| Ive added a conditional to the Error calculation.
Basically if im with 0 to 2 counts away from the setpoint just make error =0. Good enough = 0 error jajajaj So basically starting from 0 if i set ... |

| That makes sense... i may be atributing super powers to PID.
However i see in youtube plenty people reaching precision with similar hardware. How can i test this? Should i set this to accept valu ... |

| PWM has to run from fosc/4... so im at the lowest feasable PWM freq. Which impacts my execution time clock so, slower loop times too.
I know its possible to go lower with other osc configurations b ... |

| higher/better power supply did not bring any changes... it settles a bit faster, and the motor gets a bit warm when oscilating.
im having the same behaviour, just faster jejejeje... |
