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…

SmartMatrix Animated GIF Player
Nice guide and library for playing animated GIFs on those RGB LED Array’s. We should be able to port this library to the ZPUino for use with the RGB LED Wing. This guide will show you how to add a microSD card to a Teensy 3.1 to play back animated GIFs on a 32×32…

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…

Retrocade ADC Demo project for PlanAhead
Papilio community member “Offroad” put together this nice little ADC demo for the RetroCade Synth. It puts the ADC chips through their paces and includes a PlanAhead project and source code. Anyway, one result is an ADC demo that got out of necessity a little more polished than planned. Controls LED…
