Re: Using 3 roboclaw, packet serial, USB

Hi, Thank you for your advises so far, I have my roboclaws running great together now. I am wondering however if, using python, I can assign values to a single encoder channel? Here is what I mean, is there a function, related to ResetEncoders() that would allow me to do something like ResetEncoders...

Re: Using 3 roboclaw, packet serial, USB

Hi, As I have mentinonned before, I am using 3 roboclaws in packet serial. I have the pull up in place and all the addresses. However from the illustration on page 63 of the User Manual, I see that a connection to all grounds is made. Is that true also when using the USB communication? or is it enou...

Re: Using 3 roboclaw, packet serial, USB

Hi, I have now been able to use three roboclaw in packet serial. My pull up to 5V solution is a little experimental but it seems to be properly connected. However, I am getting some latencies that render the robotic arm I am working on, volatile. I have two actuators on the system that failed the au...

Re: Using 3 roboclaw, packet serial, USB

That's great. I have been getting an error when trying three roboclaws together:
in _sendcommand,
self._port.write(address.to_bytes(1, 'big'))
AttributeError: 'int' object has no attribute 'to_byte'

I don't suppose you have any ideas on what may be triggering this error?

Thanks again!

Re: Using 3 roboclaw, packet serial, USB

Do the Roboclaws have to run the same version to work with each other?
also, where do I get the 5V to the pull up? from the Claw itself?

Thanks!

Using 3 roboclaw, packet serial, USB

Hi, I want to connect three roboclaw in packet serial mode. I am using a USB to connect to the Master roboclaw. Do I still need a pull up resistor for the incoming signal? If so, how would I properly wire this up? also in that set up, I set the first claw to 128, the second to 129 and the third to 1...
