| static uint32_t | ft3x67_TS_Configure (uint16_t DeviceAddr) |
| Basic static configuration of TouchScreen. | |
| 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. | |
