begin() [4/4]

void begin	(	SPIClass *	spi,
		int	DC,
		int	RESX = -1,
		int	CS = -1
	)

Initializes TFT display controller with Arduino style SPIClass object.

Parameters

spi	SPIClass object.
DC	GPIO of D/C signal (Data/Command).
RESX	GPIO of Reset signal (can be GPIO_UNUSED).
CS	GPIO of optional select signal (can be GPIO_UNUSED). Without CS signal it is impossible to share SPI channel with other devices.

Example:

fabgl::ST7789Controller DisplayController;

// SCK = 18, MOSI = 23, D/C = 22, RESX = 21
SPI.begin(18, -1, 23);
DisplayController.begin(&SPI, 22, 21);
DisplayController.setResolution(TFT_240x240);
