AVR GCC Tutorial (WinAVR) Early before alpha Version 1. 00 This a Google translation for the famous German Wiki tutorial to be found in Inline Asm AVRGCC Inline Assembler Cookbook The most uptodate and detailed information on contraints for the avr can be found in the gcc manual. The x register is r27: r26, the y register is r29: r28, In this example an input value is read from a port and then an output value is written to the same port. If the compiler would have AVR Microcontrollers in Linux HOWTO 2 avr2, at90c8534, at86rf401, avr3, at43usb320, at43usb355, at76c711, avr4, avr5, at90can128, at94k, avr1.
