 +Hi Kris!
 +
 +Thank you very much for your Arduino asm introduction. I helped me a lot getting started.
 +
 +But then I tried to modify version 1.5.2 the same way, because according to the developer of the arduino eclipse plugin, this is the latest version compatible with the plugin. And I found out that you need to modify the file .../​hardware/​arduino/​avr/​platform.txt,​ too. So I thought, maybe you want to mention this in your introduction.
 +
 +in the "AVR compile patterns"​ section, adding the following solved the issue:
 +
 +## Compile S files
 +recipe.S.o.pattern="​{compiler.path}{compiler.c.cmd}"​ {compiler.S.flags} -mmcu={build.mcu} -DF_CPU={build.f_cpu} -D{software}={runtime.ide.version} {build.extra_flags} {includes} "​{source_file}"​ -o "​{object_file}"​
 +
 +Regards,
 +
 +Ralf
