hope this works.. the plan is to use the SoftwareSerial library to bitbang the half duplex serial that the servo needs out the D10 pin
It's Day 7 of the semiautomatic tiny pick and place machine. I need to figure out how to control a dynamixel servo. I want to make a USB bridge so I can experiment with the kinematics. I'm going to try one of these RP2040s to do it.
