Hi,
working on a new product, 7" HDMI display with optical touch should be used.
LCD works fine ( 1024x600).
But I'm hanging with touch.
Installed is: Linux beaglebone 4.19.94-ti-r64 #1buster SMP PREEMPT Fri May 21 23:57:28 UTC 2021 armv7l GNU/Linux
Plan is to write directly into the framebuffer, no X no desktop.
That works also fine, very fast.
But with touch .... I'm running out of ideas.
Was expecting a conflict with USB Network, is now deactivated, no change.
/dev/input/event0 is existing. But no events .
Touch hardware is ok, works fine on WIN10 PC.
I'm sure, I'm not the first one ..... need help on that.
Thanks in advance for every good hint :-)
Kasimir

PS I checked it with destop, also. Touch doesn't work.

Could you be having a conflict with the native LCD system (which is
active in parallel with the HDMI). The native LCD system expects a
capacitive touchscreen on the P9 (I think) pins.

Might help if you identified WHICH product you are using. This one
https://www.amazon.com/GeeekPi-1024x600-Capacitive-Monitor-Raspberry/dp/B075QCXLPF/ref=asc_df_B075QCXLPF/?tag=hyprod-20&linkCode=df0&hvadid=309707619534&hvpos=&hvnetw=g&hvrand=5324710204179150785&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9017241&hvtargid=pla-570706414713&psc=1
mentions a "free driver" (I would hope so -- I doubt they'd sell many if
they said the driver was extra cost; though the best documentation I find
for it says "driver-free" -- meaning no driver needed).

I would note that the compatibility list on
<https://wiki.52pi.com/index.php/7-Inch-1024x600_Capacitive_Touch_Screen_(Extend_Two_USB_HOST_Port)_SKU:_EP-0085>
does NOT mention beagle bone, though the body text does.

"""
Power Supply 5V/1A via USB port
"""
OUCH! Beagle USB maxes out at 500mA (which is the spec for USB2); you'll
need a powered USB hub with high-power ports.

"""
Please make sure the FPC cable is fastened and please connect the
MicroUSB cable to your device so that it can communicate with the touch
panel.
Please make sure the USB power cable is connected properly.
"""

Implies one needs to use a separate USB power supply

One port is power, the other is data.

Hi Dennis,
yes, the board looks similar. Of course I powered with a separate power supply :-)
That's my board:
Works fine on Windows PC, so it's not defective.
I like it, brilliant colors, wide angle .... but Beaglebone Black is ignoring the touch.
I'm using the current IOT Debian buster image.

The project requires the pru units, that works fine.
Touch is eating up my time. And I expect it makes no sense to order other touch displays and the status is still the same.
USB based touch was expected as "best and simple" solution. I need SPI and GPIO for surrounding hardware. That works fine.
HDMI is required to have the possibility to connect "any" monitor. There is 1m distance between BBB and display.
RPI is not an option for me, because I need the PRU's.

Thanks for help

Hi Robert,
I found it. Need to calibrate now.
More later

Hi Robert,
it's solved. Hardware, the USB connector. 
Was able to solder, now it works fine.
Sometimes there was a second entry with lsusb. Then I found out, it's the connector, with a little pressure it worked.
Then microscope, solder iron....
I spent 2 days and nights on that 😭
But I learned a Lot
Thanks to all
Kasimir

So it was the display USB that had the issue.  Not the BBB.

How do you like the touch response on that display?

It was the Beaglebone USB connector.
Touch is currently not calibrated.
But on my WIN10 PC it works fine. Can recommend the display.

The reason I ask is based on the information here:

https://elinux.org/Beagleboard:BeagleBoneBlack_HDMI

 

In the past I've had the most success using an external HDMI to VGA connector that then feeds into a Viewsonic LED 1080P Full HD monitor.  VX2753MH-LED.  This one doesn't really like 1920x1080@30 so the Beagle has trouble talking to it.

https://www.viewsonic.com/nz/products/lcd/vx2753mh-led

 

 

Do these smaller displays present as 30Hz?  Seems given the capabilities of the BBB it might be better to target a small 7" to 10" LCD display in the 1280x768 size.  I know I had a lot of trouble with the Mango screens for the Replicape project with the higher resolution.   Touch on the Manga1 was crap.  Support for the entire project kind of vanished and now it turns out one of the stepper drivers is toast.  Never really got far with the Manga2 after all that

 

But the point is the higher res screens on a small physical footprint don't do much so I was curious about this display and how well the touch actually worked.

 

John

The touch response  on my am335x SK works well. SD card comes with a touch GUI. Schematics and BOM

Hi John,
the LCD Display is good. Think my defektive Beaglebone USB connector is also the reason for undeted WIFI .... will try again.
