The whole thread seemed weird to me.  I can run eForth on those 60 cent
dev boards using this 21 cent STM8 cpu that appears to have three PWM
channels:

I didn't read the whole thread, but who on earth needs to mess with
doing PWM in software?  Also, if you PWM LED's, they flicker.  Usually
not enough to notice if you light something steadily with them, but if
you look at a moving one you can see the strobing.  It's no big deal.

Even that notorious 3 cent Padauk processor has PWM:

Sheesh.
