Firmware contains also sensitivity setting, or it must be do separately?
have you seme desryption for calibrate FT5336?. I cannot find any information.

In attachment i give some screen where I still have finger on the screen
1. overview
2. first read (0ms)- put down, so ok...
3. after several frame (50ms)- one finger and contact, so ok.
4. next frame aster 3.png- put down again (bad)
5. some frame. No finger and put up the finger

This bad frame is many in each touch sesion. I show only several for example.

FT5336 is from FocalTech, not from FTDI

Hello Saurabh, this display is not from NHD- you don't have this type what we need.
In this case I can get also a bit help from your side? :(

I have also FT test board and change firmware- without change, CTP still is sick. But I think that when it is connected to this test board, then CTP work better. (some supply issue?).

I look and compare I2C transmission- all is ok and the same. I have no idea ;/

Ferrite and resistor you must place close as possible to clock (emission) source. In this case I think that your I/O port in microcontroller.

TFTs / FT5336 problem with sensitivity and gesture
« on: October 16, 2017, 04:47:53 PM »
At first... hello all. I try to run display with this CTP but pdf are poor...
Now, small problem. Gesture register still give back 0, no matter what I draw by finger. It's normally?
And here is my big problem. I have three display, one work ok, but other two rages when I only touch it. FT cannot decide that I touch it by one or more finger, similar is with XY position. Is possible to adjust senstivity or change treshold point?

I find also pdf for FT5306 where I see register 0xA6h (firmware). In good module I see here 7, in bad is 6. But I'm not sure that is good way to read this register who I don't see in screen pdf (where is not write directly but is on FT5336)
