  • Sneak Peek: VGA Simulator for ZPUino on Papilio

    Here is a sneak peek at the VGA simulator that Alvaro has been working on to verify VGA designs. The VGA simulator is controlled by a sketch and simulates what the VGA output will look like when it will run on the VGA Wing connected to a Papilio board. Up next is making this demo…

  • Mandelbrot generator on FPGA

    Here is a project to create a high performance Mandelbrot fractal generator on an FPGA. Sadly, it does not work on the Papilio yet but maybe the C/RAM Wing will make it possible?

  • Papilio Controlling a Sweet LED Scrolling Sign

    Papilio user GalacticaSound put together a sweet scrolling LED sign that he connected to the Papilio One using a I/O Wing plugged into a breadboard. We want one of those LED signs too! For more details visit his Papilio project page and for now take a look at his video:     Looks awesome Joel!…

  • DAC (Digital to Analog) SPI MCP4921 VHDL project posted by Debreuil.

    Debreuil just posted a github project to control MCP4921 DAC chips with VHDL on the Papilio. There is no Wing for the MCP4921 DAC but there are templates to make Wings in the Papilio Playground or the soon to be available Prototype Wing could be used. Picture of the home brew pcb made with KiCad,…

  • ZPUino Alpha 4 available.

    Alvaro has released Alpha 4 of the ZPUino. Alpha 4 adds support for the Papilio One 500K board. Alvaro has put out a call for any demo requests that people would like to see for the ZPUino on the Papilio One. Don’t miss this chance to request something that you’ve been wanting to see done.…

  • User Project – CNC Printer Control

    Robin Debreuil is working on a sweet project that includes a custom Wing, VHDL code, and a hacked printer. He takes over control of the printer mechanism and controls it with his Papilio One. Seems like an excellent approach for getting high quality, precision CNC motors and slides. Go to a thrift store and pick…

  • Tutorial: Simulate AVR8 and Custom User Cores

    NOTE: Please note that the tutorial does not show that you must select “Gadget Factory Papilio Custom Board” under tools/board in the Arduino IDE for the simulation file to be generated. This screencast shows how to simulate a custom user core connected to the AVR8 Soft Processor. Simulation is the most efficient way to debug…

  • Tutorial: Custom User cores in the AVR8 Soft Processor.

    This screencast provides instructions for downloading and synthesizing a custom AVR8 soft processor for use with a version of the Arduino IDE that has been modified for use with the Papilio. Prerequisites: AVR8 Source Code Arduino IDE modified for the Papilio. Xilinx ISE free “Webpack” version. Custom User Core sketch. Related Simulate your custom AVR8…
