Functions

static uint8_t ft5336_Get_I2C_InitializedStatus (void)
 Return the status of I2C was initialized or not.
static void ft5336_I2C_InitializeIfRequired (void)
 I2C initialize if needed.
static uint32_t ft5336_TS_Configure (uint16_t DeviceAddr)
 Basic static configuration of TouchScreen.
void ft5336_Init (uint16_t DeviceAddr)
 Initialize the ft5336 communication bus from MCU to FT5336 : ie I2C channel initialization (if required).
void ft5336_Reset (uint16_t DeviceAddr)
 Software Reset the ft5336.
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.
void ft5336_TS_Start (uint16_t DeviceAddr)
 Configures the touch Screen IC device to start detecting touches.
uint8_t ft5336_TS_DetectTouch (uint16_t DeviceAddr)
 Return if there is touches detected or not.
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'.
void ft5336_TS_EnableIT (uint16_t DeviceAddr)
 Configure the FT5336 device to generate IT on given INT pin connected to MCU as EXTI.
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.
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.
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.
void ft5336_TS_GetGestureID (uint16_t DeviceAddr, uint32_t *pGestureId)
 Get the last touch gesture identification (zoom, move up/down...).
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 :

  • 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, ...)
