* Sjá: [[Hello world rafrásir]]
=== serial output ===
Einföld rafrás sem notar [[RS-232]] (serial) staðalinn til að senda 8 bita [[ASCII]] textastrenginn "Hello World!" aftur og aftur á 9600 bit per sekúndu.
 
Tvær útgáfur af forritskóðanum eru hér - annars vegar skrifað í smalamáli, og hinsvegar í C.
 
* [http://fab.cba.mit.edu/about/fab/hello/serial/hello.serial.45.cad hello.serial.45.cad] - rafrás, teikning
* [http://fab.cba.mit.edu/about/fab/hello/serial/hello.serial.45.asm hello.serial.45.asm] - smalamálskóði
* [http://fab.cba.mit.edu/about/fab/hello/serial/hello.serial.45.hex hello.serial.45.hex] - vélamál (vistþýtt)
* [http://fab.cba.mit.edu/about/fab/hello/serial/hello.serial.45.c hello.serial.45.c] - C kóði
* [http://fab.cba.mit.edu/about/fab/hello/serial/makefile makefile] - Make skrá fyrir C kóða
 
=== serial echo ===
Ögn flóknari rafrás sem notar [[RS-232]] (serial) staðalinn til að hlusta eftir textastrengjum og skrifa þá um leið til baka á 9600 bit per sekúndu. Svona rásir eru kallaðar "echo" rásir - gera ekkert nema endurvarpa gögnum.
 
Aftur, bæði smalamáls- og C forrit, en nú er líka útgáfa fyrir ATTiny44.
 
* [http://fab.cba.mit.edu/about/fab/hello/echo/hello.echo.45.cad hello.echo.45.cad] - rafrás, teikning, ATTiny45

* [http://fab.cba.mit.edu/about/fab/hello/echo/makefile makefile] - Make skrá fyrir C kóða, ATTiny45
 
* [http://fab.cba.mit.edu/about/fab/hello/echo/hello.echo.44.cad hello.echo.44.cad] - rafrás, teikning, ATTiny44
* [http://fab.cba.mit.edu/about/fab/hello/echo/hello.echo.44.asm hello.echo.44.asm] - smalamálskóði, ATTiny44
 
=== Takki ===
