Bay Threat 2011 Badge

CharliePlexed LED badge

Source files Sub Version or WebSVN

Uses a 1 x 6 ISP socket, needs a kraken, AVR Dragon, AVR ISP etc. to program chips! Don't forget!!! . 6 pin 1×3 to 1×6 adapter or jumpers required.

Jameco stock this programmer http://www.jameco.com/webapp/wcs/stores/servlet/Product_10001_10001_2136420_-1 or this http://www.jameco.com/webapp/wcs/stores/servlet/Product_10001_10001_2136788_-1

See here for general programming details AVR_Programmer

code is in svn folder svn://svn.032.la:6699/032/BayThreat/code or use websvn above….

there are two projects, prebuilt hex files for flashing with programmer are in default folder.

note the ISP clock speed when you program them.. battery power is fine for programming

AVR Studio 4 and WinAVR to build projects

avr studio 4

winavr

<code> fuses are default settings for attiny2313 you can unset ckdiv/8 to make change the clock speed to 8Mhz make sure the speed for the ISP programmer is 125Khz for more time don't go lower than 1Mhz clock speed if using a dragon to program</code>
