Re: Command to read both encoders at once?

Yes, the current firmware(release version) is 4.1.16. The QA version is 4.1.17 but may have bugs(hence the QA). We encourage people to use the QA release and report any problems they may find. At this point we are nearly ready to make the release version 4.1.17 but we are going to hold off a little ...

Re: Motors Overheating While Stopped

1. If you are hearing buzzing the PID settings are too aggressive causing the motor to constantly be oscilating(eg having power dumped into it). Reduce the PID settings some and/or add some deadzone so when the motor reaches the 0 point and there are no external forces pushign against the motor it w...

Re: USB Roboclaw Windows Driver & IonMotion 1.6.6

I also use Atmel ICE and have not had any conflict so that shouldnt be a worry. If the USB is installed correctly it will be under Ports in the Device Manager. If it isnt installed correctly it should be under Unknown Devices or something like that. If the board is not being seen at all, fist try re...

Re: Command 46: doesn't complete full move.

1. I do recommend you make sure the encoder isnt getting bad counts. I've seen several motors with integrated encoders that were designed wrong(snubber circuit is wrong), causing a large amount of noise on the encoders 5v rail and signal lines. The noise was bad enough to cause false counts. I use a...

Re: USB Roboclaw Windows Driver & IonMotion 1.6.6

IonMotion 1.6.6 will crash if you try to connect when no Roboclaw has been detected and it wont detect the Roboclaw until USB sees the board. In the Device Manager do you see any unknown devices? Also do you hear windows ding when you plug the Roboclaw into the PC? Note the roboclaw must be powered ...

Re: Packet Serial over USB

Yes, the USB port can always be used for packet serial commands, whatever the mode of the board is set to. Two limitations. If the mode of the board is set to something other than packet serial mode then the other mode has priority for driving the motor(eg RC mode will prevent motor movement command...

Re: Command to read both encoders at once?

The manual has not been updated yet. It usually takes longer to get that updated than the sample code and libraries.

Re: Python examples misunderstanding

The Position Settings button on the Left will open the window that lets you setup and test position control. You will need to tune the settings correctly for your motor. There is a section in the Roboclaw manual that talks about manually tuning and using the autotuner starting on page 56. Have you c...

Re: Feature Request: Comprehensive status read?

I will look at it. We are near the point were adding new features would require removing older ones so it may not be possible.

Re: Feaature Request: Limit Wind-up

Currently there is no option to adjusted the integral maximum in velocity control. The integral maximum is back calculated based on the PWM duty cycle. If the new integral would cause the PWM to saturate(eg go over 100%), then the previous integral is used instead. Also the integral is leaky. If the...
