Hi I have performed all the steps and I have made the display work but the touch is not calibrated well.
In particular, when I click on a point on the right it is as if I click on the left, while up and down they work.
I use this configuration:
Option “Calibration” “3936 268 227 3880”
Option “SwapAxes” “0”
Rotate=270
Thanks to those who want to help me configure the touch better
Hi Thanks for all the help here. With some pain I got my TFT working as well.
The main points to get the tft running for me was:
I used the shell script (written by Darmur on May6, see earlier in the thread) to create the changes to reproduce the config easily.
my 5 inch waveshare touchscreen touch not working also display fills 2/3 rd screen only
Please give some more details:
What is the exact model name of the display?
Did you install other software / modify files in order to use the display? If so, please describe in detail what you installed or modified.
Open the file “/boot/userconfig.txt”:
sudo nano /boot/userconfig.txt
Add the following lines:
dtparam=spi=on
hdmi_drive=1
hdmi_group=2
hdmi_mode=87
hdmi_cvt 800 480 60 6 0 0 0
dtoverlay=ads7846
dtparam=cs=1
dtparam=penirq=25
dtparam=penirq_pull=2
dtparam=speed=50000
dtparam=swapxy=0
dtparam=pmax=255
dtparam=xohms=150
dtparam=xmin=200
dtparam=xmax=3900
dtparam=ymin=200
dtparam=ymax=3900
To close nano and save “/boot/userconfig.txt” type Ctrl+x, y and Enter.
Reboot.
thanks the display is working
the touch not working though
Please post the results of
cat /boot/config.txt
and
cat /boot/userconfig.txt
“/boot/config.txt” and “/boot/userconfig.txt” look ok. In “/boot/userconfig.txt” there should be a line break after dtparam=ymax=3900. Although I don’t expect this to be causing the problem please try adding the mentioned line break to be on the safe side.
Apart from that the triple repetition of the last entries in both files appears strange to me. Do you have an idea what could have caused this?
To investigate further please post the results of
ls -al /dev/input
ls -al /usr/share/X11/xorg.conf.d
and
ls -al /etc/X11/xorg.conf.d
P.S. If possible don’t post images of the output of such commands but try to copy and paste the output as plain text and format it with code tags here. It’s easier read on mobile devices and can be searched through, too.
ls -al /dev/input

Looks normal.
Please execute
cat /dev/input/event*
and touch the screen. Do you see cryptic signs then in the terminal window?
You can exit the running “cat” command with Ctrl+c.
nothing happens
Hm, according to this in a thread that covers the same screen as yours nothing more should need to be adjusted than “/boot/userconfig.txt”.
BTW did you add the line break in “/boot/userconfig.txt” I mentioned above and reboot? If not, try that first. If touch still should not work maybe you need to install xserver-xorg-input-evdev
sudo apt-get install xserver-xorg-input-evdev
After that execute
sudo cp /usr/share/X11/xorg.conf.d/10-evdev.conf /usr/share/X11/xorg.conf.d/45-evdev.conf
and reboot.
gvolt, thanks. Touch is working fine now. My son is enjoying Volumio in his toolshed
Ben
