Hm, I didnt think I'd broken stepgen again... It works fine on my
development system. We'll have to debug this one too.
Are you using an unmodified, up-to-date CVS checkout? Are you on TRUNK
or 2.2?

Wait, so is the problem with the pwmgen or with whatever it is that
takes the PWM signal as input?
If you set pwmgen.value to 0.5, do you read 1.65 V with your voltmeter?
