Functions
void	ft5336_Init (uint16_t DeviceAddr)
	Initialize the ft5336 communication bus from MCU to FT5336 : ie I2C channel initialization (if required). More...
void	ft5336_Reset (uint16_t DeviceAddr)
	Software Reset the ft5336. More...
uint16_t	ft5336_ReadID (uint16_t DeviceAddr)
	Read the ft5336 device ID, pre initialize I2C in case of need to be able to read the FT5336 device ID, and verify this is a FT5336. More...
void	ft5336_TS_Start (uint16_t DeviceAddr)
	Configures the touch Screen IC device to start detecting touches. More...
uint8_t	ft5336_TS_DetectTouch (uint16_t DeviceAddr)
	Return if there is touches detected or not. Try to detect new touches and forget the old ones (reset internal global variables). More...
void	ft5336_TS_GetXY (uint16_t DeviceAddr, uint16_t *X, uint16_t *Y)
	Get the touch screen X and Y positions values Manage multi touch thanks to touch Index global variable 'ft5336_handle.currActiveTouchIdx'. More...
void	ft5336_TS_EnableIT (uint16_t DeviceAddr)
	Configure the FT5336 device to generate IT on given INT pin connected to MCU as EXTI. More...
void	ft5336_TS_DisableIT (uint16_t DeviceAddr)
	Configure the FT5336 device to stop generating IT on the given INT pin connected to MCU as EXTI. More...
uint8_t	ft5336_TS_ITStatus (uint16_t DeviceAddr)
	Get IT status from FT5336 interrupt status registers Should be called Following an EXTI coming to the MCU to know the detailed reason of the interrupt. More...
void	ft5336_TS_ClearIT (uint16_t DeviceAddr)
	Clear IT status in FT5336 interrupt status clear registers Should be called Following an EXTI coming to the MCU. More...
void	ft5336_TS_GetGestureID (uint16_t DeviceAddr, uint32_t *pGestureId)
	Get the last touch gesture identification (zoom, move up/down...). More...
void	ft5336_TS_GetTouchInfo (uint16_t DeviceAddr, uint32_t touchIdx, uint32_t *pWeight, uint32_t *pArea, uint32_t *pEvent)
	Get the touch detailed informations on touch number 'touchIdx' (0..1) This touch detailed information contains : More...
