16_t x, int16_t y, int16_t h, uint16_t color)
	Draw a vertical line on the display. Performs edge clipping and rejection. Not self-contained; should follow startWrite(). Typically used by higher-level graphics primitives; user code shouldn't need to call this and is likely to use the self- contained drawFastVLine() instead.
void	writeFillRectPreclipped (int16_t x, int16_t y, int16_t w, int16_t h, uint16_t color)
	A lower-level version of writeFillRect(). This version requires all inputs are in-bounds, that width and height are positive, and no part extends offscreen. NO EDGE CLIPPING OR REJECTION IS PERFORMED. If higher-level graphics primitives are written to handle their own clipping earlier in the drawing process, this can avoid unnecessary function calls and repeated clipping operations in the lower-level functions.
void	dmaWait (void)
	Wait for the last DMA transfer in a prior non-blocking writePixels() call to complete. This does nothing if DMA is not enabled, and is not needed if blocking writePixels() was used (as is the default case).
bool	dmaBusy (void) const
	Check if DMA transfer is active. Always returts false if DMA is not enabled.
void	swapBytes (uint16_t *src, uint32_t len, uint16_t *dest=NULL)
	Swap bytes in an array of pixels; converts little-to-big or big-to-little endian. Used by writePixels() below in some situations, but may also be helpful for user code occasionally.
void	drawPixel (int16_t x, int16_t y, uint16_t color)
	Draw a single pixel to the display at requested coordinates. Self-contained and provides its own transaction as needed (see writePixel(x,y,color) for a lower-level variant). Edge clipping is performed here.
void	fillRect (int16_t x, int16_t y, int16_t w, int16_t h, uint16_t color)
	Draw a filled rectangle to the display. Self-contained and provides its own transaction as needed (see writeFillRect() or writeFillRectPreclipped() for lower-level variants). Edge clipping and rejection is performed here.
void	drawFastHLine (int16_t x, int16_t y, int16_t w, uint16_t color)
	Draw a horizontal line on the display. Self-contained and provides its own transaction as needed (see writeFastHLine() for a lower-level variant). Edge clipping and rejection is performed here.
void	drawFastVLine (int16_t x, int16_t y, int16_t h, uint16_t color)
	Draw a vertical line on the display. Self-contained and provides its own transaction as needed (see writeFastHLine() for a lower- level variant). Edge clipping and rejection is performed here.
void	pushColor (uint16_t color)
	Essentially writePixel() with a transaction around it. I don't think this is in use by any of our code anymore (believe it was for some older BMP-reading examples), but is kept here in case any user code relies on it. Consider it DEPRECATED.
void	drawRGBBitmap (int16_t x, int16_t y, uint16_t *pcolors, int16_t w, int16_t h)
	Draw a 16-bit image (565 RGB) at the specified (x,y) position. For 16-bit display devices; no color reduction performed. Adapted from https://github.com/PaulStoffregen/ILI9341_t3 by Marc MERLIN. See examples/pictureEmbed to use this. 5/6/2017: function name and arguments have changed for compatibility with current GFX library and to avoid naming problems in prior implementation. Formerly drawBitmap() with arguments in different order. Handles its own transaction and edge clipping/rejection.
void	invertDisplay (bool i)
	Invert the colors of the display (if supported by hardware). Self-contained, no transaction setup required.
uint16_t	color565 (uint8_t r, uint8_t g, uint8_t b)
	Given 8-bit red, green and blue values, return a 'packed' 16-bit color value in '565' RGB format (5 bits red, 6 bits green, 5 bits blue). This is just a mathematical operation, no hardware is touched.
void	spiWrite (uint8_t b)
	Issue a single 8-bit value to the display. Chip-select, transaction and data/command selection must have been previously set – this ONLY issues the byte. This is another of those functions in the library with a now-not-accurate name that's being maintained for compatibility with outside code. This function is used even if display connection is parallel.
void	writeCommand (uint8_t cmd)
	Write a single command byte to the display. Chip-select and transaction must have been previously set – this ONLY sets the device to COMMAND mode, issues the byte and then restores DATA mode. There is no corresponding explicit writeData() function – just use spiWrite().
uint8_t	spiRead (void)
	Read a single 8-bit value from the display. Chip-select and transaction must have been previously set – this ONLY reads the byte. This is another of those functions in the library with a now-not-accurate name that's being maintained for compatibility with outside code. This function is used even if display connection is parallel.
void	write16 (uint16_t w)
	Issue a single 16-bit value to the display. Chip-select, transaction and data/command selection must have been previously set – this ONLY issues the word. Thus operates ONLY on 'wide' (16-bit) parallel displays!
void	writeCommand16 (uint16_t cmd)
	Write a single command word to the display. Chip-select and transaction must have been previously set – this ONLY sets the device to COMMAND mode, issues the byte and then restores DATA mode. This operates ONLY on 'wide' (16-bit) parallel displays!
