To add to the list, PicoBit Scheme for microcontrollers, currently PIC18 and ARM, https://github.com/stamourv/picobit There was a port of one of PicoBit predecessors, Bit Scheme, to the XMOS architecture, with realtime GC and support for…

The PIC18 can run the following Scheme implementation: https://github.com/stamourv/picobit (The (last of the original) main author(s) has stopped maintaining it, although there are many forks, some of which might be maintained, I haven't…

…just requires some engineering effort and there is not much demand for it. Btw, there is picobit( https://github.com/stamourv/picobit ) which can be run on micro-controllers.
comment by xfer · 2017-10-03 · in Gerbil – An opinionated dialect of Scheme designed for systems programming
…Scheme is okay, but almost none of them are truly small anymore. Even the ones like picobit ( https://github.com/stamourv/picobit ) require quite some grunty support from a desktop machine outside the processor.

Don't forget Picobit which is Scheme: https://github.com/stamourv/picobit
comment by bsder · 2015-07-27 · in JerryScript – A JavaScript Engine for Internet of Things
…your point stands. Requiring 64K of RAM puts this above most ARM Cortex M0 chips. Picobit ( https://github.com/stamourv/picobit ) sits comfortably in 16K ROM/4K RAM. There's no good reason why Javascript vouldn't do the same.

…several Scheme implementations now built for microcontroller/embedded use, Picobit for example: https://github.com/stamourv/picobit

Also picobit for scheme goodness: https://github.com/stamourv/picobit Doesn't support full numeric tower (no floats), but does implement 'unbound precision integers'. See §5.1 of this paper: http://www.iro.umontreal.ca/~feeley/papers/StAmou…

If you are interested in this, check also PicoBit: https://github.com/stamourv/picobit
comment by Kototama · 2015-06-11 · in Reviving Lisp for smaller programmable machines
Looks like PICBIT is finally open source: https://github.com/stamourv/picobit We use(d?) it at U of Montreal to drive small PIC18 robots. Except for the one time I had to debug its GC, it was a fine platform, even for HS students.
