Re: Problem with Serial communication

1. Did you enable multi-unit mode on all the Roboclaws?2
2. What baudrate are you using?
3. Does communications work with a single Roboclaw without first connecting via USB? Eg only one Roboclaw connected to the RPi serial port.

Re: Roboclaw 2x120 RC Connection

S1 is pin 8 and S2 is pin 6 of the CTRL connector. Connect those to the signal pins of your receiver. Connect pin 5 of the CTRL connector to a GND pin on your Receiver. If you want to power your receiver from Roboclaw 5v connect pin 3 of the CTRL connector to the PWR pin of the Receiver. It is not e...

Re: Roboclaw solo A30 No Write Setting!!

I assume you mean Solo 30A. Please be more descriptive on your problem. The Write Settings option is in the Device menu. Or are you trying to write settings from a packet serial command? Is something not being written or is nothing being written?

Re: position control of a non linear movement

You dont need to use many buffered commands. I would recommend, for your requirements, always sending the next command, buffered, a bit before the previous command completes. This way your new command will start exactly on the end of the last command. Otherwise I would suggest using non-distance com...

Re: How fast can a Roboclaw process commands?

You should set a 10ms timeout on any serial write, if you are using a try except on any commands. The Roboclaw will timeout and clear any garbage left in the packet receive buffer so you can start a new clean packet. This is how the write commands are already setup in the library though unless you m...

Re: RoboClaw 2x15A Motor Controller (V5E) - Freeze/Hang

A real serial port write will never freeze or timeout(unless there is something wrong with the PC) because we dont use flow control. USB virtual serial ports are different. If there is a problem they can cause a Write to hang. USB does NOT like noise. DC motors produce a lot of noise. USB is not con...

Re: How fast can a Roboclaw process commands?

I noticed this line: import roboclaw_driver.roboclaw_driver as roboclaw At a minimum you have renamed the Rooboclaw python library or you may be using something completely custom with similar function names. Please email support@basicmicro.com with this program and the modified library. I'll look at...

Re: position control of a non linear movement

The distance commands can be buffered. Eg send several and as the distance is reach for the earlier command the next command will start to execute. You can also use the GetBuffers command to determine when the last buffered command is executing so you can send more distance commands to the buffer.

Re: RoboClaw 2x15A Motor Controller (V5E) - Freeze/Hang

Please contact support@basicmicro.com. We have a prerelease that may help out(reduced command latency). The change may be related to your problem or not. We have not had any reports of this kind of problem so it may be unrelated but lets check if you have the same problem with the pre-release first ...
