Resources of Microcontrollers -- Using the Digital I/O Lines -- Using the Asynchronous Serial Interface -- Using the Synchronous Serial Interface SPI -- Using The I2C Bus -- Using the MCU Timers -- Interfacing to Analog Signals -- Using the Internal EEPROM Memory -- HC11 Development Board -- AVR Development Board -- 8051 Development Board -- Digital Voltmeter with RS232 Interface -- Simple RS485 Network with Microcontrollers -- PI Temperature Controller -- Fuzzy Logic Temperature Controller -- Remote Relay Controller over Telephone Lines.Stressing common characteristics and real applications of the most used microcontrollers, this practical guide provides readers with hands-on knowledge of how to implement three families of microcontrollers (HC11, AVR, and 8051). Unlike the rest of the ocean of literature on individual chips, Microcontrollers in Practice supplieS side-by-side comparisons and an overview that treats the systems as resources available for implementation. Packed with hundred of practical examples and exercises to foster mastery of concepts and details, the guide also includes several extended projects. By treating the less expensive 8-bit and RISC microcontrollers, this information-dense manual equips students and home-experimenters with the know-how to put these devices into operation.
