Serjtag is doing exactly that with the FTDI 232 chip on the Arduino, in order to reflash the bootloader of the ATMega: http://www.geocities.jp/arduino_diecimila/bootloader/index_en.html -- Benjamin Henrion <bhenrion at ffii.org> FFII Brussels - +32-484-566109 - +32-2-4148403 "In July 2005, after several failed attempts to legalise software patents in Europe, the patent establishment changed its strategy. Instead of explicitly seeking to sanction the patentability of software, they are now seeking to create a central European patent court, which would establish and enforce patentability rules in their favor, without any possibility of correction by competing courts or democratically elected legislators." ------------------------------------------------------------------------------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.
