Title: xbee, ssc32 e i2c... how to connect them togheter?
Post by: mauro.rolly on July 29, 2007, 11:23:31 PM
Hi!

I am developing a mini robot (a rover with a robotic arm) and I think to use a ssc32 to control the servos, and the md23 (it uses i2c) to control easly the rover. All connected to an xbee, so to control it wireless (wifi) with a Personal Computer.

I would like to know if I can connect all of them togheter in parallel mode or if I need something like some buffers, pull-up resistor, etc?

Thanks in advance for any answer

Best regards, Mauro

I have built a wireless rover ,my butler robot. Check my blog for info.( the newer version of my robot will be posted soon)

Basically I used a laptop and Phidgets to control relays which control the motor. In your case you could get a mini-ITX board with wireless card attached. But that approach is only if you are going to include devices which require fast processing power on your robot.

If you decide to use the Xbee then look at what this guy did. http://www.shelato.com/SecurityRobot/

My servos are goin to the digital output pins.

Instead of xbee Im using bluetooth . . . but basically hook that up to the UART.
