Touchscreen issue

So i can’t get my touchscreen (something like slow scanlines) to work using following config:

 max_usb_current=1
 hdmi_group=2
 hdmi_mode=87
 hdmi_cvt 800 480 60 6 0 0 0
 hdmi_drive=1
 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=3900

Any more information about would be fine. Type of the screen etc.

hdmi_cvt 800 480 60 6 0 0 0

Is that a typo? It should be hdmi_cvt=…

    hdmi_cvt 800 480 60 6 0 0 0

Is that a typo? It should be hdmi_cvt=…

After i’ve fixed the typo the result is still the same

The config.txt I use on my Adafruit 5" touch screen is:

disable_overscan=1
hdmi_drive=2
fake_vsync_isr=1
gpu_mem=64
init_emmc_clock=100000000
hdmi_force_hotplug=1
hdmi_group=2
hdmi_mode=1
hdmi_mode=87
hdmi_cvt 800 480 60 6 0 0 0
max_usb_current=1
kernel=RISCOS.IMG
framebuffer_swap=0
ramfsfile=CMOS
ramfsaddr=0x508000

I’ve took some inspiration from this config like getting the display config at the beginning but it didn’t give me any positive results it still looks the same (see image on first post)

Have you been able to get it working on Debian?
Have tried connecting to a larger display using the 800 × 480 settings? (It may well not work but it is worth a try)

touchscreen Waveshare’s 5" Resistive 800×480 touchscreen

Looks comparable to my “eleduino 800×480 hdmi touch display”.

I use a normally config and a MDF based on the Generic.Pandora MDF.

1) Yes. It worked fine on debian
2) I have been using a VGA monitor but i currently don’t have access to it.

Would someone be able to summarise the status of touchscreen support please? This thread seems to start off with issues driving the monitor part, rather than the touch part, but references to touchscreens “working” imply that the touch part operates. Other responses suggest that touch can cause a Select, and presumable also move the pointer.
Are my assumptions correct? I have an application which operates entirely through the mouse and the select button, so should be able to use a touchscreen. I’d like confirmation before buying anything.

I can confirm that both the display and touch component work with the Adafruit touchscreen (based on the Microchip AR1100). I don’t know about others, but anything reporting itself as an “absolute” pointing device “should” work.

As I wrote here a touchscreen support (means with touch) for any devices is available. Feel free to send a feedback to Thomas.

Have made a “playground-bundle”. RPi4 + DSI screen + WiFi-Hat + ROdirect-Image… Have add the touchscreen driver, my YTPlay and a smaller version of Kevins VKeyboard…

All is working fine together. Play the youtube video and have scale it down (is slower on Pi3)…
