Mecrisp is a native code Forth implementation for MSP430 and ARM Cortex M.

------------------------------------------------------------------------------

You can choose to compile to flash or to ram, and it generates native code 
with folding, inlining of short words and it opcodes common instructions. 
Note that it doesn't need to save any pointers.

Hopefully it should be completely interrupt-save and you can hook your 
Forth definitions to interrupt vectors.

Altought it is in spirit of ANS, there are some differences: Be careful.

For details, have a look at README files included !

Mecrisp is a play on words, it comes from MSP and french "écris", 
which means "you write", in the sense of "you write to the MSP430".

Special projects included here:

mecrisp-ice... runs on Lattice HX1K and HX8K FPGAs.

mecrisp-across... is a new still highly experimental Forth cross compiler
                  for small MSP430 targets featuring global optimisations.

Target literature package for... contains a collection of necessary and
                  useful datasheets for your favourite target chip.

loran-c... contains an experimental software defined Loran-C 
           longwave radio navigation receiver running on STM32F407.

mecrimus-b-0.5.tar.gz is the latest bit-bang USB code for MSP430.

wuseldraht-scurrywire-0.1.tar.gz is an implementation of a
           field bus for combined power and data transmission
           over long, high capacitance wires.

All other packages contain ancient code for those interested in history...
