1. How To use this driver: -------------------------- - This driver is used to drive the touch screen module of the STM32746G-Discovery board on the RK043FN48H-CT672B 480x272 LCD screen with capacitive touch screen. - The FT5336 component driver must be included in project files according to the touch screen driver present on this board. 2. Driver description: --------------------- + Initialization steps: o Initialize the TS module using the BSP_TS_Init() function. This function includes the MSP layer hardware resources initialization and the communication layer configuration to start the TS use. The LCD size properties (x and y) are passed as parameters. o If TS interrupt mode is desired, you must configure the TS interrupt mode by calling the function BSP_TS_ITConfig(). The TS interrupt mode is generated as an external interrupt whenever a touch is detected. The interrupt mode internally uses the IO functionalities driver driven by the IO expander, to configure the IT line. + Touch screen use o The touch screen state is captured whenever the function BSP_TS_GetState() is used. This function returns information about the last LCD touch occurred in the TS_StateTypeDef structure. o If TS interrupt mode is used, the function BSP_TS_ITGetStatus() is needed to get the interrupt status. To clear the IT pending bits, you should call the function BSP_TS_ITClear(). o The IT is handled using the corresponding external interrupt IRQ handler, the user IT callback treatment is implemented on the same external interrupt callback.
