#134860 - sounds like noise to me Responding to: ???'s previous message |
Since it triggers at my input capture
capturing WHAT?????????????????? When i increment/decrement it by 1, the motor seems to not run smoothly. You can tell its going too fast then too slow vice versa something like a resolution problem sounds like noise to me. If all you do is "if too slow speed up a little bit, if too fast "slow down a little bit" the ONLY problem you should have would be that the reaction is too slow. Note "a little bit" should be so little that varying betwwen +1 and 0 should not be noticeable. If you have the motor free running and you have a very small faster/slower step and a simple regulation as above it should be 100% stable once it reaches equilibrium. Erik |

| what is that PWM generated by???? | 01/01/70 00:00 | |
| by motor hall sensors | 01/01/70 00:00 | |
| put a scope on the hall sensor input, is it "spark | 01/01/70 00:00 | |
| looks clean, a little spark i suppose | 01/01/70 00:00 | |
| that depends | 01/01/70 00:00 |
