There are serval macros available to configure the behaviour of the GFX-Library.
HAL macros:
#define HAL_USE_GFX // enables the GDISP sub system. This is essentially needed to use the display
#define HAL_USE_TOUCHPAD // enables the TouchPad sub system. This is essentially needed to use the touchpad
GDISP macors:
#define GDISP_USE_GPIO // GDISP is connected to the MCU using GPIO interface, involves using lld_lcdWriteGPIO() and lld_lcdReadGPIO()
#define GDISP_USE_FSMC // GDISP is connected to the MCU using FSMC interface
#define GDISP_USE_SPI // GDISP is connected to the MCU using SPI interface
#define GDISP_SCREEN_WIDTH // defines width of panel in pixels. This is essentially needed to use the display
#define GDISP_SCREEN_HEIGHT // defines height of panel in pixels. This is essentailly needed to use the display
#define GDISP_NEED_MULTITHREAD // GDISP will be accessed across different threads -> thread safe mode
#define GDISP_NEED_CONTROL // must be set to TRUE if controll access to the LCD controller is needed, eg for changing orientation or power mode
TouchPad macros:
#define TOUCHPAD_NEED_MULTITHREAD // TouchPad will be accessed across different threads -> thread safe mode
#define TOUCHPAD_XY_INVERTED // output of tpReadX() and tpReadY() swapped - needed if touchpad writes swapped to touchpad controller
#define TOUCHPAD_STORE_CALIBRATION // calibration values can be stored if set to true. Therefore tpCalibration() is not neccessary to call on each reset. involves using lld_tpWriteCalibration() and lld_tpReadCalibration()
