  • New Tutorial – PWM outputs on Papilio FPGA

    In this tutorial you will learn how to use the PWM outputs of your Papilio FPGA board. For this particular step-by-step article, we have connected a button LED Wing to Wing slot AL. Basically you will be able to write a sketch that uses a PWM on any pin. We have only used 6 pins…

  • You´ve got the Power in your hand or, better said, in the Wheel of your mouse!

      https://youtu.be/cWH4kVPpL3Y Today´s article will teach you how to build a system to control big power. You can use it to manage a simple light bulb or a 0.5 kW motor without having to change a single line of code. The key of this design is the implementation of a widely-used jellybean wheel from a…

  • Program your FPGAs and CPLDs at zero cost with the BBB

    Today, we present a thorough tutorial on how to take advantage of the BeagleBone Black to implement programmable logic. This is a very easy procedure. It is browser-based, and you just need to drag and drop your programming files into the beagle, wait a few seconds…and done! That simple! The recommendation is to start with…

  • New Tutorial – Draw a circuit with Commodore 64 SID audio chip!

    In our ongoing quest to make using an FPGA as simple as drawing up a schematic we have a new tutorial ready. Using the Papilio Schematic Library you can draw up a circuit that has a Commodore 64 SID chip connected to a ZPUino Soft Processor, without learning any VHDL or Verilog! Just drag and…

  • Accelerometer Tilt Sensing On Altera DE0 Nano FPGA

    We found a great tutorial for using an accelerometer’s tilt data on an FPGA over at Pyro Electro. In this particular project, they’re using an Altera DE0-Nano board (and using the built-in accelerometer), a breadboard, the DE0-Nano Development Suite software, (32x) 100 mega resistors, (32x) green LEDs, and jumper wires. Check out the video above,…

  • Tutorial: Adding Two Extra Serial Ports To ZPUino

    Hey there folks! There have been several questions on the forums recently about how to add some additional serial ports on the ZPUino, so Jack has put up a great tutorial over on the ZPUino documentation regarding this subject. I popped the video in above so you can take a look-see! Here are your resources:…

  • High Speed Data Transfer Between Two Papilios

    Mike Field (hamster) of Hamsterworks has written a new tutorial on how to achieve a high-speed data transfer between two Papilio One 250k boards.  The goal of the project was to achieve data transfer at 400 mbps, and Mike wound up exceeding the target by a pretty good margin. From Mike’s project description, The aim…

  • How To: Using State Machines With FPGAs

    We found a great article by Adam Taylor (Principal Engineer, EADS Astrium) that illustrates in detail how to implement state machines with your FPGA board. For anyone that is interested, Mr. Taylor provides a comprehensive tutorial on using the two classes of state machines (Moore and Mealy), state machine definitions, state machine encoding, and much…
