Which screen type can I connect to the Raspberry ?

#1 Post by PapaLima » Fri Jan 05, 2018 11:05 am

Hi all,

I am a new user of the AirPlayer for Raspberry. Actually I succeed to connect a common flat screen (PC desktop type) using the Pi2 HDMI port output. I see my gauge(s) it is ok.

I am wondering if we can connect a dedicated Pi LCD flat screen (2.8" or 3.5" for example) to display any gauge without having to use a connected desktop screen.
It could be a more compact solution to place an external gauge somewhere in the cabin.

Thanks
Bye

It's probably possible, but you will have to do some manual configuration to get the panel working. Which is probably described at the webpage of the manufacturer.

Hi

There are some standard 3.5", 5", 6", 7" and 10.1" HDMI screen made for the Raspberry that should work.
https://www.amazon.fr/10-1inch-HDMI-LCD ... B01CU7VX5Q

The only question is about the max resolution of these screen, ranging from 480x320 up to 1024x600 for the max.

Will Air Player be handling such a low resolution?

Thanks. Good to know.

One thing I remarked during my searches is that such TFT screens are using the GPIO slot... thus we have no possibility to have access to the unused GPIO pins to add switches or LEDs...

Yes it will be best to use a "normal" HDMI small screen. Thanks for the link

can the touch function of this type of screen be used. If true what procedure do I need to do to activate it? I have tried LCD.show, enabled SPI and installed libinput this failed to enable touch. Or do I have to use this type with direct serial input

If not used with a Raspberry, Touch input should be enabled in Settings tab, or per panel in the Panels tab, starting with the last versions os AM 3.5 Beta (at least Beta 30 and up if i remember well)

I can't say for Raspberry, if the touch input is, or not, forwarded on another bus type than USB
i only remember having already used a 7 inch touch screen, with an onboard direct link through a flat orange flexible cable (native touch logic without specific activation need)
and the video through HDMI

so, not sure it would work in AM the expected way

Whilst I see this a a topic. I have been trying for nearly one year to get the touch screen on my 10.1 to work.

It issue is that the touch screen driver needs to be installed on the SD card. There is no way that I know how to add the driver to the AM image.

This is the screen I have.

EDIT:

If I install the driver on a a rasbian/ubantu image the touch screen works perfectly.

Keith,

I feel your pain. I have also had no luck with a usb touch screen that’s plug n play on windows.

I think it’s something that needs addressing, after all one of the big benefits of AM is the touch support. It’s just the Rpi touch support that’s problematic.

Good to have you back.

Tony

Thank you Tony.
I will slowly try and work my way back. I see a lot has been done during my absence.
