Arduino IDE with Minimus

Introduction

This is how to load Arduino sketches to the Minimus AVR stick without modifying the bootloader.
As the hardware is identical to the teensy 1.0, any sketch compiled for the teensy will run on minimus.

The Teensy runs a closed source bootloader which isnt available.
While it is possible to create a custom bootloader to make the minimus appear as a Teensy, this method doesnt require you to flash a new bootloader.

* This is a bit messy as Im copying from my hand written notes, I'll tidy up as I go along

How To

* I last tested this with older versions of all software involved. Will test with latest versions and link to older versions if this doesnt work.

* This assumes you already have the minimus working with Flip loader

1. Install the following
   1. Arduino IDE
   2. Teensy Loader
   3. Teensyduino
2. Launch Arduino IDE and Teensy Loader
3. Select Teensy 1.0 under Tools, Board
4. Load/Write your sketch and click verify
   • Behind the scenes, Arduino IDE will create a temp folder containing the .hex file to load onto the AVR
5. Find the .hex file and load onto the minimus using Flip loader.
6. Reset the minimus
7. Profit

Finding the output hex

From the Arduino site The .hex file is the final output of the compilation which is then uploaded to the board. During a "Verify" the .hex file is written to /tmp (on Mac and Linux) or \Documents and Settings\<USER>\Local Settings\Temp (on Windows).

If you are still having troubles finding the file you can use a disk monitoring application such as DiskPulse to look at files written during the verify process.
