... Now, it works :?

It seems that the ports were unusable right after the WinXP install, but their reinstallation allowed to correct the issue !

Let's do some programming, now ! :P

By the way, this is some of the mechanic (in an ugly background, I confess ^^)

I installed WinXP and VisualC++ on the Roboard,and, of course, I want to control my servos with it.
I have a problem with this part :
Using either the AX12 example or the Dynamixel SDK For Roboard I could find on Roboard.com, the servos won't move.

As the examples "speak" at 115200BPS and the servo's default configuration is 1MBPS, I tried changing the servo BaudRate with an Arduino and the Dynamixel Configurator, but 115200 BPS isn't a valid BaudRate !!
I just can choose 111111 BPS or 117647 BPS !

I really wonder how the example on RoBoard.com can move an AX12 at 115200 BPS, since AX12 can't handle this speed (it's written in the doc of the servos).

Anyway, I tried to only send 1 Byte with the Roboard, and listen with the arduino (I shortened TX&RX as said in the Dynamixel SDK For Roboard .PDF).
I dont receive anything :shock:
I tried several port, nothing !
But my project is properly configured, compiles, and when I launch the program, there's no problem in the opening of the COM port !

Would someone have an idea about these problems ?

Thank you
