| bcostm | 0:0002c86c2220 | 40 | User NOTES |
| bcostm | 0:0002c86c2220 | 41 | 1. How To use this driver: |
| bcostm | 0:0002c86c2220 | 42 | -------------------------- |
| bcostm | 0:0002c86c2220 | 43 | - This driver is used to drive the touch screen module of the STM32469I-Discovery |
| bcostm | 0:0002c86c2220 | 44 | board on the K.O.D Optica Technology 480x800 TFT-LCD mounted on |
| bcostm | 0:0002c86c2220 | 45 | MB1189 board. The touch screen driver IC inside the K.O.D module KM-040TMP-02 |
| bcostm | 0:0002c86c2220 | 46 | is a FT6206 by Focal Tech. |
| bcostm | 0:0002c86c2220 | 47 | |
| bcostm | 0:0002c86c2220 | 48 | 2. Driver description: |
| bcostm | 0:0002c86c2220 | 49 | --------------------- |
| bcostm | 0:0002c86c2220 | 50 | + Initialization steps: |
| bcostm | 0:0002c86c2220 | 51 | o Initialize the TS module using the BSP_TS_Init() function. This |
| bcostm | 0:0002c86c2220 | 52 | function includes the MSP layer hardware resources initialization and the |
| bcostm | 0:0002c86c2220 | 53 | communication layer configuration to start the TS use. The LCD size properties |
| bcostm | 0:0002c86c2220 | 54 | (x and y) are passed as parameters. |
| bcostm | 0:0002c86c2220 | 55 | o If TS interrupt mode is desired, you must configure the TS interrupt mode |
| bcostm | 0:0002c86c2220 | 56 | by calling the function BSP_TS_ITConfig(). The TS interrupt mode is generated |
| bcostm | 0:0002c86c2220 | 57 | as an external interrupt whenever a touch is detected. |
| bcostm | 0:0002c86c2220 | 58 | The interrupt mode internally uses the IO functionalities driver driven by |
| bcostm | 0:0002c86c2220 | 59 | the IO expander, to configure the IT line. |
| bcostm | 0:0002c86c2220 | 60 | |
| bcostm | 0:0002c86c2220 | 61 | + Touch screen use |
| bcostm | 0:0002c86c2220 | 62 | o The touch screen state is captured whenever the function BSP_TS_GetState() is |
| bcostm | 0:0002c86c2220 | 63 | used. This function returns information about the last LCD touch occurred |
| bcostm | 0:0002c86c2220 | 64 | in the TS_StateTypeDef structure. |
| bcostm | 0:0002c86c2220 | 65 | o If TS interrupt mode is used, the function BSP_TS_ITGetStatus() is needed to get |
| bcostm | 0:0002c86c2220 | 66 | the interrupt status. To clear the IT pending bits, you should call the |
| bcostm | 0:0002c86c2220 | 67 | function BSP_TS_ITClear(). |
| bcostm | 0:0002c86c2220 | 68 | o The IT is handled using the corresponding external interrupt IRQ handler, |
| bcostm | 0:0002c86c2220 | 69 | the user IT callback treatment is implemented on the same external interrupt |
| bcostm | 0:0002c86c2220 | 70 | callback. |
