good morning everyone

I have a problem. I am a student, and I'm doing a project for semester, a robotic arm.

the problem is the following :

I would use Dynamixel servomotors especially the AX-12A, I want to control by means of pic18F4550 and using a program in CCS.

but I find information about it

anyone can help me please, an example, someone who has already tried

please help

thanks for your help

You haven't even tried to search at all have you?

There is lots of info available for the AX-12...
Try searching here and on Google and to earn your
grade rather than us doing it for you.

To get you started here is the manual for the servo.

Here is a tutorial:

It is controlled using standard serial at 5v. So it really is just a matter of sending it the bytes you need. #USE RS232 can drive it directly.
You just wire the TX and RX line on the UART together, and connect this to the data line on the device. Remember though that used like this you will receive every byte you send, which makes parsing the replies harder work. Alternatively a simple TTL buffer can be used to switch off the receive when sending, and implement buffer control on the PIC, as if you were using half duplex RS485.
