Arduino Library - Unimplimented/Undocumented commands

I have been going through the library code and inserted comments, page numbers, and location of documented information. Several of the udocumented commands may be just reserved/empty, but I would like to know if there are any usable undocumented commands not discused in the RoboClaw or MCP User Manu...

Arduino Library, Documentation, and Updates

I have been working on my project again, after a long hiatus, due to a new baby. I have been interested in documenting and updating the Arduino Library and have started with the un-named enum at the beginning of RoboClaw.h. I have modified it in the following way. (Doing all this, as described below...

Re: Questions about the safety wirings

This is one example that may help. Here is how I have done this with my design, which is most likely different than yours. I am expecting stall conditions on 1000W max rated motors (40+ Amps at 24V DC - each motor) so finding a circuit that suits the need for safety is a must. I am using an MCP263 m...

Precharge Resistor, is soldering OK?

I am using a pre-charge resistor across the contacts of a constant high current relay as shown in the lower middle of the photo (green resister and metal can). I've never wired one before and would like to know if I can solder the wire to the resistor (8 awg wire) or if I should use a crimp contact ...

Encoder Placement & How does the MCP263 read the signals?

My main question, How does the MCP263 read the rotary encoders, is based off of some testing of the encoders I did before connecting them to the MCP263. When I tested my encoders which are 600 Pulses per rotation, my microcontroller can read both rising and falling edge of each channel giving me 2,4...

Thank you for clarifying. The data sheet doesn't state that unless I missed it.

TVS Diode Selection?

Hello again, I am having some difficulty figuring out an appropriate TVS Diode that will be appropriate for my intentions. I did a google search and found some notes by MicroSemi (PDF) on this process. To be honest, I have no idea how to perform all these calculations. I just want to get my project ...

Python, no definition to call serial.close() to close the serial port.

I read through all the code and documentation of called modules, like serial , and I don't see any definition for a call to "serial.close()'! I see at the end of "roboclaw.py" a call to open: def Open(self): try: self._port = serial.Serial(port=self.comport, baudrate=self.rate, timeou...

RE: Votlage Clamp Mosfet Recommendation

I've spent a bit of time trying to find appropriate parts for my application for the protection circuitry on page 8 of the datasheet and Page 40 of the manual. I am using an MCP but I think this applies to ROBOCLAW's as well, so I am posting here because this part of the forum is more active. Info a...

Printed Manual

Hi, Just posting because I ordered, and received, a printed manual for the MCP series from Office Depot's printing services. I ordered a basic spiral bound black and white copy for $24.00USD but they made a mistake and gave me a color copy, valued at about $65.00. I am quite impressed with how it ca...
