  • How to Build an Arcade Obstacle Avoidance Game Using FPGA

    Hello FPGA innovators! Remember the arcade obstacle avoidance game where blocks of pixels fall on you and you steer clear of them moving left or right? Today’s project attempts to re engineer the same game using a VGA and FPGA. Here, a pseudo random code is used to generate obstacles that fall down and buttons…

  • Process VGA without Frame Buffers using FPGA

    Hello explorers of the FPGA Kingdom! Today’s project digs into the scope of FPGA as a tool that can replace conventional techniques further. VGA or video processing through conventional means requires a frame buffer which stores a block of data regarding pixel information in the system RAM for video display which is transferred to the…

  • How To Create You Own Design Displayed On A RGB LED Matrix With Your FPGA

    Today´s article presents a fantastic video tutorial about designing and building your own FPGA RGB LED matrix to display anything you want. Nowadays it´s pretty easy to buy an RGB LED matrix on internet, so you only need to connect your FPGA to it and build and implement your own design. So, you better follow…

  • Building a multi-peripheral controller with a GPAK4

      In today´s article the author describes a project developed by one of the prize winners. What prize winners? What prize at all? Ok, let´s rewind a little here. The author talks wonders about Silego´s GPAK chip and so those guys were very excited about the interest generated that they decided to give the author…

  • How To Control A LCD TFT Using Your FPGA (Or Someone Else´s)?

    Not long ago, we published some articles about controlling different kinds of displays, using your FPGA. On a VGA screen, on a small LCD screen, on a PSP LCD or even for the old, but nasty-analog-signaled NTSC system. And today, we share with you another great tutorial on how to control a LCD TFT, that…

  • How To Use Your FPGA To Display Things On A PSP Screen!

    Welcome back to the track of using your FPGA to display things. Today´s tutorial will teach you how to use the LCD screen of a PSP to display colour graphics from an FPGA. The main goal is to show three colour stripes on the screen but the author goes beyond that and adds a quick…

  • How to Display Video On A Screen With Only One Wire

    In today´s article we bring you a great tutorial about NTSC. For those who don´t know this, NTSC is another video standard, like VGA, very popular in the Americas and Eastern Asia. However, unlike VGA, NTSC only uses 1 signal wire! The principal behind that is quite complex. Thus, the example developed on the article…

  • How To Control What You See On A Screen in Two Hours and For Less Than $25!

    Imagine how cool it would be to control what appears on your screen and at a bargain price, just using your FPGA (yes! Your Papilio!) and some other easy-to-get components. All you need is read today´s article (and buy the tiny things of course). This how-to post is one of those which are written thinking…
