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.
Choose "Reboot" from the "Operations" menu, or click the Reboot button on the tool bar. Your Teensy
board should immediately begin running the fast LED blink program!
To try Automatic mode, simply click the "Auto" button, or choose "Automatic Mode" from the
Operations menu. The Auto button should illuminate bright green. Then, open the slow LED blink HEX
file.
