Functions

void ft3x67_Init (uint16_t DeviceAddr)
 Initialize the ft3x67 communication bus from MCU to FT3X67 : ie I2C channel initialization (if required).
void ft3x67_Reset (uint16_t DeviceAddr)
 Software Reset the ft3x67.
uint16_t ft3x67_ReadID (uint16_t DeviceAddr)
 Read the ft3x67 device ID, pre initialize I2C in case of need to be able to read the FT3X67 device ID, and verify this is a FT3X67.
void ft3x67_TS_Start (uint16_t DeviceAddr)
 Configures the touch Screen IC device to start detecting touches.
uint8_t ft3x67_TS_DetectTouch (uint16_t DeviceAddr)
 Return if there is touches detected or not.
void ft3x67_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 'ft3x67_handle.currActiveTouchIdx'.
void ft3x67_TS_EnableIT (uint16_t DeviceAddr)
 Configure the FT3X67 device to generate IT on given INT pin connected to MCU as EXTI.
void ft3x67_TS_DisableIT (uint16_t DeviceAddr)
 Configure the FT3X67 device to stop generating IT on the given INT pin connected to MCU as EXTI.
uint8_t ft3x67_TS_ITStatus (uint16_t DeviceAddr)
 Get IT status from FT3X67 interrupt status registers Should be called Following an EXTI coming to the MCU to know the detailed reason of the interrupt.
void ft3x67_TS_ClearIT (uint16_t DeviceAddr)
 Clear IT status in FT3X67 interrupt status clear registers Should be called Following an EXTI coming to the MCU.
void ft3x67_TS_GestureConfig (uint16_t DeviceAddr, uint32_t Activation)
 Configure gesture feature (enable/disable).
void ft3x67_TS_GetGestureID (uint16_t DeviceAddr, uint32_t *pGestureId)
 Get the last touch gesture identification (zoom, move up/down...).
void ft3x67_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 :

  • weight that was applied to this touch
  • sub-area of the touch in the touch panel
  • event of linked to the touch (press down, lift up, ...)

void TS_IO_Init (void)
 Initializes Touchscreen low level.
void TS_IO_Write (uint8_t Addr, uint8_t Reg, uint8_t Value)
 Writes a single data.
uint8_t TS_IO_Read (uint8_t Addr, uint8_t Reg)
 Reads a single data.
uint16_t TS_IO_ReadMultiple (uint8_t Addr, uint8_t Reg, uint8_t *Buffer, uint16_t Length)
 Reads multiple data with I2C communication channel from TouchScreen.
void TS_IO_Delay (uint32_t Delay)
 Delay function used in TouchScreen low level driver.
