pitft28_start()

HANDLE STDCALL pitft28_start	(	uint32_t	rotation,
		char *	device,
		uint16_t	displayselect,
		uint16_t	touchselect )

Start the PiTFT28 driver and register the Touch, Backlight (GPIO) and Framebuffer devices associated with the display.

PiTFT28 Functions

Parameters

Rotation	The rotation of the display (eg FRAMEBUFFER_ROTATION_180)
Device	The SPI device that the ILI9340 and STMPE610 devices are connected to
DisplaySelect	The SPI chip select of the ILI9340 LCD controller
TouchSelect	The SPI chip select of the STMPE610 touch controller

Returns

The handle of the PiTFT28 on success or INVALID_HANDLE_VALUE on failure

Note

This function will be called during startup if the parameter PITFT28_AUTOSTART is True Can be called multiple times to support more than one PiTFT LCD display

Replaced by PiTFT28ResistiveStart to accommodate capacitive display option

pitft28_resistive_start()

HANDLE STDCALL pitft28_resistive_start	(	uint32_t	rotation,
		char *	device,

Device	The SPI device that the ILI9340 and STMPE610 devices are connected to
DisplaySelect	The SPI chip select of the ILI9340 LCD controller
TouchSelect	The SPI chip select of the STMPE610 touch controller

Returns

The handle of the PiTFT28 on success or INVALID_HANDLE_VALUE on failure

Note

This function will be called during startup if the parameter PITFT28_AUTOSTART is True Can be called multiple times to support more than one PiTFT LCD display

pitft28_capacitive_start()
