Thanks for the update. Just so everyone is clear you must power the Roboclaw directly when using USB. The Roboclaw does not take power from the USB port.

Since we didnt write the ROS lirbary(it was provided free by an end user that uses it in his own projects) I dont know too much about the guts of it. However I'll do what I can. First make sure you have the latest firmware. Also please describe in detail what you are doing in ROS that accesses the r...

Note, you can swap the button functions(Lipo and Mode) using IonMotion(its a check box in General Settings). Apparently yours was not set when it was tested before packaging the board. Also note, that the 4.1.19 firmware(Available in the IonMotion QA software) changes the default button layout on th...

DC motors are usually safe to run at +-50% their rated voltage(too low and you pull too much current which can over heat the motor and too high you can damage the brushes). As suggested in your stackexchange message I would just run the batteries in series instead of parallel, even at full charge th...

We currently dont have C# ot VB/Net samples. However we will be working on some C# samples that show how to use the roboclaw .Net library in about 2 weeks.

Ion Motion will tell you exactly what the error state is. Solid error led usually indiactes a warning(over/under voltagage or over current. My guess is when you set the packet serial mode you may have accidentally changed the battery setting instead. You can reset the board settings(which also reset...

The buffer value will be 0x80 if the motors are idle. Other wise the number returned is how many commands are buffered waiting to run(eg 1 means there is one command waiting to run when the current command finished, 0 means the last command in the buffer for that motor is still running and 0x80 mean...

1. Yes. If the motors are holding position(already stoped) using the Duty cycle command with 0 will stop the PWM to the motors. 2. When executing a Position command a new position command can take over immediately if you set the buffer flag for that command(1 execute immediately, 0 execute when the ...

I wont be able to dig into the library until near the end of this week but I will work up a simple example to initialize the library and run the motor(s). I may not have it ready till Monday though.

Position commands shouldnt be mixed together with other non-Position commands on the same motor. The position commands use an internal variable to keep track of the expected next position for accelerationa nd decceleration calculations. If you move the motor using something else(Speed or PWM command...
