Touch Screen Interface

I bought a 19" ZB190TC-591R (https://nl.aliexpress.com/item/32819856199.html). And it works. Out-of-the-box the calibration of the resistive touch screen was off. Not by much, but in the lower-left corner it was hard to hit the shift and 'num' key, for example.

iChawk offers Windows (Mac, Linux, ...) drivers that can be used to calibrate the display. And the calibration constants are stored in the screen. http://www.ichawk.com/en/download.php?page=1 offers downloads, for modern Windows installations "3-iChawk Resistive Touch Screen Driver (Windows 7-8-10 32-bit & 64-bit)" works.

The software is ugly, but works. After installation one has a eGalaxTouch program on one's desktop. And that allows for a 4- or 9-point calibration that fixes the issue also for the MASSO controller.

Thank you for sharing that.

Me again. I found this Deltaco 12.1" 4 wire resistive thing close to me, at a bargain price. It even has the correct resolution. Right out of the box the image is fine and covers the whole screen, it does respond to some touching, but it seems totally random. I can change between F1 and F2 screens by pressing somewhere on the left vertical part of the screen,and that is just about it.
It came with a CD (!!) of which I have no means to run, and fiddling around in the manual and menu doesn't seem to change much.
Does anyone have an idea what I can do to calibrate this monitor? Can it be that that's what the included CD is for?

A little update:
I tested the touch screen on an old PC with Windows 7. The same thing happened there (inverted or random touch, hard to tell).But this PC had a CD drive, so I inserted the CD that came with the screen, and found it had loads of drivers to suit different operating systems.
Installed the one for Windows 7, and voila, it works on that specific PC.
Obviously, it didn't do anything to the touch screen firmware, because when I plugged it back into Masso, it was the same story as before.

Could this provide hope that I can use one of these drivers for Masso? If so, can someone at Masso support guide me towards updating the driver on the Masso to suit my screen? I took a picture of the list of drivers and attached it.

MASSO is not PC and you cannot load touch screen drivers. If it does not work when plugged into MASSO it is not compatible.

When it's on the W7 machine adjust it as needed for the Masso screen, power it down then try it on the Masso.. Others have reported this working on the forum..

Thank you for your response! I am having a hard time figuring out if, and then how, my settings can be stored in the screen. That would be nice. There is some setup possibilities in windows, and there are some in the installed "wizard" that came with the CD. But I can't see that it stores in the screen in any way, as I am just back to scratch when connecting it to Masso again.

That depends on how the monitor stores it data, I would go so far as to leaving it plugged in during the swap over of machines. It's worth a try.

VSDISPLAY 15" touchscreen monitor (model VS150ZJ01-T) works with the G3 controller. There's a minor quirk where if you close out of a pop-up window (for example, the spindle controls menu) using the touchscreen instead of a mouse, the window might open up again a few seconds later. Otherwise, all of the other touchscreen functionality seems to be good.

I also tried the iChawk and Cocar touchscreen monitors - the image quality and viewing angles on the iCHawk and VSDISPLAY are significantly better than on the Cocar, which starts to wash out as soon as you're not looking at it straight on.

I am trying to find the screen you're referring to, is this the one?
Just found this amazing item on AliExpress. Check it out!
US $176.72 | 15" 1024x768 Industrial Resistive Touch LCD Monitor H DMI VGA DVI Input Port 15inch Lcd Touch Monitor


I didn't find much by googeling the part number in your post...

I suspect that you have no experience in programming, specifically embedded systems.
Understanding and implementing something like the USB protocol is likely to require a full time developer.
The relevant USB specification document is 79 pages long:


The protocol does not appear to specify how multi-point touch screens report however the USB HID protocol (which covers mice) implicitly imply:
Only the first three bytes of the USB mouse report are defined. The remaining bytes, if existed, may be used for device-specific features.

And so every vendor does whatever they feel like...

And to add to Zombie's reply
Microprocessor's software storage memory is not infinite, so if they even added other touch screen support, they would be taking away storage from other features that the users have asked for, as is the case of the old G2.
