tl; dr; no, sort of, no, maybe
confused yet?
the short answer is that no, that’s not possible.
The longer answer is that it might be possible, but it’s either limited or hard.
The limited version is to prepare a bunch of styles with parameters, these parameters can then be altered with editor mode, or the proffieos workbench. This can create thousands of different combinations without using up more flash memory.
The UNLIMITED version, is to compile the entire blade style into a dynamically loaded machine code object. It is far more complicated, and is unlikely to happen. Besides, it would mean loading the code into RAM, and there might not be enough RAM to do that.
So far, the strategy has always been two-fold:
- Invent new ways to save memory. This has limited impact, but helps. Of course, every time I save a kilobyte or two, someone comes up with a more complicated blade style. One step forward, two steps back…
- Work on building proffieboards with more memory.
Unfortunately (2) has been severely hampered by the chip shortage, or it would have already happened…
