Initially this code was tested on a mac
Ensure that you have a working python3 installation
go to a terminal window
type python3
You can install brew and do a
brew install python3 - if it is not installed
The following files are necessary
forth_vm.py
0.txt
These files need to be in the same folder.
You can click on the files in the PyForth notion page(text) and save them as appropriate
pf.py needs to be made executable chmod a+x in the terminal
to start the forth engine type ./pf.py You should get this …

Once this is running on your mac then you can use thonny to transfer the files to your chosen microcontroller.
After copy the 4 files to the target machine, to start forth, then type within repl
import pf
pf.main()
With circuit python, you can add
import pf;
pf.main()
in the code.py file and forth will automatically run when you do a control d.
Any questions / feedback / money (LOL)
