How do you set up the software for the resolution of your system with gecko320's. Is it one step per pulse of the encoder you use?

What is the best PPR encoder to use? 300, 600, 1800?

If I use 1800 PPR encoders can I set the software up that 1 step = 3 pulses from the encoder? I wouldn't need such fine resolution.

Thanks

A G320 will multiply the CPR of an encoder by 4 times. So if you have a 250 CPR encoder it will take 1000 pulses to turn the motor one full turn.

Is that multipier fixed in the gecko or is it user selectable via jumpers or something.

I have 2, 300 PPR encoders and 1, 1800 PPR encoder.

The G320 is fixed. The G340 I think has some way to change this value but I have not ever used a G340.

Ok thanks Jeff. I looked again and all my encoders are 300 PPR.

I hope they will work. I also home my P166MMX can dish out that may pulses....
