Hi,


The latest Air Player BETA has better support for touch displays.
It uses a generic linux way to read the touch events. (it reads /dev/input/event0).

But is still depends from monitor to monitor. We have has success with a Dell s2240tb (works straight away) and Iiyama t2735msc (this one has a bug in the monitor itself that can be 'fixed' by setting the Pi ports to USB 1.1).

Hi Corjan,

I just intalled the Air Player V3.5 for Raspberry with a Waveshare 7-inch LCD(C) display. Display touch is working on standard Raspbian OS but not on Air Player (using same config.txt settings).

I checked the /dev/input/event0 using evtest and the touch information is coming but still no response from Air Player.

Does V3.5 reads /dev/input/event0 ?

Is there any test / change you would suggest me to do?

Thanks in advance,

Paulo

Hello,

I would like to report an additional test using a Waveshare 10.1 inch LCD(B) https://www.waveshare.com/wiki/10.1inch ... with_case)

Image is ok.

Touch and mouse not working with AirPlayer.

Testing same HW with another SD card with Raspbian, both touch and mouse are working perfectly (either connecting both or just connecting one of them).

Checking with evtest on AirPlayer SD card, I have following results:

1) only touch connected -> touch info at event0
2) only with mouse / keyboard connected -> keyboard at event0 and mouse at event1
3) both connected -> keyboard at event0, mouse at event1 and touch at event2

I hope those info can help on making mouse / touch working on Raspberry.

Hello Sim Innovations Team,

Since I did not get any feedback on RPI touch screen issue, I understand there is no solution for that. I bought Air Player Raspberry PI license to use with a touch screen monitor. Now this license has no use for me.

Are you able to revert may AP RPI license into a Air Player Desktop license?

Thanks in advance,

Paulo

The plan is to have it supported again in version 3.6, which releases somewhere before June.

Thanks Ralph for the fast answer.

In that case, I will wait for 3.6 because RPI is a much compact setup.

I am available for beta tests, if necessary.

Thanks,

Paulo
