class	DisplayDriver

class	DisplayDriverDSI
	Base driver for MIPI-DSI panels. All of the DSI PHY/lane bring-up, command-channel writes and video-timing/framebuffer scan-out are handled by an IDSIBus (dependency-injected, see the constructor below), not by this class - this class only turns ISurface writes into drawBitmap() calls and byte-swaps into the bus's expected native RGB565 order (see writeData()). That split is what makes this family portable: adding a platform means implementing IDSIBus once (see DSIBusESP32.h, the ESP32-P4 DBI+DPI path; DSIBusSTM32.h, STM32's HAL_DSI+LTDC path), while every panel subclass (ST7701Driver, ...) keeps working unchanged on every platform that has a bus. More...

class	DisplayDriverParallel8
	Common base class for 8-bit parallel ("Intel 8080"-style) TFT display drivers: 8 data lines (D0-D7), WR (write strobe), RD (read strobe, unused - this class only writes), RS/DC (command vs. data) and CS. This is the bus MCUFRIEND-style shields and many 40-pin parallel TFT breakout boards use, wired straight to 8 GPIOs rather than through SPI/QSPI - no dedicated bus peripheral is assumed, every data line and the WR strobe is bit-banged via digitalWrite(), the same portable approach TinyGPU/Input/TouchDriverArduino.h's TouchDriverBitBang uses for a resistive touch panel's four GPIO pins. This trades throughput (one digitalWrite() per bit, per byte) for working unmodified on any Arduino core - a hardware-accelerated 8080 driver (e.g. ESP32's LCD_CAM/ esp_lcd_panel_io_i80) would be faster but ties the implementation to one platform's peripheral, the same tradeoff DisplayDriverQSPI.h already makes explicitly for ESP32-only QSPI. More...

class	DisplayDriverParallel8ESP32
	Hardware-accelerated 8-bit parallel ("Intel 8080"-style) TFT display driver for ESP32-family targets, built on ESP-IDF's esp_lcd panel-IO layer - the same layer DisplayDriverQSPI.h uses for QSPI, just pointed at a different underlying peripheral. Where DisplayDriverSPI.h's hardware-parallel counterpart (DisplayDriverParallel8.h) bit-bangs D0-D7 one digitalWrite() per bit, this class drives the bus via DMA through whichever peripheral the target actually has: More...

class	DisplayDriverParallel8RP2040
	RP2040 PIO/DMA-accelerated 8-bit parallel ("Intel 8080"-style) TFT display driver. D0-D7 and WR are driven by one PIO state machine (see kLcd8080WriteProgram above) instead of bit-banged via digitalWrite() - see DisplayDriverParallel8.h for the portable bit-banged version this mirrors, and DisplayDriverParallel8ESP32.h for the equivalent ESP32 LCD_CAM/PARLIO-peripheral version. DC/CS/RST stay on plain GPIO (Arduino pinMode()/digitalWrite()), same as those two. More...

class	DisplayDriverQSPI
	Base driver for QSPI ("4-wire quad SPI") TFT panels: 1 clock, 1 chip-select, 4 data lines, no separate D/C pin. Used by a family of compact panel controllers (NV3041A, ST77916, CO5300, SH8601, AXS15231B, ...) that all speak a de-facto-standardized QSPI wire protocol - see IQSPIBus.h for the exact 32-bit command-frame/data layout. More...

class	DisplayDriverSDL
	Display class for rendering a Surface<RGB565> using the SDL2 library. This class can be used to display the contents of a TinyGPU Surface<RGB565> on a desktop environment for testing and debugging purposes. More...

class	DisplayDriverSPI
	Common base class for SPI-based display drivers. More...

class	DisplayDriverSTM32F723Discovery
	DisplayDriver<RGB565> wrapping the stm32f723-disco library's `LCD` class - the library owns the panel's init sequence and pixel output entirely (STM32Cube BSP driving the STM32F723's FMC peripheral), so this class is a thin adapter rather than a bus-level driver like DisplayDriverSPI/QSPI/DSI. Fixed 240x240 resolution - the panel is square, so width()/height() don't change with orientation. More...

