Re: PID Without Direction - How?

we have been using this method for years on our team but this years geartooth counters are only single direction and the pulse width is the same in both directions .

we just decided that +/- 6 inched was good enough on distance and used gyro for going streight . When you have a 40 In. target we dident have a problem hitting it with this method but its still not as accurate as in the past
