Suggest Bsp instead of BS unless it's a shortcut to my code

No number keys?
Function keys after pressing Fn I asume?

But it looks Nice and compact. Could replace your picocalc design when touch works well enough.
If you need not redraw the keys often you could even put real artwork. Maybe you can find hires scans of Casio FX720 or similar.

Problem is the keypad scales to the resolution so it will even work in 320x240, numbers are on the sym(bol) toggle. I'm just deciding whether these should toggle shift, sym and ctrl should toggle like a lot of on-screen keyboards or use multi-touch.

PS. The final S/W will be a bluetooth host/usb/hdmi build so you can select between the onscreen keyboard, physically connected usb keyboard or a bluetooth keyboard. S/W for this will be released next week. I'm assuming any of the cheap HDMI 1024x600 screens 7" or 10" will work as long as they have the USB touch capability. The frequency will be fixed (252MHz) which should allow me to run 1024x600, 512x300, 640x480, 320x240 all as modes available without reboot

Demo running 1024x600 with font 3. Switching to mode 3 for the gui demo (512x300).
Apologies for the dithering and video quality

Peter,

this is so cool! Now it is even more "stand-alone" and self stustained! Not even a real keyboard needed! Wow!

Greetings
