            <h1>YASAB - Yet another simple AVR Bootloader</h1>
<p>YASAB ist ein einfacher AVR Bootloader, geschrieben in C für die <a href="http://www.nongnu.org/avr-libc/">AVR libc</a>. Von einem PC-Programm aus werden die Daten über ein simples Protokoll per UART an den AVR gesendet. Wurde der Bootloader für den ATmega168, 128x oder 256x kompiliert, wird sowohl auf USART0 als auch auf USART1 Daten erwartet. <a href="https://github.com/xythobuz/yasab">Der aktuellste Quellcode findet sich stets im Github Repository</a>. Die Upload Software kann einfach statt avrdude oder ähnlichem in makefiles eingebaut werden.</p>
<p>Außerdem implementiert meine <a href="https://github.com/xythobuz/xyControl/tree/master/tools/xyCopter">Android App xyCopter</a> einen YASAB kompatiblen Uploader über <a href="/bluetooth.html">Bluetooth</a>.</p>
