Any variable pitch circuits out there ?

[heffalump]

Hi,

I have a need for a circuit to drive the pitch servo on my reversible pitch system to two discreet points depending on throttle position. So, for throttle >50 % the pitch servo will go to one posiiton and throttle <50% the pitch servo will go to position 2.

Any lead on some pic code or circuit will be appreciated.

Thanks
Josh

Josh,

There is enough code in this thread (http://www.rcgroups.com/forums/showthread.php?t=630746&highlight=free+avr) to build what you want with an 8 pin AVR. If you need help doing it just PM me.

I can modify a standard PiStix to handle that for you pretty easily. No charge for the change. Just order one online and give me a couple days to get it out to you. www.rc-hydros.com
