The slow start and stop isn't always what I want. <BR/>My idea would be to LookAhead in the step list, see how much lower or higher the next step is, if next value is lower: reverse voltage at the end of the step as a break, if next value is higher: apply full PWM value for faster speedup. Also have a StepDifference value, updated each step, to use as an equivalent to an Envelope to ease tapespeed to required value. <BR/><BR/>All this in a 16th of a measure may be overkill, havn't tried this yet. I'm so slow in coding and debugging, but so far it seems that reversed voltage CAN force the motor to an ermm... faster slowdown. Or reverse direction. Startup lags even with full voltage applied. <BR/><BR/>Well, first I will continue tracking down all your sketches to download them. They're great, thank you for sharing.Anonymousnoreply@blogger.com
