When I run ts_calibrate the display flashes with the crosshair screen for a very very brief time and on the terminal it export export ts_calibrate IвЂ™ve successfully enabled the SPI display output and rotated the screen to my liking, thanks to your instructions and kudos for the same.ДЇirst, my touchscreen wont recognise touch.

I am also using the same waveshare 3.2вЂі touchscreen as you are and I followed all the instructions clearly. The touchscreen is working good thats not the problem. Selected device is not a touchscreen I understand I am an absolutly noob i have no idea whats export export ts_calibrate I use the Waveshare 3.2 v4 on my RPi2 display and by the calibration with putty i have the same problem no touchscreen monitor i understand. Enter sudo su at the command prompt to enter root mode: This process needs to be done using super user (root) privileges.

This will make the pointer much more accurate and easier to use.ДЎ. Now that we have our LCD touchscreen up and running, the final step in the installation is the calibration of touch control. Here is a short video tutorial showing the steps above: All you need to do is switch the values of the 0 and 1 at the end of this line. Then change the DISPLAY=:0 xinput -set-prop 'ADS7846 Touchscreen' 'Evdev Axis Inversion' 0 1 line in theВ /etc/X11/xinit/xinitrc file to DISPLAY=:0 xinput -set-prop 'ADS7846 Touchscreen' 'Evdev Axis Inversion' 1 0. To do this, simply enter fbtft_device.rotate=270 in theВ /boot/cmdline.txt file. You can rotate the screen 90 degrees (as we did in this tutorial) and the power connector will be at the bottom of the screen, but you can also rotate it 270 degrees so that the power connector is at the top of the screen. Change Screen Rotation to Any Orientation If you are using the Raspberry Pi 2 Model B, you will need to complete the calibration steps below before the pointer follows your finger correctly (and make sure that you have enabled startx to load automatically вЂ“ see step 6 in this article).

Press Ctrl-X then Y to exit nano and save the changes, then enter sudo reboot to reboot the Pi.ДЄfter the Pi finishes rebooting, you should notice that when you move your finger across the touch screen, the pointer should follow correctly in both axes.
