Detailed Description

template<typename RGB_T = RGB565>
class tinygpu::ILI9341Driver8080ESP32< RGB_T >

Driver for ILI9341 8-bit parallel display controller, driven via ESP32's LCD_CAM/I80 or PARLIO peripheral (see DisplayDriverParallel8ESP32).

Same power/gamma/MADCTL init sequence as DisplayDriverSPI.h's ILI9341Driver (see that class's doc comment for provenance) - only the bus underneath differs.

Rotation

using Rotation = tinygpu::DisplayRotation

Constructor & Destructor Documentation

ILI9341Driver8080ESP32()

ILI9341Driver8080ESP32 ( int8_t  d0, int8_t  d1, int8_t  d2, int8_t  d3, int8_t  d4, int8_t  d5, int8_t  d6, int8_t  d7, int8_t  wr, int8_t  dc, int8_t  cs, Rotation  rotation = Rotation::kNone, uint32_t  pclkHz = 20000000, size_t  nativeWidth = 240, size_t  nativeHeight = 320  )

inline

Parameters

nativeWidth/nativeHeight

the panel's physical resolution in its native (portrait, MV bit clear) orientation - 240x320 is the common ILI9341 module size and the default; pass your panel's real values if it differs.

Member Function Documentation

begin()

bool begin ( )

inlineoverridevirtual

Implements DisplayDriver< RGB_T >.

height()

size_t height ( ) const

inlineoverridevirtual

Reimplemented from DisplayDriverParallel8ESP32< RGB_T >.

madctlForRotation()

static uint8_t madctlForRotation ( Rotation  rotation )

inlinestaticprotected

rotation()

Rotation rotation ( ) const

inline

setInvertColor()

void setInvertColor ( bool  invert )

inline

See DisplayDriverSPI.h's ILI9341Driver::setInvertColor() - same panel quirk, same fix, just re-sent over this bus's begin() instead.

setRotation()

void setRotation ( Rotation  rotation )

inlineoverridevirtual

Changes the panel's rotation after begin(). Default no-op, for drivers with no such concept (e.g. a fixed-orientation panel, or a desktop/SDL backend) - concrete SPI drivers (ILI9341Driver, ILI9342Driver) override this to reprogram MADCTL.

Reimplemented from DisplayDriver< RGB_T >.

width()

size_t width ( ) const

inlineoverridevirtual

Current addressable panel width/height in pixels - for a driver that supports setRotation(), these reflect the current rotation (landscape vs portrait swaps them; see isLandscapeFamily()), not necessarily the panel's native/physical orientation. Callers that need to lay out content (e.g. OutputTinyGPU's scale_to_fit target, or clearScreen()'s band loop) should read these fresh rather than caching their own copy, so a setRotation() call is picked up automatically without needing separate bookkeeping.

Reimplemented from DisplayDriverParallel8ESP32< RGB_T >.
