Re: Configuring an MCP236 to use encoders

There are only 2 pins per quadrature channel. If one pin is set both will be set to quadrature mode. Whether those pins are A or B is entirely up to how you wire them and the motor power wires. Once you setup the pins as quadrature and wired your encoders you will be able to see the quadrature value...

Re: Quadratic encoders - voltage issue

We do plan on changing those values on a future revision. Even though many ST pins are 5v tolerant not all are(specifically the A/D capable ones) and we have A/D pins multiplexed to most/all the user accessible pins. That means all/most user pins need internal voltage dividers, clamping circuits and...

Re: Arduino library command for getting signal values of inputs?

The Get Signal Values command is the only way to get the state of input signals via packet serial. That command is not recommended for that purpose though because it dumps the status information for all pins at one time(eg it takes a relatively long time). Writing a custom MCL program that does this...

Re: reduce maximum velosity in rc

There is currently no setting to set a maximum power/speed. When using Analog or RC controls the full power/speed range is mapped to the controls full range. We plan on adding this functionality eventually but we are currently busy with testing new revisions(changes required due to the parts shortag...

Re: Tune RC 2x7A by Serial/Python?

Autotuning is the one function that can only be done through the USB and Motion Studio. The Roboclaw only executes low level routines and the autotuner brains are all in the Motion Studio software. I recommend sending the damaged controller in to have the connector replaces. I recommend NOT trying t...

Re: Having trouble getting absolute or quadrature position working

You no longer need to set the QPPS before autotuning the Position PID or cascaded Velocity/Position PIV. Pots are much worse then incremental encoders. For potentiometer based systems I usually recommend manually tuning. This applies to very low resolution incremental encoders too. If the autotuner ...

Re: Inconsistent voltage readings from RoboClaw Solo 300

The USB 5v bus is causing a slight change in the 3.3v power rail. This rail is also used to measure the battery voltage. The reason this is happening is the 5v is clamped through a 100ohm resistor and diode. This will be corrected in the firmware. Basically we can detect when the USB is connected an...

Re: Packet Serial without library

I have allowed your post, but support will not be able to help you with your code. We specifically provide the library(with source code) because this is a non-trivial thing to do. Instead of trying to write your own code, I recommend you walk through our library. The code to handle actually communic...
