I am using STMPE811QTR in my project for touch screen detection, schematic is similar to STM32F429 discovery board (display size 800 x 480)
STMPE811QTR is interfaced with STM32F429 on I2C bus, During the normal operation (if we touch the screen------interrupt generated--------master reads the co-ordinate on I2C------get proper value-----working OK)
but, sometimes
touch screen controller randomly generates the fake interrupt on INT (pin no. 2) i.e. interrupt generated without even touching the touch screen
due to which master controller reads the DATA on I2C line & get fake co-ordinates due to fake interrupt (as once master gets the co-ordinates, it displays the same on TFT)
due to such a erratic behavior of touch screen controller, user unable to use the device properly
kindly guide on the same
