1024 instructions? At that point I'd probably just use assembly. At that size, it would still be manageable.

Hmm, maybe that's the fundamental difference in thinking; the people I'm thinking of would reach for the simplest tool that can feasibly handle the job, even if it's somewhat harder to use.

In those 1024 instructions I was able to fit a decoder for standard 433Mhz remotes control, with learning of remotes (stored in EPROM), a button, a rotary encoder input, and a dozen led outputs through a 16 bit shift register. It also controls a digital potentiometer. Used to adjust a power supply output voltage driving a 20 meter LEDs string.

I am sure a pure assembly implementation would have saved some room in the FLASH, but the generated machine code wasn't that bad for what I can tell with my limited experience anyways. And it sure was nice to write it in Rust. Except a codegen bug in the version of Rust at the time ;) That one was painful!
