Evaluation of CIE Marks:

It is suggested that at least a few simple programs to be executed by students using a simulation software or an 8051 microcontroller kit for better understanding of the course. This activity can be considered for the evaluation of 10 marks out of 40 CIE (Continuous Internal Evaluation) marks, reserved for the other activities.

Course outcomes:

At the end of the course, students will be able to:

• Explain the difference between Microprocessors & Microcontrollers, Architecture of 8051 Microcontroller, Interfacing of 8051 to external memory and Instruction set of 8051.
• Write 8051 Assembly level programs using 8051 instruction set. Explain the Interrupt system, operation of Timers/Counters and Serial port of 8051.
• Write 8051 Assembly language program to generate timings and waveforms using 8051 timers, to send & receive serial data using 8051 serial port and to generate an external interrupt using a switch.
• Write 8051 C programs to generate square wave on 8051 I/O port pin using interrupt and to send & receive serial data using 8051 serial port.
• Interface simple switches, simple LEDs, ADC 0804, LCD and Stepper Motor to 8051 using 8051 I/O ports.
