DIY WiFi Raspberry Pi Touchscreen Camera does not respond wh

Hello,

I assembled the
Raspberry Pi 3 Model V1.2
Adafruit 2.8" 320x240 TFT w/Touchsreen (capacitive) Pi TFT model B+/Pi2 (some numbers on the back : ILI9341 STMPE610 or FT6206) found on https://www.adafruit.com/product/2423
and a pi noir camera V2.1

I followed the steps in Adafruit 2.8" PiTFT - Capacitive Touch https://learn.adafruit.com/adafruit-2-8 ... sy-install and installed the image https://s3.amazonaws.com/adafruit-raspb ... ft-28c.zip and followed the configuration instructions and that worked fine. The pi boots to the graphical interface and i could click around using the touch screen. Although the screen is to small to be practical i had the impression it work as should be.

Then i followed the steps in DIY WiFi Raspberry Pi Touchscreen Camera https://learn.adafruit.com/diy-wifi-ras ... m/pi-setup That seems to go fine, i can run the camera program with sudo python cam.py and the display shows the camera feed with settings and next button. But when i touch the screen (no matter where on the screen) the program hangs for several minutes and just shows slow camera updates alternating with the adafruit logo and Working... (see picture)

After a few minutes i go back to the normal camera screen with faster camera update and settings and next button.

I am having the same problem with the resistive touch screen. No matter where I touch the screen the camera takes multiple pictures over a period of several minutes. Touching the gear or the arrow icon also takes pictures. I down loaded the software again and reinstalled it. I also changed touch screens (both were purchased about 2 weeks ago). It still doesn't work. Any thoughts of where to trouble shoot would be appreciated. Joe

I was told the problem can be solved by enabling I2C. In the default config of adafruit I2C is not enabled. Every time you touch the screen the (x,y) coordinates return (0,0). Enabling I2C should solve this issue.
