Hi -
I am new here -
I've been trying to control my pixel strip via Teensy3.2 + Madmapper. I was following this tutorial online, - everything went fine, but when I try to connect my teensy from Madmapper preference window, Teensy does not appear on the Out LED device list
I was able to upload the file via Teensyduino, example file works but I cannot find my teensy on the list....
Is there someone who has any idea on this ? Tips? Thank you in advance !

THe teensy will not appear if the serial port to communicate with it cannot be opened. Please close teensyduino, it certainly keeps the port opened and both apps can't use the serial port at the same time

Hello, I am new here too
I have the same problem, I can't see the Teensy (v4.1) in Madmapper. The code transfers well, and the LEDs light up with the test code. (the code I used https://github.com/CaseyJScalf/MadMappe ... Teensy.ino)
I tried leaving Teensyduino and Teensy Loader, restarting the computer, changing the usb C port and usb hub port, but nothing happens.

The information that may help :
In Teensyduino the path is: /dev/cu.modem128377801 Serial (Teensy 4.1)
My configuration : MacBook Pro with M1 Pro under Mac OS X Ventura (13.1)
The teensy is plugged on a USB C port through a hub

Thank you in advance !