uint16_t	read16 (void)
	Read a single 16-bit value from the display. Chip-select and transaction must have been previously set – this ONLY reads the byte. This operates ONLY on 'wide' (16-bit) parallel displays!
void	SPI_WRITE16 (uint16_t w)
	Issue a single 16-bit value to the display. Chip-select, transaction and data/command selection must have been previously set – this ONLY issues the word. Despite the name, this function is used even if display connection is parallel; name was maintaned for backward compatibility. Naming is also not consistent with the 8-bit version, spiWrite(). Sorry about that. Again, staying compatible with outside code.
void	SPI_WRITE32 (uint32_t l)
	Issue a single 32-bit value to the display. Chip-select, transaction and data/command selection must have been previously set – this ONLY issues the longword. Despite the name, this function is used even if display connection is parallel; name was maintaned for backward compatibility. Naming is also not consistent with the 8-bit version, spiWrite(). Sorry about that. Again, staying compatible with outside code.
void	SPI_CS_HIGH (void)
	Set the chip-select line HIGH. Does NOT check whether CS pin is set (>=0), that should be handled in calling function. Despite function name, this is used even if the display connection is parallel.
void	SPI_CS_LOW (void)
	Set the chip-select line LOW. Does NOT check whether CS pin is set (>=0), that should be handled in calling function. Despite function name, this is used even if the display connection is parallel.
void	SPI_DC_HIGH (void)
	Set the data/command line HIGH (data mode).
void	SPI_DC_LOW (void)
	Set the data/command line LOW (command mode).
void	drawRGBBitmap (int16_t x, int16_t y, const uint16_t bitmap[], int16_t w, int16_t h)
	Draw a PROGMEM-resident 16-bit image (RGB 5/6/5) at the specified (x,y) position. For 16-bit display devices; no color reduction performed.
void	drawRGBBitmap (int16_t x, int16_t y, const uint16_t bitmap[], const uint8_t mask[], int16_t w, int16_t h)
	Draw a PROGMEM-resident 16-bit image (RGB 5/6/5) with a 1-bit mask (set bits = opaque, unset bits = clear) at the specified (x,y) position. BOTH buffers (color and mask) must be PROGMEM-resident. For 16-bit display devices; no color reduction performed.
void	drawRGBBitmap (int16_t x, int16_t y, uint16_t *bitmap, uint8_t *mask, int16_t w, int16_t h)
	Draw a RAM-resident 16-bit image (RGB 5/6/5) with a 1-bit mask (set bits = opaque, unset bits = clear) at the specified (x,y) position. BOTH buffers (color and mask) must be RAM-resident. For 16-bit display devices; no color reduction performed.

void	begin (uint32_t freq=0)
	Initialize ST77xx chip. Connects to the ST77XX over SPI and sends initialization procedure commands.
void	begin (uint32_t freq, bool reset)
	Initialize ST77xx chip. Connects to the ST77XX over SPI and sends initialization procedure commands.
void	commonInit (const uint8_t *cmdList)
	Initialization code common to all ST77XX displays.
void	displayInit (const uint8_t *addr)
	Companion code to the initiliazation tables. Reads and issues a series of LCD commands stored in PROGMEM byte array.
void	setColRowStart (int8_t col, int8_t row)
	Set origin of (0,0) of display with offsets.
Protected Member Functions inherited from Adafruit_SPITFT
void	SPI_MOSI_HIGH (void)
	Set the software (bitbang) SPI MOSI line HIGH.
void	SPI_MOSI_LOW (void)
	Set the software (bitbang) SPI MOSI line LOW.
void	SPI_SCK_HIGH (void)
	Set the software (bitbang) SPI SCK line HIGH.
void	SPI_SCK_LOW (void)
	Set the software (bitbang) SPI SCK line LOW.
bool	SPI_MISO_READ (void)
	Read the state of the software (bitbang) SPI MISO line.
void	SPI_BEGIN_TRANSACTION (void)
	Start an SPI transaction if using the hardware SPI interface to the display. If using an earlier version of the Arduino platform (before the addition of SPI transactions), this instead attempts to set up the SPI clock and mode. No action is taken if the connection is not hardware SPI-based. This does NOT include a chip-select operation – see startWrite() for a function that encapsulated both actions.
void	SPI_END_TRANSACTION (void)
	End an SPI transaction if using the hardware SPI interface to the display. No action is taken if the connection is not hardware SPI-based or if using an earlier version of the Arduino platform (before the addition of SPI transactions). This does NOT include a chip-deselect operation – see endWrite() for a function that encapsulated both actions.
void	TFT_WR_STROBE (void)
	Set the WR line LOW, then HIGH. Used for parallel-connected interfaces when writing data.
void	TFT_RD_HIGH (void)
	Set the RD line HIGH. Used for parallel-connected interfaces when reading data.
void	TFT_RD_LOW (void)
	Set the RD line LOW. Used for parallel-connected interfaces when reading data.
