Re: Using multiple roboclaws with an Arduino

For each Roboclaw you will have a unique class object. That object knows which pins are being used to communciate to the specific Roboclaw. So you can safely use the ReadSpeedM# commands. Since you are using 2 physically different serial ports you can use the same packet address for each roboclaw. Y...

MCP Limit switch pullups/downs

When using a pullup on a MCP I/O pin(or pull down) please keep in mind the internal voltage dividers on each pin. They are 1200ohm series and 2200ohm parallel. This means each I/O has an impedence of 1200ohm and any pullup will need to be stronger than 2200ohm and low enough to pull up above 2v. A 1...

Re: RoboClaw Solo 300: issue with RS-485 control on S3

RS-485 has a bug in the current firmware. We have been working with a few other people to fix the problem. We currently have a couple different RS-485 adapters we will be testing as soon as time permits. We made some modifications to the firmware so the pin does not change before it should be there ...

Re: How to use the same input to start and stop?

For that you will need to write a small MCL script. The actions can only be used for a single action per I/O.

In the script you will need to keep track of the last state. You will probably need to have a startup routine as well that will determine what the state of the door is.

Re: What's the difference between safestop and off?

With safestop you have to bring the control back to 0 before you do anything else. For example if you safe stop while using an analog joystick.

Re: Odd Speed Readings Of Motor Speeds with 2x7A

Speed will go to zero when the motor stops. Note the Speed reading is a 1 second average. The ISpeed reading is the 1/300th of a second instant speed. If you have noise on your encoder inputs you could get an instantaneous speed of up to 9.8 million. Enough noise could cause the symptom you describe...

Re: Limit reading and actions at limit

Use the Read Status command. The WARN_S4 and WARN_S5 bits indicate the current state of the limit switch for motor 1 and motor 2.

viewtopic.php?f=2&t=924

Do you have the latest firmware installed? What mode do you have the limit switches set to in General Settings?

Re: "EN1" only ticks at high speeds. Tick count wrong

Please take pictures of the encoder signal lines on an oscilloscope and email support@basicmicro.com about this. If the encoder signals are clean and noise free then it could be a problem with the encoders(excedingly rare). Noise is the usual cause of problem. This is especially common on motors wit...
