help need with brains and modio feed pot
« on: March 21, 2008, 05:38:14 AM »
hello i using 3 analog pots on peter modio feed,rapid override,spindle override,
they all have steps eg on the feed  and spindle are 0,20,30,40,50,60,70,80,90,100,110%
rapid is 0 , 25,50,100%

feed is on analog 3, slave 1 i have work this bit out as address 8 ,config 1, serial set up etc

on the brains i can get the 0 -1024 bit aok

so how can i get this to set the steps up

one way i can see is

analog3 is less then eg20 the set dro to 0

analog3 is more then eg20 less then 120 set dro to %20

this will work but their is a lot of rungs to do, is their a formula to do it. i have gone thick and don't have a place to start from.

please help or some one post me some sort brain they have done so i have a start

thanks Adrian locker

Hi Adrian,

As you are not using a constant spacing between steps, i.e. 0, 25, 50,100 a formula would be difficult. It would be easier to just do a set of comparison rungs and be done with it.

Cheers,

Peter.
