I am trying to run Hitec D-series servos (D950TW, D89MW, ...) digitally from a PC using TTL signals, as described in a white paper by Hitec "D series SERVO (TTL/ RS485) Protocol Manual" and I am not able to get it to work as described/expected.
- only 1 command from all works (kind of, angle)
- return signals look differently than described in document
Has anyone have ever success with it ? Please let me know to get in touch .
