Tutorial to connect PWM to any physical pin.

With the flexibility of an FPGA your PWM outputs don't need to be restricted to a specific pin. In fact, Wings are a snap to develop because they aren't constrained by the board they connect to. With this freedom it is possible to write a sketch that uses a PWM on any pin! This tutorial shows the steps needed to move a PWM output from the AVR8 soft processor to any physical location on the Papilio One board.

Webpack VHDL Quickstart for the Papilio Platform

Welcome to the Webpack VHDL quickstart guide for the Papilio Platform. This guide shows how to get a simple VHDL design up and running on the Papilio Hardware. It will cover using Xilinx Webpack to create a project, import a constraint file, synthesize a design, and load the generated bit file to the Papilio Hardware.

Papilio Quickstart Guide

Overview

Welcome to the Papilio Quickstart Guide and the exciting world of FPGA development made easy. This guide covers the basics of installing the software and drivers needed to load the various projects that you create for or download to the Papilio Platform hardware. It also covers loading a basic, "Hello World" bitstream that blinks a pin and outputs an ASCII table over the serial port.
