2/8/2018 Teensy Loader app for Ubuntu Linux
https://www.pjrc.com/teensy/loader_linux.html 2/4
The Teensy Loader should appear as a small window. If the Teensy board is running the LED blink, or
not connected, you should see this window.
If HalfKay is running, you should see this. If not, simply make sure your Teensy board is connected,
and press the pushbutton to run HalfKay. The Teensy Loader will quickly recognize it.
From the File name, choose "Open HEX File" and open blink_fast.hex, which you downloaded using
the link at the top of this page. You can also open the file using the toolbar button, or using drag-and-
drop onto the upper portion of the window. When the file is opened, the filename and percentage
usage of the Teensy's memory are shown.
Select "Program" from the "Operations" menu, or click the Program button on the tool bar. The
download should be very quick, perhaps too fast to see a tiny progress bar appear, but you should see
the "Download Complete" message.
