SVN Repo @ rev49 - full emulation with the teensy++ and miniSD see here: Forum Announcement <-Follow progress there

Thursday, January 27, 2011


SVN repository online:


Feel free to check it out or "check it out" using your favorite svn client.

Teensy++ uses lufa (older 11-09) and avr studio 4
EVK1104 uses avr32 framework 1.6 and AVR32 studio
Custom Board uses avr32 framework 1.7 and AVR32 studio

Want to join the development? Let me know in the forum
Want to know more about the project checkout the site here

Please bear with me on the state of the svn, the teensy++ code will be rewritten with the current lufa code, plus cleaned up.

Have ignored this blog for a while, sorry folks.

The board went together without any disasters, My first designed and soldered board with a qfp144 cpu and I nailed it :) - a couple issues, but hey its beta-ish .

Wrote a bunch of new code, most of which is to conform to the different hardware.
screen:   was vga(320x240) now 4x20 lcd
buttons: was qtouch controlled now 4 tactile switches
Still need to work more with the finer points of the iso to cd emulation. It works but theres allot of room for  growth to fine tune the code and include some of the ignored routines.

Change the way I handle iso files. Before I couldn't support fragmented files, Now can handle fragmented files with only about a 8% loss in speed. Plus with the new setup will easily be able to handle split iso's that are over 4gig's in size( get around the fat32 size limitation).

Looking into svn hosting with, have started the setup process.
in the mean time check out the forum

Tracking waisted time on cd's

Over at the official site the next 60 days of wasted time playing with cd's will be recored. Every time a cd is looked for plus the load time for each cd's.

This way once the production unit is up and running then will start to compare times - I bet I'll even be surprised at the saved time.

Well I have time on my hands...

Nothing to do but wait for the board..... Started a full revamp of Hope to have alot more info hosted there as this project continues.

ordering board this weekend

The layout looks good will be ordering my first prototype board this weekend. If everything goes as planned will be assembling the fist avr32 high speed cd emulator within a few weeks. The boards from takes a few weeks to process. Then some firmware tweak and ill be up and running!

Current progress

Ordering the parts for my first fully assembled prototype. Ended up deciding on a 4x20 lcd screen, sd card (iso storage) interface, 4 pushbutton interface input, AVR32 cpu (for the high speed interface), including a misc assortment of pcb parts. As soon as the parts come in i'm going to compare placement with the eagle pcb printout. If everything lays out correctly then I'll get the board printed through

Ordered a decent soldering station and all the misc items - good magnifying desk lamp, solder wick, solder paste, couple kinds of fluxes, etc... Been practicing soldering qfp packages. Its easer than I thought. The qfp144 pin package of the AVR32 scared me at first. Been mostly working with through hole. But hey now I know I can assemble the boards.

Currently parts and pcb cost for 1 off runs are about $120, but once It's all working I'll start making them in bigger batches to bring cost down.

Also tossing around the idea of bringing out the unused io pins for a cheap devel kit working with Atmels AVR32 framework - just modified to work with the lcd and switches the rest of the layout is based off of the EVK1104 (avr32, sd interface, usb hs, jtag, reset / gp - DFU Bootloader). Once the project is done, ill be deciding how far I want to explorer this route. If interested drop me an email:

Till next time, thanks for your interest...
