Papilio One Wiki Page

The Papilio One is a Gadget development board based on the Xilinx Spartan 3E FPGA (datasheet). It has 48 I/O lines, dual channel USB, integrated JTAG programmer, 4 power supplies, and a power connector. It provides everything needed to make Gadgets using Arduino compatible sketches or standard VHDL/Verilog. Hardware can be added without any soldering or bread boarding using the provided "Wing" slots. The Butterfly One places the focus on bringing Gadgets to life rather than reading through datasheets.

Guides and Tutorials

• Papilio Quickstart Guide
  • This Papilio Quickstart Guide covers the basic of installing the drivers, making file associations, and running a "Hello World" application on the hardware.
• Xilinx Webpack Quickstart Guide
  • Get started writing your own VHDL, Verilog, or Digital Logic for the Papilio Platform with the free Xilinx Webpack software. This is the most powerful but most difficult method of coding for the Papilio boards, the sky is the limit with what can be done. Find a core on Opencores.com  and integrate it with a soft processor core using the powerful Webpack software.
