PIC Servocontroller?

I have build this controller:

Why this controller? because with this one i can controll 4 RC servos and 4 outputs.

But this controller is SH*T

first the communication don't works alright. after a couple minuts the controllor don't works anymore and need to reset.

also the 4 outputs are SH*T... if I move a servo the outputs goes off/on too..

and i can't change the source to turn de servo for 180 degrees, it works only 90 degrees. (I have this servo controller too :

by this controlle you can choose with a jumper between 90 or 180 degrees)

So Í'm searcing for a other Servo controller, for 4 servo's and with 4 outputs....

Don't have to be a 16F84, maybe is a 16F628 better?

Is there maybe somebody with a source? or is there somebody thats want me help to write it?

(sorry for the bad english!...)

Below is a servo control chip setup I put together for a webcam pan/tilt gizmo that works reasonably well and is fairly cheap.

Hi Arjen,

Have a look at the XCSB servo library. You can download a fully functioning LITE version of the library that is restricted to 4 servos and will run on a

16f628, 16f876 and 16f88. You can download the LITE version of the XCSB compiler (which is free for non-commercial personal use) and build your own servo controller. If you need to change the servo library, you can buy a copy of the STANDARD servo library which allows up to 32 servos to be controlled concurrently and comes with the source code.

Have a look at

for a demo circuit and ready to run hex executable using the XCSB servo library

Arjan, there several other multi-channel servo controllers around, one of which is mine, and which I believe will do everything you're after, and more ....

Their Servo Coprocessor is easy to build and controls up to 9 servos.

A great bargain for under $20
