LCDA35 Functions

Parameters

Rotation	The rotation of the display (eg FRAMEBUFFER_ROTATION_180)
Device	The SPI device that the ILI9486 and XPT2046 devices are connected to
DisplaySelect	The SPI chip select of the ILI9486 LCD controller
TouchSelect	The SPI chip select of the XPT2046 touch controller

Returns: The handle of the LCDA35 on success or INVALID_HANDLE_VALUE on failure

Note: This function will be called during startup if the parameter LCDA35_AUTOSTART is True Can be called multiple times to support more than one LCD display

◆ lcda35_stop()

BOOL STDCALL lcda35_stop ( HANDLE handle )

Stop the LCDA35 driver and deregister the Touch and Framebuffer devices associated with the display.
