Micro serial servo controller
« on: April 17, 2008, 12:17:23 AM »
Hi there, I'm new to this amazing forum.

I would like to know the benefits of using a serial servo controller compared to driving them directly with the micro controller...

Is it making the ┬ÁC less busy ? (I guess so)

And is there any draw back, like no position feed back or anything ?

Tnx....

all its doing is saving I/O lines on teh uC

instead of the uC doing all the controlling it does the controlling through serial commands
Check out the Roboduino, Arduino-compatible board!

A disadvantage would be that it uses up a uart port on your mcu that you could otherwise use for something else. It does however save up a lot of processing power for something else.

That's what I was waiting for !

I was thinking of using the shiftout system to keep my uart, but dont' know if it'll work, test and trial needed.


Atmega168, already playing with.....
