Thread: Simple method for communicating with Teensy2++ from Linux PC

    Question Simple method for communicating with Teensy2++ from Linux PC

    Hi,
    My problem is this:
    I need to send simple commands from (a quite outdated) RedHat Linux 5.1 machine and Teensy 2++.
    Some of the standard drivers do not exist in this edition.

    One thing I was able to accomplish was to build the Teensy command line loader, load and run compiled hex file. That worked just fine.

    But now I'm not sure how to actually control the board.
    I've assumed a serial connection would be the easiest, but there's not /dev/ttyUSB device.

    I don't really care about the implementation (serial, usb, midi) as long as I can send simple control messages to the Teensy.
    Perhaps use something similar to what the teensy_loader_cli is doing?

    I'd love to hear some ideas
    Thank you.

    - cli loader works fine
    - dmesg shows:

    usb 1-1: new full speed USB device using uhci_hcd and address 19
    usb 1-1: configuration #1 chosen from 1 choice
