Jerome Coutant 0:146cf26a9bbb 22 User NOTES
Jerome Coutant 0:146cf26a9bbb 23 1. How To use this driver:
Jerome Coutant 0:146cf26a9bbb 24 --------------------------
Jerome Coutant 0:146cf26a9bbb 25 - This driver is used to drive the touch screen module of the STM32H747I_DISCOVERY
Jerome Coutant 0:146cf26a9bbb 26 discovery board on the K.O.D Optica Technology 480x800 TFT-LCD mounted on
Jerome Coutant 0:146cf26a9bbb 27 MB1166 daughter board. The touch screen driver IC inside the K.O.D module KM-040TMP-02
Jerome Coutant 0:146cf26a9bbb 28 is a FT6206 by Focal Tech.
Jerome Coutant 0:146cf26a9bbb 29
Jerome Coutant 0:146cf26a9bbb 30 2. Driver description:
Jerome Coutant 0:146cf26a9bbb 31 ---------------------
Jerome Coutant 0:146cf26a9bbb 32 + Initialization steps:
Jerome Coutant 0:146cf26a9bbb 33 o Initialize the TS module using the BSP_TS_Init() function. This
Jerome Coutant 0:146cf26a9bbb 34 function includes the MSP layer hardware resources initialization and the
Jerome Coutant 0:146cf26a9bbb 35 communication layer configuration to start the TS use. The LCD size properties
Jerome Coutant 0:146cf26a9bbb 36 (x and y) are passed as parameters.
Jerome Coutant 0:146cf26a9bbb 37 o If TS interrupt mode is desired, you must configure the TS interrupt mode
Jerome Coutant 0:146cf26a9bbb 38 by calling the function BSP_TS_ITConfig(). The TS interrupt mode is generated
Jerome Coutant 0:146cf26a9bbb 39 as an external interrupt whenever a touch is detected.
Jerome Coutant 0:146cf26a9bbb 40 The interrupt mode internally uses the IO functionalities driver driven by
Jerome Coutant 0:146cf26a9bbb 41 the IO expander, to configure the IT line.
Jerome Coutant 0:146cf26a9bbb 42
Jerome Coutant 0:146cf26a9bbb 43 + Touch screen use
Jerome Coutant 0:146cf26a9bbb 44 o The touch screen state is captured whenever the function BSP_TS_GetState() is
Jerome Coutant 0:146cf26a9bbb 45 used. This function returns information about the last LCD touch occurred
Jerome Coutant 0:146cf26a9bbb 46 in the TS_StateTypeDef structure.
Jerome Coutant 0:146cf26a9bbb 47 o The IT is handled using the corresponding external interrupt IRQ handler,
Jerome Coutant 0:146cf26a9bbb 48 the user IT callback treatment is implemented on the same external interrupt
Jerome Coutant 0:146cf26a9bbb 49 callback.
