Re: Timeouts on serial line when moving two motors at once
A few more details. We're using 12-volt, 1-amp motors. We tried using a separate logic power supply and it didn't change the outcome.

Timeouts on serial line when moving two motors at once
We're using the 2x7a (firmware version 4.1.24) to drive two motors. We noticed when sending a command to move both motors at the same time in a somewhat aggressive motion we get timeouts on commands that come immediately afterward. Usually there will be a command that times out followed by a few com...

Re: Speed commands don't respect min/max position
Thank you for your replies. One more question: is the MixedSpeedAccelDeccelPosition method considered a position command or a velocity command? It seems to accept both types of parameters.

Re: Speed commands don't respect min/max position
Thanks for your reply, @robof. Yes, I think you are right that using those two commands we could make it work. The down side is the latency that it would introduce to first read back the position and then set the accel/velocity/position. But I will give that a try. Thanks!

Speed commands don't respect min/max position
I have set up the Roboclaw 2x7A with encoders to use the position commands. Everything works well and it correctly stops when it reaches the min or max position I have set. However, these limits are not respected when I use the MixedSpeedDistance command. The Roboclaw moves right past the position l...

Re: Save custom settings to EEPROM
I see. What about commandeering a Roboclaw setting that isn't being used or doesn't apply to the particular board I have? Is that too dangerous?

Save custom settings to EEPROM
I would like to save and read back custom settings to the EEPROM of the Roboclaw 2x7A. The amount of data is very small. I want to save a 64-bit serial number, a 32-bit bitwise bank of flags and perhaps four more 32-bit values. Is there any way to do this? I only need to set the settings occasionall...
