I currently have this screen: https://www.waveshare.com/wiki/5inch_HDMI_LCD
And the visual part works fine, but I'm having a bit trouble with the touch part. I don't get it to work.
I have the following in my config.txt
dtparam=i2c_arm=on dtparam=i2s=on dtparam=spi=on dtparam=i2c=on enable_uart=1 hdmi_group=2 hdmi_mode=1 hdmi_mode=87 hdmi_cvt 800 480 60 6 0 0 0 dtoverlay=ads7846,cs=1,penirq=25,penirq_pull=2,speed=50000,keep_vref_on=0,swapxy=0,pmax=255,xohms=150,xmin=200,xmax=3900,ymin=200,ymax=39
But no touch. I have confirmed that I have the "ads7846-overlay.dtb" file in the overlays folder so that should be ok.
I also have the /dev/input/touchscreen0 device and when I 'cat' that file and touch the screen I do get output so it must be registering something. The wiki from my screen lists that you can calibrate it but I cannot install the package as dpkg is not present.
Any tips here? Would be great to get the touch working so I could switch from the menu to the overview :)
