9 years ago That is the instruction for resistive screen. Instead of running sudo adafruit-pitft-helper -t 28r Try sudo adafruit-pitft-helper -t 28c
As stated in the script help. https://github.com/adafruit/Adafruit-PiTFT-Helper/blob/master/adafruit-pitft-helper
Also, I would suggest you download the latest weezy and see if you can get the pitft working there in case the resistive pitft is causing issues on Octopi when trying to use the capacitive.
Good luck and let us know the result!

9 years ago If I run startx I can use the touch screen. Just not when Octopipanel screen is on

9 years ago Ok so it looks like the Touchscreen is working. I can hit he reboot.
But as soon as it is connected to the printer I get this error.
Please let me know if I should move this over to the OctopiPanel Github
pi@octopi ~ $ ~/scripts/OctoPiPanel sh: 1: cannot create /sys/class/gpio/gpio252/direction: Directory nonexistent sh: 1: cannot create /sys/class/gpio/gpio252/value: Directory nonexistent OctoPiPanel initiated

9 years ago Ok so I did an update via Git just to check I was on the dev and I was but after I did this. I am all operational. No maybe not the latest version was getting installed? So now running on Rpi b+ with a capacitive touch screen.

9 years ago Great! I emails in am answer asking you about the versions and branches but it seems not to have been added to the comment list.
Good that it works!
Can I get help setting up the Capacitive version of the PTtft. I tried using the script. But it doesn't work I am guessing it is for the resistive version only.
So I run the setup on the Adafruit page https://learn.adafruit.com/adafruit-2-8-pitft-capacitive-touch/easy-install
I can now get Page to display but I don't appear to have touchscreen. I runt the config and it tells me
pi@octopi ~ $ ~/scripts/calibrate-rpi-display xres = 320, yres = 240 selected device is not a touchscreen I understand Took 1 samples... Top left : X = -1225509860 Y = -1094484708 Took 1 samples...

Can anyone help. Thanks Matt
