Detailed Description
LCDBoard wrapping a single TFT_eSPI instance, shared between its DisplayDriverTFTeSPI and (optional) TouchDriverTFTeSPI.
All panel-specific configuration (controller, pins, SPI frequency, ...) is TFT_eSPI's own User_Setup.h/User_Setup_Select.h job, same as any other TFT_eSPI sketch - width/height are still passed to the constructor (rather than read from TFT_eSPI) because, like every other LCDBoard here, callers may need them before begin() runs.
Touch is opt-in via the constructor's hasTouch flag (many TFT_eSPI panels have no touch hardware at all) - touch() returns nullptr when disabled. When enabled, use tft() to reach TFT_eSPI's own touch calibration (tft().setTouch(calData), from tft().calibrateTouch(...) or a hardcoded panel-specific array) before calling begin() - TFT_eSPI owns touch calibration entirely, the same "driver does not own
bus/calibration setup, the application does" split TouchDriverArduino.h's drivers use for their own SPI/I2C buses.
No backlight/I2S/LED pin handling here - TFT_eSPI's own User_Setup.h covers the backlight pin (TFT_BL) if your panel needs one driven manually; i2s()/led() report "not present" (every field -1) and backlightPin() is -1, the same as LCDBoardDesktopSDL.

Member Function Documentation
◆ begin()
|

Initializes TFT_eSPI (via DisplayDriverTFTeSPI::begin()) and, if hasTouch was set, the touch driver.
Implements LCDBoard.
◆ display()
|
inlineoverridevirtual |
The board's display driver.
Implements LCDBoard.
◆ height()
|
inlineoverridevirtual |
Panel height in pixels, as passed to the constructor.
Implements LCDBoard.
◆ i2s()
|
inlineoverridevirtual |
No I2S bus tracked here - every field is -1.
Implements LCDBoard.
◆ led()
|
inlineoverridevirtual |
No LED tracked here - every field is -1.
Implements LCDBoard.
◆ tft()
|
inline |
Direct access to the underlying TFT_eSPI instance - e.g. for touch calibration (see class comment) or any TFT_eSPI feature this driver doesn't wrap.
◆ touch()
|
inlineoverridevirtual |
The board's touch controller, or nullptr if hasTouch was false.
Implements LCDBoard.
◆ width()
|
inlineoverridevirtual |
Panel width in pixels, as passed to the constructor.
Implements LCDBoard.
