See PR #266

After change config.devider from 1 to 2 with reference to pr262 I can confirm the amounts of steps are correct. Also the timing seems to be correct.

The stepper motor stops after 10 revolutions and 10 seconds exactly.

test envirement

stepper motor 1.8° 1/16 step

s1 = stepper.attach(pio.GPIO12, pio.GPIO13,200,1000,1000) s1:move(160) -- move 10 revolutions t1 = os.time() stepper.start(s1) print('time used in sec for 10 revolutions:',os.time()-t1)
