yes noise is an issue for 14 bit its 1.8khz , much quieter at 16khz and 10 bit res fosc is 32mhz (8meg rock *4pll)

I need to make a better test bed 600ma from the l293d is a bit limiting .

got the pid routine under 500us worst case using floats . I find that floats are easier to work with (mentally) for experimenting with but will go back to ints when I have things sussed out.

I'm not sure how I will go about implementing variable velocity or accel yet. I was just really happy to get " pid lock " and good position control to start with.

ps using the microchip c floating point library adds 8k bytes to the pgm its huge
