Parameterizing skywriter with MicroChip's Aurea software

Hi there,

I just got the full sized Skywriter board, and have got some basic examples working with an Arduino Uno. I'd love to debug and tweak the MGC3130 with microchip's Aurea software. As far as I can tell, there are two ways to do this:

1- Use the i2c to USB bridge bundled with a microchip kit (Hillstar / Woodstar ). It looks like the way the bridge connects to the chip / board should be compatible with the skywriter, using 4 wires + 2 for Vcc and GND.
2- Have the Arduino (or a Raspberry Pi) act as an i2c to usb bridge itself

As I'd rather not having to spend $170 to get the kit just for the bridge, I'm wondering if anyone has had success with method no. 2, whether via an Arduino or Pi host. I've tried downloading some generic i2c to USB bridge sketches for the Arduino but had no success getting the Aurea software to detect it.

Thanks!
