but those device don't have much of a processor inside. i assume it can behave like those many (FTDI or Prolific provided chips for a) USB-to-serial converter. its software defined what the Teensy board offers on the USB port - thus get the right firmware and you can have a bunch of options what the PC thinks the board is. common device types are HID devices for mice, keyboard and more, printers, cameras, networking adapters and many more. The Teensy board acts as a USB device (at least that would be the normal case) and for this it reports as being sort of a (often freely selectable) device type. There might be a little misunderstanding on your side - lets point it out: further there is some USB functionality on board for interfacing with a PC.
TEENSY DRIVER WINDOWS NOT WORKING SERIAL
You thus might refer to a microcontroller board with an ARM M4 processor core built in and a bunch of peripherals also in the same housing, including a few serial ports (seen up to 6 such units in one data sheet).
That far i can see the Teensy board comes in various flavors. You find more information and example code in the Teensy user WIKI:

You can do something like that: Stream& control = Serial Ĭontrol.println(someData) // send data to the PC over the main communication channelĭebug.printf("%d sent some data\n", millis()) // send some debug info on the debug channel If you now want/need some debugging/logging information it is really convenient to use the second port for that and monitor debug messages on a standard terminal (or t圜ommander). it sends commands, receives results etc over this port. (it is generally much more useful as the stock uploader)Īs for your question about the use cases: The multiple serial modes are especially useful if you have a PC application which communicates with your Teensy over the main serial port. T圜ommnander (Alternative uploader) handles these modes nicely and opens a dedicated serial monitor for each of the ports.

In Windows they will show as 3 different serial ports with dedicated COM Port numbers. In dual/triple serial mode the Teensy implements a composite USB device consisting of 3 CDC-ACM (virtual Serial) devices.
