Re: Detecting A 90 Degree Turn

For a wheeled differential steering vehicle, you want the distance commands(the accel versions are better since you can specify the accel/decel rate). But I got the impression this is more for controlling something like a servo. For servo like action use the position commands. Distance commands move...

Re: Roboclaw brushless equivalent

Sorry. Its currently low man on the totem as it were. We've been working on new high power Solo models and updates to the brushed lineup which has taken most of our time. At this point I'd say after the new year before we can finish development and potentially have first production units.

Re: Blanking command

Currently, those commands have not been added to the Python libraries. The command syntax are: Set Current Blanking send: address, 117, percent1(2 bytes), percent2(2 bytes), CRC16(2 bytes) receive 0xFF Get Current Blanking send: address, 118 receive percent1(2 bytes),percent2(2 bytes),CRC16(2 bytes)...

Re: MCP236 close loop currrent control

MCP controllers support current control(using their own onboard current sensors). Setting the Inductance and Resistance settings(see PWM settings screen) enables current control mode on MCP controllers. Duty commands are mapped to current instead of voltage when in current control mode. The range of...

Re: Detecting A 90 Degree Turn

With a properly tuned PID you can just tell the Roboclaw to move X amount or move at Y speed(see position and speed commands). You can, of course, do this all manually yourself. Roboclaw updates its encoder counts 300 times a second. Most commands take 1 to 2 ms to process at 115200bps. But it would...

Re: Python Get a value when limit switch is reached

1. Make sure you have the latest python library from the site. I recommend downloading it again.
2. Please show a simple example program that exhibits the problem so I can check your code and run the example myself.

Re: RoboClaw 2x15A Dual Channel Motor 3.3V logic control

Yes. Roboclaw is 5v tolerant but it is actually a 3.3v device and outputs 3.3v signals.

Re: Concerns over circuit protection with 2x160 34VDC Roboclaw

The protection isn't required, as you found, but is recommended. I usually recommened the pre-charge resistor(or a more complex circuit) when running 24v or higher. Rarely will the inrush cause damage even at 24v but if you power cycle enough from a cold start it can eventually damage something. It'...

Thank you for posting this information. Based on a reply in one of your linked thread: "If one wants to stop this behavior, one should go to "Manage app execution aliases" in Apps & Features, then untick the "python.exe" App Installer box.

Re: Roboclaw 2x60 with servocity super duty linear as servo

I recommend you reset the V6 unit to defaults and setup the settings again. Functionally there is no difference between the V6 and V7 board. We just changed to a new mosfet which lets us cool them better(eg no air gap). The Enable encoder check box only enabled using Velocity/Position control with R...
