  • 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,…

  • 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…

  • Papilio One running a Sharp LCD

    Hacklab, based out of France, has been hosting weekly hacking sessions with the Papilio One FPGA board. One of the neat demos they have done is driving a sharp LCD with the Papilio One:   They report that getting Frogger to work is the next goal!
