  • socz80: A Z80 retro microcomputer for the Papilio Pro FPGA board

    Will put together this amazing project that will knock your socks off! Its a Z80 implementation for the Papilio Pro that runs CP/M, MP/M, and UZI operating systems. It’s based on the T80 core from OpenCores and has some great additions such as using Hamster’s SDRAM controller for heaps of memory. This may be the…

  • Yet Another VGA generator by Offroad

    Offroad put together a cool project that can be used to visualize and debug your projects. Think of it as adding a boat load of RGB LED’s to your project. 🙂 There is full source code included in the forum post.    

  • Hamster uses a Papilio Pro to test out the Logic Analyzer feature on his Rigol 1102D

            Hamster puts together an interesting to read wiki page that puts his new Rigol 1102D to the test. He uses his trusty Papilio Pro to generate the test signals and includes full VHDL source and some great screen grabs from the Rigol 1102D. The Rigol 1102D looks to be perfect for…

  • Animated VGA Shapes – No Framebuffer

    Check out this cool project that Corey Kosak published in the forum: Here’s a project that draws animated shapes on a VGA screen without using any memory! It even includes collision detection. I thought I’d share my third project with you all. I got sort of obsessed with the idea of driving the VGA protocol…

  • MatthewH puts together a simple SDRAM controller for use with the Papilio Pro.

    Papilio user Matthew Hagerty put together a very nice implementation of a simple SDRAM controller for the Papilio Pro FPGA. Written in VHDL, it sacrifices some speed for ease of use and simplicity. After all, not every project needs to use the full capacity of the SDRAM chip. You can read about his epic adventure…

  • Spartan 6 FPGA in the “Bus Pirate” form factor.

    Rob, over at ultra-embedded.com, pointed us to his new FPGA project; a Spartan 6 FPGA in the “Bus Pirate” form factor. What’s really cool about the project is there is no expensive USB chip, instead Rob uses a low cost USB PHY and a USB core connected to his AltOR32 implementation. A small USB stack…

  • MicroBlaze MCS: Attaching Peripherals

    Following up on the previous blog post about setting up the free MicroBlaze MCS soft processor for use with the Papilio we have Jim’s second tutorial showing how to attach a peripheral to MicroBlaze MCS. In the tutorial he shows how to attach a PWM core to the GPIO pins of the MicroBlaze MCS for…

  • MicroBlaze MCS: Step by Step tutorial for the Papilio

    Jim, a new Papilio enthusiast, put together this really great tutorial on how to get the free Microblaze MCS soft processor up and running. While playing around with the WebPack ISE software he realized there was a free soft processor – the Microblaze MCS. Not a fan of the Arduino IDE and its lack of…