class	DisplayDriverTFTeSPI
	Display driver that renders a TinyGPU surface through Bodmer's TFT_eSPI (https://github.com/Bodmer/TFT_eSPI) instead of one of this library's own SPI panel drivers (DisplayDriverSPI/QSPI/DSI) - useful if you already have a working TFT_eSPI `User_Setup.h` for your panel and would rather reuse it than duplicate the same init sequence/pin wiring here. More...

class	DSIBusESP32
	IDSIBus backend for ESP32-P4, built on ESP-IDF's DBI (command channel) + DPI (video-timing channel) split - the interface ESP32-P4 exposes for DSI LCDs. A DPI panel has no address-window/RAMWR concept: `esp_lcd_new_panel_dpi()` allocates a screen-sized, DMA-scanned framebuffer up front, and `esp_lcd_panel_draw_bitmap()` writes straight into a rect of it - the continuously-running DPI bridge just scans whatever's currently there. More...

class	DSIBusSTM32
	IDSIBus backend for STM32 parts with a DSI host + LTDC (F469/ F479, F769/F779, H747/H757, U5x9, ...), built on STM32Cube HAL's HAL_DSI_* (command channel, adapted/video-mode DSI wrapper) and HAL_LTDC_* (the pixel-timing generator/framebuffer scanner DSI sits in front of on these parts - conceptually the same role ESP32-P4's DPI peripheral plays for DSIBusESP32).

class	IDSIBus
	Abstraction over the transport used by DisplayDriverDSI (see TinyGPU/Drivers/DisplayDriverDSI.h) to talk to MIPI-DSI panels: a low-speed command channel (DCS/vendor register writes, used for the panel's init sequence) plus a continuously-scanned video channel backed by a framebuffer that draws address into directly - there's no address-window/RAMWR concept the way SPI/QSPI panels have. More...

More...

class	ISurface
	Abstract framebuffer and drawing interface for TinyGPU surfaces. More...

	Portable, software-driven IQSPIBus backend built only on pinMode()/digitalWrite() - works on any Arduino core, notably RP2040 and STM32, neither of which exposes a hardware peripheral for this panel family's quad-SPI protocol the way ESP-IDF's esp_lcd does for ESP32 (see QSPIBusESP32.h): More...

class	QSPIBusESP32
	Hardware-accelerated IQSPIBus backend for ESP32, built on top of ESP-IDF's esp_lcd_new_panel_io_spi(quad_mode=1) - DMA-driven, with a persistent scratch buffer and completion callback for writeColor() (see that method's doc comment for why: esp_lcd_panel_io_tx_color() is asynchronous).

Enumeration Type Documentation

◆ DisplayRotation

enum class DisplayRotation

strong

Abstract base class for display drivers.

Defines the interface for initializing the display, setting the address window, and writing pixel data from a Surface. Specific display drivers (e.g. SPI, SDL) should inherit from this and implement the virtual methods. Common rotation values for rectangular display drivers (row/column exchange plus optional axis mirroring) - shared here, rather than duplicated as a nested enum per concrete driver (as ILI9341Driver/ ILI9342Driver used to each define their own, identical, copy), so generic code holding only a DisplayDriver<RGB_T>& (e.g. an LCDBoard's display()) can call setRotation() without knowing the concrete driver type. Concrete drivers keep a using Rotation = tinygpu::DisplayRotation; alias so existing code written against e.g. ILI9341Driver<RGB565>:: Rotation still compiles unchanged. Named DisplayRotation (not just Rotation) to avoid colliding with the differently-shaped touch tinygpu::Rotation (Deg0/Deg90/Deg180/Deg270) in TouchDriver.h.

Function Documentation

◆ delay() [1/2]

void delay ( uint32_t ms )

inline

Blocks the calling task for ms milliseconds via FreeRTOS - the ESP-IDF-native equivalent of Arduino's delay().

◆ delay() [2/2]

void delay ( unsigned long ms )

inline

Blocks the calling thread for ms milliseconds, matching Arduino's delay().

◆ digitalRead()

int digitalRead ( int pin )

inline

Reads a GPIO input level, matching Arduino's digitalRead().

◆ digitalWrite()

void digitalWrite	(	int	pin,
		int	value
	)

inline

Sets a GPIO output level, matching Arduino's digitalWrite().

