Hi all,
I have a Waveshare 3.2 V3 LCD and a raspbeery pi 2 powered by raspbian.
The screen works well, but I am not able to get the touch working.
There is not any /dev/inputs/* device...no event*, no touchscreen file.

Any idea?
Thank you very much.
Regards.

Paolo

That guide is not working on my raspberry, I do not have the fbcp file

Code: Select all

update-rc.d: error: unable to read /etc/init.d/fbcp

I've got the Waveshare 3.5" so not 100% sure if same but I had to add

Code: Select all

dtparam=spi=on
dtparam=i2c_arm=on
gpu_mem=128
dtoverlay=ads7846,speed=500000,penirq=17,swapxy=1

to /boot/config.txt and then make a two files in /usr/share/X11/xorg.conf.d
99-calibration.conf and 99-fbturbo.conf

I've got my screen rotated vertically so don't want to confuse you with my files. xinput_calibrator helps a lot but unfortunately it wasn't in the Raspbian repos. Adafruit peeps got a package floating around the Interwebzes though.
