Gesture of CTP with FT5426 not working

Hi everybody,
i have problems with my FT5426 CTP Controller. I get the actuel coordinates via I2C from register 0x03 - 0x06 (TOUCH1_XH to TOUCH1_YL), this works fine.
But i have problmes with the gesture register. It only gives 0x00 (NO GESTURE) if i move up or down, left or right. I need this function but it doesn't work. Are there any more configurations i have to take? The device mode register shows WORKING MODE.

Thanks for your help.

  Hi Raphael,
  
  Please let us know the TFT size or part number of the display experiencing this issue.
  Also check the label on the touchscreen's FPC cable and report back the numbers printed on it.
  
  Here is a link to the FT5426 controller's application notes for your reference: https://www.newhavendisplay.com/resources_dataFiles/datasheets/touchpanel/FT5426_5526Application_Note_Ver0.1.pdf

  Hi Ted,
  
  thanks for your answer. I know the FT5426 application note. The reading of the x and y pixel postion is working. I only have problems with the gesture.
  The TFT size is 5" 800x480 pixel. The label on the touchscreen FPC cable shows FPC-CTP-0500-015-2.
  
  Thanks and Regards

  Hi,
  i have the same problem as the guy of the post with my NHD-3.5-320240MF-ATXL#-CTP-1 display.
  Coordinates via i2c works fine, but i have problems with gesture.
  Is there a register through i can enable and disable them? and if it exist what number is?
  Thanks for your help

  Hi ,
  
  The Gesture ID register can be found in section 3.3 in the Focaltech application notes:
  https://www.newhavendisplay.com/resources_dataFiles/datasheets/touchpanel/FT5426_5526Application_Note_Ver0.1.pdf
  
  Here is the link to the Focaltech touchscreen controller datasheet: https://www.newhavendisplay.com/resources_dataFiles/datasheets/touchpanel/FT5x26.pdf
  
  Linux drivers for the Focaltech controller can be found on our GitHub site https://github.com/NewhavenDisplay/FT5X26-Focaltech-Drivers/tree/master/FT5426_Linux_Driver

  Dear All,
  
  I am Gururaj here.
  I am trying to interface CTP FT5426 with the MSP430 microcontroller.
  I am using the NHD-7.0-800480EF-ATXL#-CTP display.
  Could anyone help me to make it work? I could able to read the interrupt from the FT5426 but not able to read any memory.
  
  Thanks
