Re: Wiring multiple Roboclaw with Nvidia TX1

1. Confirm the NVida has 5v tolerant I/Os. If not use a 3.3v pullup instead. 2. It shouldnt matter if you are using a pullup from Jetcon power or from the Roboclaw 5v rail(unless Jetson is not 5v tolerant). If Jetson is not 5v tolerant you will need to pullup from the Jetson power rail. Yes you can ...

Re: Adafruit Feather M0 compile issue

Yes, you will need to use the hardware serial port and remove the softwareserial.h from the example to compile for ARM based arduinos. Also most ARM based arduinos have more than one hardware serial port, eg serial1,serial2,serial3...etc. You will need to find out what pins are for what ports and th...

Re: Adafruit Feather M0 compile issue

You will need to check if software serial is supported on the Feather. Not all arduinos have software serial support(eg Due, Zero). Is this the Adafruit Feather 32u4 Bluefruit LE module? Because that is based on the Atmel32u4(same chip as leonardo uses). That chip only supports software serial on a ...

Re: Roboclaw poower supply

I would not recommend using 22.2v on a 12v motor. I also would not recommend regulating 22.2v down to 12v. Its unlikely you would be able to do this with enough current capacity and you would have to wire up something to handle the motor regeneration which would make the project extremely complex. D...

Re: Wiring multiple Roboclaw with Nvidia TX1

1. If you are only controlling one Roboclaw(not multiple units on a bus) then you wire the MCU TX and RX directly to S1(to MCU TX) and S2(to MCU RX). The roboclaw outputs 3.3v signals on S2 and is 5v tolerant on S1. To user seperate 5v power, just do not connect the 5v line from the MCU to the Roboc...

Re: Adafruit Feather M0 compile issue

Please download and use the latest arduino library. The latest version takes a SoftwareSerial or Serial pointer as an argument. See the bareminimum example for the syntax for use with a hardware serial port.

Re: Firmware problems with RoboClaw 2x15A V4

The configuration was reset when the firmware was updated. The mode by default is set to Packet Serial mode. You just need to change the mode to RC mode(and possibly enable mixing if you are using a differentially steered robot).

Re: RC controller recommendations

I would look at hobbyking for a reasonably priced controller. Get 2.4ghz. Probably dont need anything fancy. Most controllers will easy handle 300 feet. Much more than that and it get hard to see what you are doing but most controllers can proabbly go significantly further than that. You need to see...

Re: Wire size and motor type

To test if the inductance is too large on the wire you need an Oscillascope and you need to run two tests. One with short power wires and one with long power wires. You need to watch the voltage on the battery at the robotclaw screw terminal. If the voltage ripple is significantly higher on the long...
