Peter,

Updated the PicoMite MMBasic RP2040 V6.03.00RC15 test firmware and copying the long file from A to B with FM first marked with * and then F5 works perfectly now. Thanks.

Jan.

Has anyone been able to get USB touch working that connects to the Pico via HDMI (for the video) but with a screen that also accepts video via the same USB C that touch is on??

Peter - with your thorough knowledge, is the above a non starter for screens that use the USB for video and touch? I.e. does the usb need to be dedicated to touch data only?

Has anyone seen this before?
I have no video signal. Perhaps the OPTION VGA PINS aren't working correctly?
I also no longer see the option resolution 640x480 @ 252000 KHz.
It did work with an older version. Or is there something wrong with my hardware?

Peter,

Thanks for investigating and the response.

I am going to investigate further why it works correctly with PicoMiteVGA MMBasic USB RP2040 Edition V6.03.00RC9 but not with V6.03.00RC15, and how it is with the intermediate versions.
If I find anything, I will let you know.

Jan.

Hi Peter,
is there any update on the multi-touch issue with the MageDok display?
Is there anything I can do to help?

Does that report include definitely trying two fingers at the same time? If not please run again with the version that had the diagnostics and specifically try touching in two places at once. This is needed to see if the required report is actually happening. That controller boots up in "mouse" mode. i.e. single touch and simple reports but I need to know if the multi-touch reports are also happening.

Peter,

I reloaded PicoMiteVGA MMBasic USB RP2040 Edition V6.03.00RC15 and performed OPTION RESET.
Also > Drive "A:/FORMAT" and then copied options line by line from Notepad++ to Tera Term in a specific order.
After that, I transferred the backup folder using FM. I made some adjustments to the options list.
PiZero module with a 64x29mm perforated board underneath containing RTC+EEPROM, VGA connector and resistors, and an I2S module with 3mm spacer sockets.
All pins are accessible and the unused HDMI pins have been used for VGA. The whole assembly is 35mm high and compact. A speaker set from Action (12 Euros) makes it complete. The bottom was finished with a similar perforated board.
On the PiZero, I adjusted the debug pins for Rx=GP9 and Tx=GP8.
Everything is working properly so far.

Thanks for the support.
This is my options list:

Another question. Have you run the display on a windows machine. Can you confirm if multi-touch works on any other host?

Hi Peter,

I've cheekily taken the opportunity to attach a 'HID report descriptor' file for an OLED screen. This is with the hope that you can help get the USB multi-touch to work on it.

Touch HID report descriptor.zip

As you'd requested in earlier posts for some other screens, I'm hoping there's enough info in there, but if needed, I can run any other tests required.

Thanks for any help you can provide.....

EDIT: I can confirm it works 100% when connected to a Win 11 laptop (via HDMI for image, and via a single USB for touch & power

Yes, win11 oout of the box, multitouch and gesture control also works with two-finger zooming!

The old Records also mentioned 3-finger touch.
I was out and about. Tomorrow I’ll finish up several test runs with descriptions and upload them here for you.

@Peter,

minor issue: the BACKLIGHT command in the HDMI version is still not an "no-op" command as announced but throws an error (Error : unknown command)

Peter,

At first I was put off by WhiteWizzard’s report, but I gave it a go anyway.
The result is that initially there’s no debug output either, and the “gui test touch” command clears the screen but doesn’t respond to it.

However, I noticed that after a reset and a quick, immediate "gui test touch", there is a brief window during which the screen responds to the test. After that, though, it stops responding. Only a RESET causes the behaviour to reappear, so it is reproducible.

Attached is an image showing single-touch and two-finger-touch.

Matthias

Update: I can even reconnect the Microsoft mouse/keyboard dongle without a Hex Debug message appearing. However, the behaviour remains the same. The pump demo works via touch for a brief moment, then there is no response again. After that, it only works with the mouse.

I'm unclear what you are reporting. Is multi-touch now working but stops after a period? Does single touch also now stop when it didn't before?

This version should have the debug

3. gui test touch <--- immediate entry
4. You have about 5 seconds to test the touch, whether single or multi-touch! After that, only the touch function stops working. The Pico can still be fully operated via the terminal.
5. goto 1

With the RC15, the touch operates in single-mode throughout!
