Thank you for the explanation! I now better understand why 5V voltage can damage Teensy 4. I will be more careful in handling I/O voltage so as not to damage the chip. Thanks for the insight and advice! 🙏😊

Thank you for the explanation! I really appreciate this information. I will be more careful in the future not to damage Teensy again. If there are any additional suggestions to prevent similar mistakes, I am very open to hearing them. 😊🙏

Thank you for the answers you have provided. I'm starting to understand what to do, but I still don't fully understand about half-duplex, is there a simpler language to explain half duplex? If I use that mode, will it affect other serial communications? Please correct me if I misunderstand this...

Thank you in advance for the various discussions you have shared in this forum. I have also read some of the related topics that you answered, such as: Teensy 4.0 dan Dynamixel page 1 Teensy 4.0 dan Dynamixel page 2 Dynamixel and Half-duplex serial usage on Teensy4.1 Rs485 halfduplex for...

I am trying to control a Dynamixel AX-18A servo using Teensy 4.1 via Serial2 (TX: pin 8, RX: pin 7). For half-duplex communication, I am using IC HD74LS241P as a buffer between Teensy and Dynamixel. However, I ran into a problem where the servo did not respond to the commands I sent. I've...

I just continued the pre-existing circuit, I don't know where they got the source, but yesterday they used STM32F407 and STM32F401 Blackpill which have the same output as teensy. They use Dynamixel serial library and work on STM32*. I have also tried using 5V voltage ( I also read references...
