  • As Simple as Possible – Embedded.FM Podcast interview about Papilio.

    I was invited to do a podcast interview with the good people over at Embedded.FM, it was fun talking about FPGA’s and the Papilio! Thank you for having me on the show Chris and Elicia! Listen to the full podcast here. Jack Gassett ( @gadgetfactory ) is the creator of the open source FPGA  Papilio…

  • SparkFun Lunch and Learn: FPGAs for Makers, with Steve Grace

    Steve Grace, a Xilinx Engineer, gives a nice presentation at SparkFun on FPGA’s. While this presentation is not geared for beginners it does an amazing job of introducing all of the tools and techniques available with FPGA’s once you get to the intermediate level. Steve also does a very nice job of showing how your…

  • Flavia: the Free Logic Array

    Check out this amazing project from John Beetem. Make small Digital Logic designs without the heavyweight vendor tools. Flavia tool chain lets you make bit files for the Papilio One 250K with completely FLOSS software! Only CPLD sized designs are possible, but this is a boon for learning Digital Logic on ARM based boards like…

  • A CPLD Video Card With VGA And NTSC

    Here is a project to generate VGA and NTSC from a CPLD. The brains of the outfit is a $5, 100-pin CPLD from Xilinx. Apart from that, the rest of the components are a crystal, PLL, and an almost hilarious number of resistors for the R2R ladder. The one especially unique component is the 25.056815 MHz…

  • Intelligent LEDs – Using WS2812B LEDs with the Papilio.

      Hamster shows us how to use the latest and greatest WS2812B LEDs! The interface is pretty simple – the state of the bus has to be reset by holding the data signal low for 50us, followed with sending out 24 bits for each LED that is connected in the string. The ‘1’ bits are sent…
