You schematic can be much simpler if you get an auto direction-sensing shifter; i used https://www.ti.com/product/TXS0108E. You don't need to mess with the direction pin at all. Power the chip A side with 3.3V, B side with 5V Hook Teensy pin 8...

In answer to the above. I can report that it does in indeed work, but with two changes: in the Dynamixel2Arduino library in /src/utility/port-handler.cpp -> void SerialPortHandler::begin(unsigned long baud)..., line 53 change...

I would like to use a Dynamixel servo, using their TTL serial protocol, with the Teensy4.1. There are a number of posts covering similar topics from some time ago, but more recently the half duplex capability of the native UART was added to the...

Just wanted to update on this. Between cutting the ISR to just recording a timestamp, and then reducing the order of the IIR filter I was able to get really great results and almost no instability. So the Teensy 4.1 is fully capable of acting...

If you aren't sampling at a fixed rate you can expect issues with DSP on the sample stream. Whether this is what you are seeing its hard to guess from the information available. What is this "regular instability" like? Graphs? Jitter in the...
