This is a mixture of USBaspLoader (http://www.obdev.at/products/vusb/usbasploader.html) and LUFA (http://www.fourwalledcubicle.com/LUFA.php) The goal is to make a bootloader for the USB capable AVR microcontrollers, but: * using low speed USB instead of full speed * this is a requirement because the internal RC oscillator of the U4 series is only accurate enough for low speed USB devices, not full speed USB * compatible with AVRDUDE == Version 2012-07-10-18:30 == * Discovered that a 4048 byte file wouldn't verify properly, the writing works but reading had a tiny bug * Fixed the above bug == Version 2012-07-10-00:02 == * Fixed AVRDUDE errors == Version 2012-07-09-22:50 == * Put on GitHub for the first time, my first time putting something on GitHub * Works with AVRDUDE, able to write and verify 3376 bytes on an ATmega32U4, and the code behaved as expected * AVRDUDE will show "avrdude: error: usbasp_transmit: usb_control_msg: sending control message failed, win error: A device attached to the system is not functioning." all the time but the code does actually work * Compiles to about 2798 bytes, requires a 4K of bootloader space * The original LUFA makefile requires some modifications to work on my computer * Currently, only the signature bytes of the ATmega32U4 is implemented * Please help me fix the errors and make the code friendly for all USB capable AVR microcontrollers
