Servo Control with Propeller

AJM

Hi Everyone,

I must admit that I've only marginally searched for a solution to this question. With all of knowledge everyone seems to posses on this board, it's just easier (and faster) to post the question here.

I am reasonably new to the propeller. My only previous experience with micro-controllers was with a college class for micro-controller interfacing using basic stamps about 2 years ago.

Currently, I am interested in controlling several servos; I am aware that there are several servo objects in parallax's OBEX. My question is whether it is more beneficial to use the propeller to control the servos while receiving sensory data or to use a servo controller board that would receive data through serial communication from the propeller.

Thanks in advance

AJ -

It all depends on your application and system design. If you have the pins available in your design to run the servos directly then I would recommend doing that. There is plenty of processing power in the Propeller so there isn't a worry there like other microcontrollers. However if you have so many I/Os attending to other things like sensors and such, then maybe you will need to consider an additional servo helper device, but then my recommendation would be to add another Propeller.
