Since Forth<br>is sitting in an interesting spot between compiled and interpreted<br>modes, it'll also be soon possible to do livecoding directly on the<br>device. But even without that, Forth is naturally fitting, as well as<br>sufficiently compact & highlevel to succinctly define stacks of DSP<br>operations (i.e. synths)<br><br>I've started with an STM32F401 dev board, but meanwhile have focused<br>on the new(er) STM32F746-DISCO to also be able to generate UIs for the<br>synths.<br><br>Audio samples:<br><a href="https://soundcloud.com/forthcharlie/sets/stm32f4" target="_blank">https://soundcloud.com/forthcharlie/sets/stm32f4</a><br><br>Project summary:<br><a href="https://cdn.hackaday.io/files/9374401057216/20160215-synstack.pdf" target="_blank">https://cdn.hackaday.io/files/9374401057216/20160215-synstack.pdf</a><br><br>Project log:<br><a href="https://hackaday.io/project/9374-stm32f4f7-synstack" target="_blank">https://hackaday.io/project/9374-stm32f4f7-synstack</a><br><br>The current implementation is written in 95% portable C, but am in the<br>process of rewriting it in Asm to avoid the overhead of C calling<br>conventions (it will still be embeddable in C project though). The<br>Forth VM incl. a bunch of native audio operators is ~24KB, the core<br>dictionary (basically the system library, most of Forth is written in<br>Forth) adds another 8KB, but will grow to probably double that.<br><br>I'm planning for an initial open source release in April, but just<br>wanted to share the project with you already. Furthermore, I hope it's<br>okay to do so here, I'll be running 2 workshops about this in April<br>too.