◆ findSprite()

Vector< std::unique_ptr< SpriteInfo< RGB_T, SurfaceT > > >::iterator findSprite	(	Vector< std::unique_ptr< SpriteInfo< RGB_T, SurfaceT > > > &	sprites,
		SpriteInfo< RGB_T, SurfaceT > &	spriteInfo
	)

inline

Finds the iterator to a sprite within a sprite list, shared by FrameBuffer and SpriteDisplay.

◆ isLandscapeFamily()

bool isLandscapeFamily ( DisplayRotation r )

inline

True for the landscape family (kLandscape/kLandscapeFlipped) - false for portrait (kPortrait/kPortraitFlipped) or kNone. The landscape family has its row/column addressing exchanged relative to portrait (MV bit, on MIPI-DCS-style controllers), which is what makes width()/height() swap between the two families - a same-family rotation (e.g. kLandscape to kLandscapeFlipped, a 180 degree flip) only changes scan direction, not addressable width/height.

◆ millis()

unsigned long millis ( )

inline

Milliseconds since the epoch, from a monotonic (steady) clock - not "time since boot" the way Arduino's millis() is, but that distinction never matters here: GestureDetector.h only ever subtracts two millis() calls to get an elapsed duration, never reads the absolute value.

Milliseconds since boot, matching Arduino's millis() (wraps the same way a 32-bit millisecond counter would, since esp_timer's underlying 64-bit microsecond count is truncated to unsigned long here).

◆ operator!=() [1/2]

bool operator!=	(	const tinygpu::RGB565 &	lhs,
		const tinygpu::RGB565 &	rhs
	)

inline

◆ operator!=() [2/2]

bool operator!=	(	const tinygpu::RGB888 &	lhs,
		const tinygpu::RGB888 &	rhs
	)

inline

◆ pinMode()

void pinMode	(	int	pin,
		int	mode
	)

inline

Configures a GPIO's direction/pull, matching Arduino's pinMode(). A negative pin (this library's "not wired up" sentinel throughout Drivers/Input) is silently ignored, exactly like the callers already assume when they guard on pin >= 0 before calling at all - and harmlessly for the few call sites that don't bother guarding.

◆ renderTransformedSprite()

Surface< RGB_T > renderTransformedSprite	(	const SpriteInfo< RGB_T, SurfaceT > &	spriteInfo,
		IFont< RGB_T > &	font
	)

inline

Renders spriteInfo's pristine sprite image at its currently requested scale and rotation (SpriteInfo::currentScale/currentAngleDegrees, set by scaleSprite()/rotateSprite() - see FrameBuffer.h/SpriteDisplay.h) in one combined pass, shared by FrameBuffer and SpriteDisplay.

This always starts over from the pristine original, never from spriteInfo.currentSprite() (the previous frame's already-transformed raster) - scaleSpriteImage()/rotateSpriteImage() use nearest-neighbor sampling with no interpolation, so repeatedly transforming an already-transformed raster compounds resampling artifacts frame after frame until the image degenerates into a solid blob within seconds (confirmed empirically: an 18x18 circle sprite scaled/rotated every frame that way fills its entire 40x40 max buffer within ~10 frames). Re-deriving from the pristine source every time is also the only way to support an absolute scale/angle contract at all - scaleSprite(info, 1.0) must be able to undo a previous scaleSprite(info, 1.3), which is impossible if 1.3x has already been baked irreversibly into the stored raster.

◆ rotateSpriteImage()

Surface< RGB_T > rotateSpriteImage	(	const ISurface< RGB_T > &	source,
		float	angleDegrees,
		RGB_T	fillColor,
		IFont< RGB_T > &	font
	)

inline

Returns a rotated copy of a sprite image, filling empty space with fillColor. Shared by FrameBuffer and SpriteDisplay.

◆ scaleSpriteImage()

Surface< RGB_T > scaleSpriteImage	(	const ISurface< RGB_T > &	source,
		float	scale,
		IFont< RGB_T > &	font
	)

inline

Returns a scaled copy of a sprite image, shared by FrameBuffer and SpriteDisplay.

◆ toString()

const char * toString ( GestureType type )

inline

Human-readable name for a GestureType, useful for logging.
