Thank you. I'm a complete newbie and have been a bit overwhelmed by all the new terms and ideas.

FTDI make a series of cables that are TTL level UARTs (So suitable for connection directly to a teensy serial port) on one end and USB-A on the other. To the PC they appear to be a COM port just like any other serial device. This would allow you...

That's good to know. Can you provide more details?

The two Teensy are connected to separate hosts that only have usb-a ports. I asked for advice on the basic idea in another thread before starting and got zero replies. If the setup is bad/dumb it is because I have no experience. This is my first...

Cool, I'll try that. Thanks guys.

This sounds like it might be my issue, but I don't know enough electrical engineering to understand what you said or how to apply it. Will connecting the right Teensy's ground to left Teensy's ground fix it?

They are also connected on digital outputs 0-3 from Teensy #1 going to digital inputs 0-3 on Teensy #2. My problem is, both of my analog inputs on Teensy #2 are getting a value of about 600 when any of the digital outputs 0-3 from Teensy #1 are...

The Teensy running SerialReceive.ino takes serial input over usb from my phone and the Teensy running GamepadSend.ino takes that input and sends gamepad output to my PC. I ultimately want to use my phone as a gamepad with no drivers/software on...

I'm trying to use two teensy 4.0 microcontrollers to translate serial data to gamepad outputs. I have one teensy taking serial data from one host over USB and sending it to the other teensy using the pins which sends the gamepad output to another...
