NHD-3.5-320240MF-ASXV#-CTP Increase touch sensitivity
« on: December 03, 2018, 08:27:23 AM »
Hi,

We have purchased NHD-3.5-320240MF-ASXV#-CTP displays to our product where we need to use 2mm protective glass on front of display
The problem is I can't change sensitivity in FT-5x16 touch controller used in this version (0318)
It worked with FTx06 in older versions of display

Write to Address 80h and 81h worked fine in FTx06 but in FTx16 there is no change in sensitivity
Am I missing something?

Thanks in advance for any help

Pekka

Hi pekka.k,

The default values for the FT-5x16 controller are different than the FT5x06 so the value range will be different.
Please refer to the FT5x16 controller register data for more details: http://www.newhavendisplay.com/appnotes/datasheets/touchpanel/FT5x16_registers.pdf
Let us know what values were working to get the proper sensitivity on the FT5x06 and the new value range you have tried.

Best Regards,
