Embedded Systems

Course Objective:

This course introduces students to embedded system architecture, microcontrollers, and real-time operating systems. Students learn programming in C and Python, peripheral interfacing, and communication protocols to design and implement embedded applications for real-world automation systems.

Embedded Hardware Architecture: CISC Architecture: Introduction to MCS51 Family, 8051 Microcontroller – Architecture, Timers, Interrupts, Serial Data Communication.

RISC Architecture: Overview of PIC16F487x family, PIC16F877A – Architecture, Timers, Interrupts, Serial ports.

Activity: Simulate and compare basic programs (timers/interrupts) on 8051 and PIC microcontrollers.

Arm And Embedded Software Development Tools: Introduction to ARM – LPC4088 Architecture. Software Development Tools: IDE Tools, ISP Tools, ARM Development Tools.

Activity: Develop and debug a simple embedded application using an ARM-based IDE and development tools.

Wired Communication Interfaces: Wired Communication Protocols: Serial – RS232, RS485, I2C, SPI, USB; Parallel – IEEE 488.

Activity: Implement serial communication (UART/I2C/SPI) between a microcontroller and an external device.

Wireless Communication Interfaces: Wireless Communication Protocols: Bluetooth Classic, BLE, IEEE 802.15.4, Zigbee, IEEE 802.11, LoRaWAN.

Activity: Demonstrate wireless data transmission using a module(e.g., Bluetooth/Zigbee/Wi-Fi).

Real-Time Operating System: Operating System Basics: The Kernel and its subsystems, Kernel Space and User Space. Types and Functions of RTOS: Task, Process and Threads, Interrupt Handling, Multiprocessing and Multitasking, Task Scheduling. Comparative study of various RTOSs.

Activity:Simulate task scheduling and interrupt handling using an RTOS environment.

Embedded Programming and Peripheral Interfacing: Embedded C and Python Programming for Embedded Applications. Peripheral Interfacing: Input and Output Devices, ADC, DAC, PWM Generation, Sensor Interface.

Activity: Develop an embedded application interfacing sensors/actuators using open source tool.

Weightage: Continuous Assessment: 40%, End Semester Examinations: 60%

Assessment Methodology: Quiz (5%), Assignments (25%), Review of GATE/ESE Questions, Internal Examinations (50%)
