 FIRST is like pizza--you and I might prefer different toppings, but there's no wrong way to do it. - Billfred [more] |

Re: Vex Servos
On most servos the 1 to 2 ms will not give the full physical range that the servo is capable of. This is done so that any physical shock will not force the shaft to go to the physical stops. You can get more range out of some servos by sending pulses shorter than 1 ms and longer than 2 ms. I did this for a IR ranging sensor. The Hitec servo in the FRC KOP is capable of slightly more than 180 degrees.

Re: Vex Servos
Yea I jsut wasn't sure what the max range is to use (safely). for using the continous rotation servo I am running it at about 122 Hz and have a range of about 5 bits on a 8 bit timer. I was thinking of bumping up to a 9 or 10 bit timer to increase resolution, in the servos range.
But I now successfully have a VEX robot running off a Atmel uC! I just need a bettery good enough to supply the power for 4 servos!  -John |
