Re: 2 microcontrollers, 1 roboclaw

I was using a wall wart style connection on the pi but have switched it to being powered thru the 5v supply of the roboclaw with no change. The only connections to the pi are for the switch (ground and pin both from the gpio with physical pullup to 3.3 rail of pi), the usb connection to the roboclaw...

Re: 2 microcontrollers, 1 roboclaw

I am not using a usb isolator. Could this be a ground path loop issue?

Re: 2 microcontrollers, 1 roboclaw

I have one raspberry pi using packet serial to a roboclaw via the GPIO Rx/Tx pins and all is working fine on that one. I have another raspberry pi hooked to the same roboclaw via USB which is having the problem. The problem is the one and only one GPIO pin using to determine whether a switch is bein...

2 microcontrollers, 1 roboclaw

Is it possible to use two raspberry pi (or any other device) to control one roboclaw (particularly the 2x30)? background: I have a system that was set up with one raspberry pi 3 B+ and a roboclaw 2x30a. It works fine for about 95% of what I need. However, one subsystem causes the programming to have...

Re: micro switch

Thanks for the response. I will send an email. In the meantime I can still accomplish it thru a relay after the roboclaw to accomplish what I need until this function would be able to be added.

digital potentiometer

Is there any reason a digital potentiometer set with a 2 volt range wouldn't work in place of an analog one when in analog mode? I was wanting to use something like a MCP4151. I had searched throughout the forums and outside to find where it had been done before without any results. I could change t...

micro switch

I purchased a roboclaw 2x30a in order to replace two other motor controllers I was using. The setup uses a micro switch in order to reverse the direction of one of the motors. When the switch was in the NC position, it goes one direction. When it is the NO position, it goes the other. I'm not concer...
