Output settings for 16F88

Thanks skimask!

Yes I did miss your point; of curse the "squarewave" must look better to the 5804 if the duty is more like 50/50!
New code:

for a = 0 to 2000 ‘ ten turns
ST = 1 ‘ start pulse
for b=0 to 28:next b ‘ on time
ST = 0 ‘ end pulse
for b=0 to 28:next b ‘ off time
next a ‘ loop

The motor runs at the same speed as before, perhaps with a little less noise. If I try to go below 28 it loses torque and I do not help to use different on and off times. I have tried both ways, shorter on time and shorter off time.
S**t, I really thought this was the solution!

You *might* get a little more speed out of it if you ramp up to speed (i.e. set an acceleration rate) rather than instantly hitting the full speed.

But, as Skimask said, steppers are designed for low speed, and once you hit their top speed in the circuit, the motor will stall...which is a nice way to stay stop.
