    The newPath2D: word is used to create a word which then functions as a FORTH constant. Example:
    s" ...svg commands..." newPath2D: myDraw
    To display myDraw it must be preceded by the position x y in canvas. Example:
    10 10 myDraw

    I tried to flash development board „WeMos D1 ESP32 R32 WROOM-32 WiFi”
    using the procedure you've described on your page, the flashing utility reported it has been done, but — unfortunately — there's no answer when
    I started the terminal.
    Is the binary from your page unsuitable for WROOM variant?

    Oh, I forgot — when I press „boot” button it spits out error message:

    OK, I managed this somehow. So here's the correct procedure
    how to flash your Forth while working within Linux environment,
    using esptool.py:

    1. If the devboard got messed up — like I spoiled mine, trying to
    follow the procedure you've described on your pages — firstly
    there's a need to reinstall the bootloader. The bootloader I used is
    the one to be found in the file available at https://download.espressif.com/esp_at/firmware/ESP32/ESP32_WROOM/ESP32-WROOM-32_AT_Bin_V2.4.0.0.zip
    (the file bootloader.bin in the bootloader sub-dir)

    a) Erase the flash memory:
    esptool.py --port /dev/ttyUSB0 --chip esp32 erase_flash
    b) Flash the bootloader into memory:
    esptool.py --port /dev/ttyUSB0 --chip esp32 write_flash 0x1000 bootloader.bin

    Of course if the board in use shows up at different port than USB0,
    that need to be changed in the spells listed above.

    2. Flash the Forth files:
    esptool.py --port /dev/ttyUSB0 --chip esp32 write_flash \
    0x8000 ESP32forthV70610_extended.ino.partitions.bin \
    0x10000 ESP32forthV70610_extended.ino.bin

    Yes, now it seems to be working at last. Testing two different devboards.

    Does there exist any doc to ESP32Forth? Any „reference guide”
    or anything like that? I hope not just these few clues listed on your WWW
    pages — and the whole rest one needs to guess?

    That is pretty cool ! I’ve not done much on the graphical side of things… but looks like a promising path to test and experiments.
