BASCOM-8051 and BASCOM-AVR are development environments built around a powerful BASIC compiler. Both are suited for project handling and program development for the 8051 family and its derivatives as well as for the AVR microcontrollers from Atmel. Это и многое другое вы найдете в книге BASCOM Programming of Microcontrollers with Ease. An Introduction by Program Examples (Claus Kuhnel)
