Teensy Loader Application
The Teensy Loader makes getting
code into your Teensy easy. Just press and release the reboot
button and the processor runs the HalfKay bootloader, which is automatically
detected. Teensy Loader lets you download your code and reboot to it.
Automatic mode downloads and reboots to your code the instant your computer detects HalfKay. The latest version of your code is always used. Just press the button and within 1 to 2 seconds your latest code is running!
Software Development Tools
WinAVR C compiler.Teensyduino, add-on for Arduino IDE.
Simplified USB Examples or Dean Camera's LUFA library.
Breadboard Usage
The Teensy is available with header pins, for direct no-soldering-required use on a breadboard, which can also be run from the +5 volt from the USB cable. Standard Teensy boards come with solder pads. Either way, all Teensy boards come fully assembled and tested, so no surface mount soldering is needed.

The 128x64 Graphics LCD can be used with Teensy 2.0 and Teensy++ 2.0 and Teensyduino using this GLCD library. They fit together nicely on a single breadboard.
