Re: Adafruit Feather M0 compile issue

There are two different Feather boards from Adafruit. One is atmega32u4 based and the other is Arm M0 based. No Arm based boards support software serial at all currently(it may not be possible to bitbang serial on an Arm processor).

Re: Roboclaw 2x7a Read Error Python

For USB connections, because USB uses seperate connections, this is how you do it. Eg you need to know which USB ports are being used. However, you can read the Packet serial address back from each unit to auto detect which unit is conenct to each port. For the TTL connections, The 2k ohm resistor i...

Re: SpeedAccelDeccelPositionM1 goes crazy with accel decel values

One cause of this is mixing non-encoder commands or velocity commands with position commands. The position commands keep track of the previous position to calculate when to start/stop accel/decel when executing position commands. If other commands are using in some situations, the next position comm...

Re: Python mixed SpeedAccel command not working

I will test it when I am back in the office next Tuesday. Please email support@ionmc.com with this problem as well.

Also make sure you are using the latest python library direct from our website and have the latest firmware installed on your Roboclaw. That is what I will be testing with.

Thanks.

Re: Currents reading (and control)

We make it so you can read it quickly if necessary and have a reasonable idea what the instant current reading is. However current changes in milliseconds(usually 10s to 100s of millisceonds) so reading slower isnt really a problem if you just want to know what the average current draw is over time....

Re: Backward / Reverse with SpeedAccelDistanceM1 Function?

Im sorry you have to send the board in to be updated but at the time that board was built we did not have an infield upgrade option and it is so old that I dont know why it is not working with the old arduino library. If the boards are the old design without the USB connector(Which I assume they are...

Re: Beginner Robo-Claw Issues

1. There is a section on using the buttons to change the mode and options of the Roboclaw in the manual, specifically pages 15 through 18. 2. The default analog mode will autocalibrate when powered on. Where ever your POT is set to when you power it up will be the "Stopped" position. If yo...

Re: Currents reading (and control)

1. The current readings are from a single pass digital filter. Samples are taken each PWM cycle(20khz). Minus noise the read current will equal the actual current within 16 samples.

2. Torque control mode is not offered on the Roboclaw.
