Hello,
I want to add the Arduino Mega 2560 to a chain of Robotis Dynamixel motors (MX-106R, MX-64R and MX-28R). The Arduino will be connected through a RS-485 breakout board and Serial1 (or 2, or 3) or SoftwareSerial (http://arduino.cc/en/Reference/softwareSerial). The chain is controlled from the PC (Ubuntu 12.04 LTS, ROS Hydro) via a FTDI USB-RS485 converter. I can perfectly find the chain of Dynamixel motors, but setting up the Arduino to act as a actuator/sensor proves harder than thought.
What have I tried:
- verified communication over RS485; 2
Putty terminals, one connected to
Serial COM of Arduino and one
connected to USB-RS485 COM, no
problems there.
- Tutorial of rosserial, all works fine, but only over Serial port of Arduino and not Serial1/2/3 or SoftwareSerial.
So, what would be the simplest method of setting up a node with an Arduino over serial communication other then Serial0?
How to publish to Serial1/2/3 or SoftwareSerial?
