[Amforth] A RISC-V update

A risc-v update for CH32V307 AmForth-RV can now compile to flash directly rather than saving a word already compiled in ram as before. This is better and much more like the approach taken by the AVR code base. However, it does need an mcu that is able to do this. The flag field in the dictiona

A RISC-V update. AmForth-RV is now self-supporting (no C libraries required) for the WCH CH32V307. Source and a pre-built hex file are here [0] Best wishes, Tristan [0] https://tjnw.co.uk/amforth-rv ___ Amforth-devel mailing list for http://amforth

[Amforth] A RISC-V update

A risc-v update. Getting there [0] It can run ISRs written in both (almost pure) Forth and C [1]. There is has an evolving transpiler from Forth to ITC speak and the save and see words are now more robust. Some toolchain and building documentation has been added [2], and the beginnings of a c

Re: [Amforth] A RISC-V update

Thanks for the update! Both the board and the experimental AmForth-RV implementation look really interesting. I'm curious how you're planning to use the compiled C object support. I can see that being helpful to access existing high-level building blocks for things like USB. Is it possible to g

[Amforth] A RISC-V update

A risc-v update. AmForth-RV update Good progress made with the CH32V307 [0] Words defined in the RAM dictionary can now be appended to the FLASH dictionary so user defined words (individual words or the entire RAM dictionary) are able to survive a reset. This was one of my major milestones and
