We use the Atmel ATmega164 as a representative sampleoftheAVRline.Theknowledgeyougainonthismicrocontrollercanbeeasilytranslatedto everyothermicrocontrollerintheAVRline.Insucceedingchapters,wecoverthemainsubsystems aboardthemicrocontroller,providingashorttheorysectionfollowedbyadescriptionoftherelated microcontrollersubsystemwithaccompanyingsoftwareforthesubsystem.Wethenprovideadvanced examples exercising some of the features discussed. In all examples, we use the C programming language.The code provided can be readily adapted to the wide variety of compilers available for the Atmel AVR microcontroller line. We also include a chapter describing how to interface the microcontroller to a wide variety of input and output devices. The book concludes with several detailedsystemleveldesignexamplesemployingtheAtmelAVRmicrocontroller.
