I've just put a fix into the PicoMite that turns off OPTION ESCAPE while it reads in the regex and then restores it.

Quote int tmp = OptionEscape;
OptionEscape = 0;
strcpy(p, (char *)getCstring(argv[2 + n]));
OptionEscape = tmp;

both for instr and linstr

Will we see the new PICOMITE Ray tracing subsystem in the 6.0 version for CMM2? That would be an amazing addition. I'm very impressed with that. It Just popped up out of nowhere as far as I can see. That guy is amazing.

Just installed b11 and keyboards that didn't work before are now working.

However, in every version I have tested, I get "Unknown command" when I try using VAR SAVE. Is there some trick that I'm unaware of?

VAR was left out during conversion to 16bit commands.
It will be restored in Beta12.

The next task is implementing Structures, after that I will ask Peter's advice on which of the recent Picomite enhancements might benefit the CMM2. e.g RAY casting.

Many, many thanks, Gerry

This is such a freaking awesome development. I remember when you first mentioned CAN but I don't recall CAN FD

Soooo many possibilities with this thing

Thank you! I am eagerly looking forward to the Structures!

One thing we don't have on the CMM2 is touchscreen support. I'm already looking at the RP2040 bridge solution, using the Arduino tiny-USB code to interface the USB touchscreens to UART.

Reading about this code, there are two modes; mouse and digitiser. Mouse produces relative X and Y values of +/- 127 whereas the digitiser (touchscreen) produces absolute 0 to 4096. 12-bits but there is also mention of possible 16-bits.

I wonder if the CMM2 mouse handler is similar to this(?)

I don't mind going the bridge route but it means losing a precious UART.

Can CMM2 use SW UART.?

You only get touch screen support in MMBasic with LCD displays anyway. There are no drivers of any sort for them with other displays.

I think you'll have to decide on the touch layer then consider the hardware and firmware. The touch screens themselves have their own resolutions which don't necessarily match the display resolutions. Then you need to figure out the driver chip for resistive or capacitive type - they need different hardware handling.

The problem with SW UART is no RX buffer

Mapping is no problem. My DOS system is mostly EGA 640 X 350 but for some pages, flips to VGA 640 X 480. The MicroTouch sensor has a resolution of 1024.

Readtouch(xcoord,ycoord,touch)

If touch then
.

.
End If

PC monitors with capacitive touch are dirt cheap.

The touch technology is irrelevant because the USB just spits-out the data.

If you have something in between as a controller then it can issue an interrupt on touch then the main processor can go and handle it. No need for a RX buffer so you can use I2C or SPI or SW UART.

Hi Mick,

Yeah, I've been thinking about "something in between" but more along the lines of the Teensy 4.1 as it is now supported by SmallBasic. Its eight UARTS are exciting for me because UART shortage gives me anxiety

especially now that Gerry has incorporated CAN (and CAN FD) on the CMM2. The Teensy 4.1 also has an SD card which gives me the option of backing-up the CMM2's SD.

And then if SmallBasic gets around to supporting Ethernet.....

Could be the ideal in-between solution
