A PC Program sends the data to be programmed with a simple protocol via UART to the AVR. If the bootloader was compiled for the ATmega168, 128x or 256x, it will listen on both USART0 and USART1 for serial communication attempts. <a href="https://github.com/xythobuz/yasab">The most recent source code can be found in the Github Repository</a>. The Upload software can easily be used in place of avrdude in makefiles.</p> <p>Another YASAB compatible Uploader implementation is in my <a href="https://github.com/xythobuz/xyControl/tree/master/tools/xyCopter">xyCopter Android App</a>, using <a href="/bluetooth.html">Bluetooth</a>.</p> <pre> yasab /dev/tty.usbserial-A100QOUE test.hex q Hex File Path : test.hex Minimum Address : 0x0 Maximum Address : 0x61E2 Data payload : 25068 bytes Pinging bootloader...
