Re: Issues with 4.2 firmware

This was a regression. 4.2 on some models was not checking if Main battery was over 5.5v. This has been corrected and 4.2.1 firmware is now available.

Re: Limit switch on 2x7a does not work

Firmware 4.2.1 has been released. I'm not entirely sure I understand the problem you are describing but give the new firmware a try and let us know the results.

Re: Roboclaw CRC Errors during getting encoders

You are getting this because the GETERROR/GETSTATUS command has changed. See this post: viewtopic.php?f=2&t=924

You will need to modify the python code in the ROS Node to use the changed GETERRORS command.

Re: RoboClaw and motor ratings

We recommend not using motors with stall current more than 5 times the peak current rating of the Motor controller. So 11amps(assuming you are putting both on a single motor channel) is well below 5 times the peak current rating of the 2x7a or any of our other controllers.

Re: Additional response bytes received

command 74 is SETPINFUNCTIONS. Your code only sends the address, command and settings for S3, S4 and S5 mode. That command also requires a CRC16 checksum as do all commands that send data. Since the packet is invalid you wont get any ack byte back. Based on your previous post you are getting an ack ...

Re: Heart Beat/Motor Stop

Simple and Packet Serial have a timeout option. If communciation stops for that amount of time the motors stop. RC mode(MCU option disables this) will shutdown the motors if RC pulses don't arrive at least every 100ms. Sorry, but on Roboclaw there is currently no Analog equivilent to a timeout. On M...

Re: Motor controller in an I2C system

Sounds like a noise issue. I2C uses pullups. Try using stronger pullups. If you are relying on the internal pullups on the Arduino that is likely your main problem.

Re: Packet Serial without library

One suggestion. I'd recommend people modify the library if they are size constrained rather than write something from scratch. There is a lot of error handling code in the libraries we write for a reason. You can easily remove all the unused commands but I'd recommend keeping the underlying function...

Re: RoboClaw 2x15A Cooling Fan Speed

Currently there is no direct control over the fan. It is entirely controlled by board temperature.
