V6.03.00RC16
PicoMiteRP2040V6.03.00RC16.zip

VGA/HDMI USB builds have additional touch panel support.

non-VGA/HDMI builds now support GT911 capacitive touch controllers as well as FT63x6 controllers. VGA and HDMI builds do not and will not support direct GT911 touch controllers. You can buy a very cheap I2C to USB module for any screens that use a GT911 and don't already have the touch over USB

All builds except PICOMITEMIN, PICOMITEVGA RP2040, and WEBMITE RP2040 now support touch gestures. Obviously only multi-touch controllers support expand/contract/CCW/CW/double tap gestures but even resistive XPT2046 TFT screens now support swipe gestures.

All builds except PICOMITEMIN, PICOMITEVGA RP2040, and WEBMITE RP2040 now support two new touch functions TOUCH(XN num) and TOUCH(YN num). Setting num to zero in either function will return the number of current simultaneous touches. Setting num to a non-zero value will return the coordinates of that touch.
e.g.

Dim x(10),y(10)
Do
If Touch(yn 0) Then
For i=1 To Touch(yn 0)
x(i)=Touch(xn i)
y(i)=Touch(yn i)
Next
Pixel x(),y(),RGB(white)
EndIf
Loop

I'm not aware of any previously reported bugs in this release

Coming soon:
HMDIBTH firmware. This combines HDMIUSB and bluetooth LE host functionality allowing for small self contained computers to be built with wireless keyboards and trackpads

Wow – this genuine n-Multitouch is just absolutely brilliant!

Minor update to WebMite RP2350 to support RSA encryption - see Wolfram Alpha thread for more details/example. No version change

Last try. If this doesn't work then I think we have to assign that monitor as "non-supported". Every other touch monitor that has been tested AFAIK now works. You should see two devices connect. The multi-touch digitizer and a USB touchscreen. Make sure you test without a USB mouse also connected. It may be that only single touch via the USB touchscreen works but that would be a win.

We have a response to touch!!

When Pico powered up and USB-touch attached I get the following:

NOTE that the last line appears after a delay of about a second - then sits there.

When I touch the screen (1 finger) and move it around, I see:

GUI TEST TOUCH works for single finger, and with 2 fingers will respond to the 'last' finger (although difficult to see for certain as the screen fills up with data making it hard to see the touch-pixels.).

UNPLUGGING the usb-touch results in:

Multi-touch Disconnected
> USB Touchscreen Disconnected

And reconnecting USB touch seems to now re-initialise correctly (i.e. I do NOT see the previous 'device limit reached' error).

I will now try the FW you posted at the top of this page in the hope that will work too (but without all the debug messages!!)....
