Press the CONFIG button and ensure you have the proper settings for your version. Check if your version uses 115,200 baud and if it is a model using the old protocol.

nothing, it looks like things are getting to the controller ,but it stops? anyway to send a reset command from your software?

Check the manual for your version of the irobot create. Then press the CONFIG button in the iRobot Roomba Movement Panel in ARC. Select the baud rate and version.

To re-init the roomba, press the INIT button on the movement panel.

still nothing, i'm at a lose what it could be, i've double checked everything, and the irobot create is new..how can I do some checking to the board to make sure it's not the board?

You can connect a servo to port D0 and see if it moves. If it does, then D0 is working. If you accidently shorted D0 out, it could damage the port.

I'd double check your wiring to ensure it's all golden

yup, D0 doesn't work but D1 work with the servo? so now what, How did that happen, I never connected them backwards or anything else.....

Do you have a volt meter?

If so, plug the cable into your roomba and check the voltage on the GND and Signal wire (Black and White) out of your roomba that connects to the EZ-B. What voltage do you read?

k, thanks for all your help, i'll get one tomorrow and let you know.

5v? actually it's 4.96v

is there anyway to use d1 with the create?
