	Return status and positions of the touch screen.
uint8_t	BSP_TS_GestureConfig (FunctionalState State)
	Configure gesture feature.
uint8_t	BSP_TS_Get_GestureId (TS_StateTypeDef *TS_State)
	Update gesture Id following a touch detected.
uint8_t	BSP_TS_ResetTouchData (TS_StateTypeDef *TS_State)
	Reset all touch data before a new acquisition of touch information.
uint8_t	BSP_TS_ITConfig (void)
	Configure and enable the touch screen interrupts.
uint8_t	BSP_TS_ITDisable (void)
	Deconfigure and disable the touch screen interrupts.
void	BSP_TS_ITClear (void)
