- write an OCaml program, compile it, transfer it to the PIC.
Well, actually it demands a little more than just that:
- write an OCaml program, like usually, while keeping in mind that the stack is more limited than usual, same for the heap
- compile it (with ocamlc)
- reduce the binary (with ocamlclean : a bytecode reducer which removes dead-code)
- transform the (reduced or not) binary (with bc2asm : take back not useful zeros, thence reducing the binary size)
- transfer it to the PIC along with its OCaml VM.
Indeed, an OCaml VM has been implemented in PIC18 ASM in order to run OCaml programs on a PIC ! :-)
An example of real program is in the distribution (open source, downloadable from the website):
ocapic-1.3/src/tests/goblet/ (722 lines of ML code).
We also provide a simulator in order to run on a PC (needs X11 (Linux/MacOSX) and GCC) your programs written for PIC18.
The whole implementation has been fairly well tested, however the documentation is still quite young.
