Re: Emergency stop from Atmega chip

Use a MixedDuty command with 0 duty value or wire an extra I/O pin to S3 on the Roboclaw and set S3 to be a non-latching E-Stop. Set the pin high when running normally and pull the pin low to e-stop. The seconday I/O pin is probably the safest for a true e-stop situation since it wont rely on valid ...

Re: 24v Input for both Motor & Logic?

We dont recommend running higher than 18v on the old 5a but the linear regulators are rated for at least 30v so you can run 24v even on them. It will just get really hot(the regulator) which will bleed heat into the rest of the board. For efficiency sage using a seperate external switching 5v regula...

Re: Novice Velocity PID Instructions?

The basic manual tuning description is shown in the Roboclaw manual. Basically you start with a low value of P and zero for I and D. For velocity control D will most likely remain 0. You then increase P until the motor runs close to some setpoint(eg speed) you specify. What you rae looking for is to...

Re: using S3 & S4 as home switches

One correction. The S4 and S5 pins are available for home signals. Not S3. I just re-read the tital of the post and realised that.

Re: 24v Input for both Motor & Logic?

Based on the maximum voltage settings I assume you are using a Roboclaw 2x7a? If not please tell me what version you are using. I beleive the default setting for the 2x7A is 18v max on the logic voltage whether that voltage is coming from the main battery or a seperate logic battery. Youcan change i...

Re: Advice on Roboclaw Size

You have two options. 1. Assume the motors will stall at maximum duty cycle so 133amps * 4 motors is what you would need. Easiest to assume this but would require a massive motor controller. 2. Assume the motors will not stall at or near maximum duty cycle. The maximum current draw will depend on ho...

Re: using S3 & S4 as home switches

Once the home switch triggers the movement command will be finished. However only that command will be removed from the buffer IIRC. So if you sent a home command(eg move -30000000) and a command to move forward 10000 it should move backwards until the home sensor triggers and then execute the 10000...

Re: Python mixed SpeedAccel command not working

Good. That version of the command gives you individual acceleration arguments instead of one common one IIRC.
