HDMI Light V2
I was browsing HackADay when I came across an article called, “FPGA Ambilight Clone Packs a Ton of Features“. I immediately got excited and thought, “I hope we can port this to the Papilio.” When I opened the article I saw to my great delight that the project WAS done on the Papilio! Even better…

Robot Vision: Detecting Obstacles with FPGAs and line lasers
Check out this FPGA project that uses a camera module and laser to do obstacle and cliff detection. It’s Wishbone compatible so we should be easily able to import this project into DesignLab. Somewhere down the road, you’ll find that your almighty autonomous robot chassis is going to need some sensor feedback. Otherwise, that next…

Stepper
Hamster puts together a nice tutorial with code about driving a stepper motor with an FPGA. Driving a stepper motor using an external driver board is a bit tricky when using a microcontroller. With an FPGA it is a piece of cake! via hamsterworks.co.nz

Direct Digital Synthesis (DDS) Explained by [Bil Herd]
Bil Herd, the designer of the Commodore 128, talks about DDS (Direct Digital Synthesis) on a CPLD. There is some excellent information here that is very applicable to the Papilio FPGA. Maybe we can even adopt this project to DesignLab. “One of the acronyms you may hear thrown around is DDS which stands for Direct…

Hacking the OV7670 camera module (SCCB cheat sheet inside)
Here is a nice technical write-up of the OV7670 camera module that can be purchased on eBay for under $10. We have a Wing that lets you easily connect this camera to the Papilio. There are also VHDL code examples out there on Hamster’s Wiki page. All we need now is to make a DesignLab…

Hamster’s HDMI Input Project
Take a look at this forum project that Hamster is working on – HDMI input! Watch as he generates video pulls it into a Papilio, then converts it to VGA output. Very cool. 🙂 https://www.youtube.com/watch?v=AvHPYmEQb04 I hit a brick wall on this for a couple of days – it locked correctly but no HSYNC or…

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…
