Which electronics are needed

Hi, I´m just wondering if you use a buffer circuit for the communication with the motors?

I found nowhere in the code the possibility to specify a direction pin which is used to switch between send and receive. So I tried to set the "readback_echo" of the serial_proxy to true and connected Rx and Tx directly with the dataline but it doesn´t find the motor.

I have only developed and extensively tested this code with usb-to-serial-type adapters (e.g. USB2Dynamixel). Some people used other hardware configurations, but I can't speak for those.
