I am pretty new to Dynamixels as a whole, but this question involves purely the Open RB 150
I have been trying to use Serial 2, or the serial port on top of the board to do UART communication to an Arduino Nano (Eventually a Teensy), and I can’t seem to get any messages to send or receive. I have used an oscilloscope on the TX pin of the Serial, and there is no change when I attempt to send a message over it. I have tried this on a second Open RB that I have and the same issue. I have a feeling that there is something I am missing programming wise.
I can currently use Serial 3 to send information to the open RB, but when the Arduino receives information from the open RB, it is corrupted/ or not what I am intended to send. I have double checked that they are both on the same baud rate for communication. ** edit I found the issue with reading the data from Serial 3 was a software problem on the Arduino side .
Currently I have the code set up to take in a message from the USB port and echo it to the Arduino attached to either serial 2 or serial 3. Any tips or advice would be greatly appreciated.
