Embedded systems are more than part of human life. For instance, one cannot imagine life without mobile phones for personal communication. Its presence is virtually unavoidable in almost all facets of human endeavor. Nearly every electronic product designed today includes at least one microcontroller or other embedded processor. The course provides an in depth understanding of the architecture, pin description and Interfacing of the microcontroller with various input and output peripherals. The course includes the study of low end ,mid range and high end microcontrollers like 8051,PIC 16F and PIC 18F, AVR and ARM7. It also provides understanding of the serial communication protocols like I2C, SPI & CAN.
