Forth for the micro:bit
There was an opportunity to have early access to a spare BBC micro:bit.
Matthias Koch took the time and effort to adapt his Mecrsip-Stellaris Forth to the BBC micro:bit hardware.
The complete Mecrisp Github File System contains many files covering the different Controllers it runs on – but which are not necessarily related to the micro:bit.
We want to make it easy to get to the stage of running the first Forth code on the micro:bit.
As result here a Starter Pack.
Suggestions to improve it are welcome.
How do you install Mecrisp onto the micro:bit?
- The Serial Interface needs to link with TeraTerm1) software making the PC a display and keyboard for the micro:bit. Make shure you installed TeraTerm. Now get the Starter Pack with:
- The Mecrisp Forth hex file to throw into the microbit folder on the PC for programming the micro:bit.
- A small example VFXTESTAPPbit.f ASCII file adapted to the existing Microbit Mecrisp Hex File,
- The same VFXTESTAPPbit file as Doc for own documentation and extension.
- More documentation about the small VFXTESTAPP Forth starting example for PC just using 35 Forth Words with explanations can be found here.
- And you can try the VFXTESTAPP example on the PC without any micro:bit by just downloading and starting the vfxtestapp.exe
- micro:bit IO Connection Documentation generated by Matthias Koch as there are no official schematics.
More I/O Discussions about the micro:bit in English and as well available in German ( not including Forth but a lot of IO information ) as supporting information and part of the Forth Bookshelf is here.
Have fun trying it out and feedback for additions and improvements can be sent to Juergen Pintaske at epldfpga@aol.com
