[Defcon 18] Image Writing Utility

[izzy4505]

For those of you that want a quick bitmap on your LCD, I wrote a quick utility tonight to do so. It's for Windows. http://www.musatcha.com/software/DC18BadgeImageWriter/

Re: Image Writing Utility

Your program's great! Good work.

I'm trying to make my images more permanent though, by replacing the stock images in the code, but I can't figure out how to flash it, using the CCS I get an autobaud failed. Any suggestions?

Thanks.

Re: Image Writing Utility

Sorry, I haven't dug into it yet beyond the basic comands in the built-in firmware. (Been too busy running around to talks! So much stuff I'm interested in this year...) Plenty of people in the Hardware Hacking Village have it all figured out though, so if you head up there I'm sure someone can give you some advice.

Very nice work. I was hoping someone would do something like this, since it helped lots of non-hardware people display cool stuff on the badge. Thanks!

The versions that were handed off to me in the HHV to host during con will be uploaded shortly. Been on my list of things to do. There is a very nice Python one that I know a lot of people used.

Re: Image Writing Utility

I wrote a ruby library, so it works in linux (haven't tested it in windows). It's based around writing text strings to the display, but it can take bitmaps as well.
not the best written or documented, but it's there.

FWIW during DC18 I also wrote a Python script to upload images to the badge, it's available here:

There's also some development notes and photos.
