Hi Terry, so it looks like the time has come for me to get a RP2350 pico or alike board and try Mecrisp Quintus on the cheap. But that only after I have spent some time playing with your FURS. Paradoxically, Mecrisp maturity and cessation of its active development may actually increase its use in projects. One doesn't need to look for new updates but can focus on the task at hand instead. I find myself struggling with the habit of frequent checks for the new updates and now this time can be better...

Now, Terry, that is quite something ! Pretty much explains why there were not so many updates on your Mecrisp Stellaris and Across folkdoc pages (or I didn't notice the ones that are there but buried deep inside). In a month or so I should have some spare time to invest in to my little Mecrisp Forth project and this work of yours surely will come very handy. I notice a few oddities like duplicated menu entry for the Wiki which are different Wikis in fact but it is possible I am too picky and do not...

Thank you, Terry. I'll look at the source code and see how it's done in case of the RP2040. Mybe I'll be able to figure out how to do it with STM chips. Looks like I've fallen victim of me not asking my question properly. I should have mentioned STM microcontrollers with flash. A RP2040 or its successor are good as "brains" but have, lets just be kind, very limited analog capabilities. No analog comparators, no op-amps, no DACs. Looks like these are perfect for small robots with external SPI/I2C...

What would it require to run Mecrisp from RAM, not flash ? There are many micros with sufficient RAM (more than 32kB) to enable this feature and leave enough space for the user code at the same time.

Thank you Terry for the valuable thoughts and information. I've been battling uphill all my life so no fears there but .... your input has got me thinking if the effort is really worth the outcome. I think it is sensible to first see how these new chips get used in products (ie. how well received they'll be on the market) and what bugs are unerthed and review the decission then. For now, I'm of the feeling it's not worth a try on my part for the next six months at least.
