Butterfly Arduino IDE

Run Arduino sketches on FPGA hardware! This project adapts the Arduino IDE to use the AVR8 Soft Processor and the Butterfly Platform FPGA boards. The AVR8 is an Open Source RISC processor that implements all the registers and instructions of an ATmega103 processor. 

Why would you want to run the Arduino IDE on an FPGA? The answer is rapid prototyping without limits. An FPGA is like a clean slate just waiting to become anything you want. You can do things in hardware with an FPGA that can only be dreamed of on an Arduino. But, it is difficult to design a system from scratch on an FPGA. This AVR8/Arduino project provides an easy to use environment that you are already familiar with that gets you up and running in no time on an FPGA. This provides a great springboard to start exploring the exciting possibilities of an FPGA.

2-Axis Stepper Motor Controller Wing

This is a microstepping single axis stepper motor controller based on Texas Instruments DRV8821 device. It is intended to be used with the S3E Cocoon. It can drive two bipolar stepper motors rated upto 27V and 1.5A, with a simple parallel command interface. The Wing uses a 16-bit Butterfly segment.
