Re: RoboClaw 2x60A (V6C) Low Logic Battery Error on startup

I have had the same problem with my 2x60A. I have solved it by the following settings for a LiFePo battery 24V (full charged 29.7V and empty 22.5V): Max Main Battery 34.0V Min Main Battery 22.5V Main Battery Offset 0.0V Max Logic Battery 34.0V Min Logic Battery 5.5V Logic Battery Offset 0.0V You hav...

Re: E-Stop function does not work as expected

After testing it and does not found a solution or any updates from Basic Micro, I have built my own E-stop circuit with some transistors. Now my system will shut down if my microcontroller sends a LOW signal. After power on again and the fault is repaired, the system is working again. The other way ...

Re: E-Stop function does not work as expected

I have tested now the normal motor commands M1 (0 and 1) and M2 (4 and 5) and also the duty cycle commands M1Duty and M2Duty (32 and 33). Exactly the same problem as with the mixed commands. The E-Stop turns one motor at full speed after setting pin S3 LOW. I will try to install the legacy version a...

Re: E-Stop function does not work as expected

Where can I find the MixedDuty commands in the manual? Or what command I have to send instead of 8/9 and 10/11? But it would be great if you could solve that. I need the mixed commands for my robot. Edit: I have found it I think. It is the command 32/33 for motor 1 and motor 2 with the values from -...

Re: E-Stop function does not work as expected

After testing a bit, when the motors both turn at the left side in mix mode, the E-Stop works perfectly. When the motors turn to the right, forward or backward in mix mode the E-Stop will set one motor at full speed and stops it when the Roboclaw E-Stop pin is HIGH again. That is for sure an issue. ...

E-Stop function does not work as expected

Hello, I have updated my Roboclaws today with the new firmware 4.2.1. Now I have tested the E-Stop function on S3 (with my Roboclaw 2x60A), but when it is pulled low during the motors turn, one of the motors will go full speed and is out of control until i reset the Roboclaw or power it off and on a...

Re: Motor controller in an I2C system

I have tried pullups from 1.6k to 4.7k, no difference. After that, I have installed a LTC4311 between the I2C connection what makes it better, but the same issues after some seconds.

Re: Packet Serial without library

I have got it working. Since around three months it works perfectly and is a lot smaller in its size as the whole library. The issue was, to declare at the beginning in the setup a forward/backward and right/left command to initialize the motors. I have made it a bit shorter and now that is the work...

Motor controller in an I2C system

Hello, I have tried to use a Roboclaw 2x60A or 2x7A in a project with three Arduinos. The Arduinos are communicating over I2C. If I connect the Roboclaw to an Arduino and send a command over serial TX/GND to S1/GND of the Roboclaw, the I2C blocks and does not works until a reset of the master Arduin...

Packet Serial without library

I have tried to write the code for sending commands with an Arduino Uno over packet serial with the checksum without the library. The reason for that is, because I have tried to use the example and copied the same commands into my code to get it working. The example seems to work, but with the same ...
