Macros
#define	FT6x06_MAX_INSTANCE   2

Functions
void	ft6x06_Init (uint16_t DeviceAddr)
	Initialize the ft6x06 communication bus from MCU to FT6206 : ie I2C channel initialization (if required). More...
void	ft6x06_Reset (uint16_t DeviceAddr)
	Software Reset the ft6x06. More...
uint16_t	ft6x06_ReadID (uint16_t DeviceAddr)
	Read the ft6x06 device ID, pre initialize I2C in case of need to be able to read the FT6206 device ID, and verify this is a FT6206. More...
void	ft6x06_TS_Start (uint16_t DeviceAddr)
	Configures the touch Screen IC device to start detecting touches It goes through an internal calibration process (Hw calibration sequence of the touch screen). More...
uint8_t	ft6x06_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	ft6x06_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 'ft6x06_handle.currActiveTouchIdx'. More...
void	ft6x06_TS_EnableIT (uint16_t DeviceAddr)
	Configure the FT6206 device to generate IT on given INT pin connected to MCU as EXTI. More...
void	ft6x06_TS_DisableIT (uint16_t DeviceAddr)
	Configure the FT6206 device to stop generating IT on the given INT pin connected to MCU as EXTI. More...
uint8_t	ft6x06_TS_ITStatus (uint16_t DeviceAddr)
	Get IT status from FT6206 interrupt status registers Should be called Following an EXTI coming to the MCU to know the detailed reason of the interrupt. More...
void	ft6x06_TS_ClearIT (uint16_t DeviceAddr)
	Clear IT status in FT6206 interrupt status clear registers Should be called Following an EXTI coming to the MCU. More...

Variables
TS_DrvTypeDef	ft6x06_ts_drv
uint8_t	ft6x06 [FT6x06_MAX_INSTANCE] = {0}
