Cerbo GX enable touch for larger screen

Hi,

Is it possible to make the Cerbo GX accept a different touchscreen and get the touch functionality working. I have chosen a brand of touchscreen that should be supported by most Rpi versions out of the box, but touch still doesnt work with the Cerbo.

Any tips are welcome.

As far as I'm aware the GX Touch uses I2C data on the HDMI feed for the touch input which is non-standard. The USB is just for power.

So long story short, is no, it wouldn't be possible.

I can't stress enough that this feature should be on the top of the list. Having a single very responsive screen SUCKS. I so badly want a screen for the front of my RV but have to settle for a browser. I still think that Victron needs to think about scaling here. I should be able to buy another Cerbo GX and Touch and use the Cerbo as a Master/Slave relationship where the Slave mirrors the Master and extends sensors, ports, etc. Scaling seems to be Victron's biggest hurdle right now. OR if scaling is a major hurdle then provide a pub/sub REST service that allows customers to build their own UI.

Just a thought: Can you control the GUI on Cerbo with a USB mouse? If so, you should be able to add the USB touchscreen stuff that's used for Venus on the Raspberry PIs.

I have the same issue. I spent over $5,000 on Victron products, but my eyes are old and can't easily see the 5" monitor. I purchased a generic touch screen (large so I can see). The image is fine, but the touch is not working. I can attach a mouse, which works, but not the touch screen part. What's the deal, where is the support? I will pay for a download patch, just please fix this problem.

Hi

Yes you can use the raspi with there 7inch touch screen just connect thew the wifi access port, I use the kiosk mode to do this, as the raspi has wifi and bluetooth. so only needs power.

So it can be remote mounted etc.

You can pinch zoom etc.

I have a 7" HDMI touchscreen that works with Cerbo. It uses USB touch like most do. It was plug and play. No tweaks.

Make sure you aren't using the USB port closest to the HDMI connector. That one is power only.

Victron also now sells the GX Touch 70, a 7" version of the same excellent 5" touchscreen. I switched to that a while back.

Hi Kevin

So what was the model of HDMI you used? as a matter of interest? I use the raspi touch screen and CPU to do remote monitering via its WiFi link.

Also i am about to use yor Vecan setup to get the the USBcan working again on the raspi, i see they have gone back to zeus from dunfell in the candiate ver in the packages.

I have also the relay x6 on the front setting page working again, after the venus update etc.?

It is this one made by Waveshare:

I also used the "official 7" Raspberry PI touchscreen"

Hi.

I had the same issue with my new 7" touch screen 1024x600 IPS and the cerbo GX. Nothing looks normal and the touch function doesn't work.

When I turn Off the Cerbo GX, connected the HDMI to the Screen and the USB cable for the touch on the second USB port on the cerbo GX.

When I power ON the Cerbo GX, and now the touch screen works perfectly. Very simple and easy.

Hope this work for you.
