A little hint: you may use a SPI master and connect it in a clever manner to a RS232 TX engine. Maybe in between you must scale the ADCs values and translate the binary values to BCD or to ASCII... To get an idea what to do have a look there (its German): http://www.lothar-miller.de/s9y/categories/45-SPI-Master http://www.lothar-miller.de/s9y/archives/76-BCD-nach-ASCII.html http://www.lothar-miller.de/s9y/archives/93-Binaer-nach-ASCII-Hexadezimaldarstellung.html http://www.lothar-miller.de/s9y/archives/84-Binaer-nach-BCD-mit-1-Takt-pro-Stelle.html http://www.lothar-miller.de/s9y/categories/42-RS232 And to controll that all you will additionally need a FSM with a few states...
