GUJARAT TECHNOLOGICAL UNIVERSITY (GTU)

Competency-focused Outcome-based Green Curriculum-2021 (COGC-2021)

Semester - V

Course Title: Embedded System & Microcontroller Application (Course Code: 4351102)

1. RATIONALE

The knowledge of embedded system and microcontrollers is essential in the field of electronics as the world is migrating towards automation rapidly in every field. By learning this course students can develop their own embedded system using microcontrollers which is application specific to solve given real time problems. Thus this course is an important course for students who want to work in the automation sector of the electronic industry.

2. COMPETENCY

The purpose of this course is to help the student to attain the following industry identified competency through various teaching learning experiences:

Competency: Develop embedded systems for microcontroller application.

3. COURSE OUTCOMES (COs)

The theory should be taught and practical should be carried out in such a manner that students are able to acquire different learning outcomes in cognitive, psychomotor and affective domain to demonstrate following course outcomes.

1. Select appropriate microcontroller for given embedded system.
2. Explain architecture and working of AVR microcontroller.
3. Write and execute embedded C program for given application.
4. Interface AVR microcontroller with hardware for given embedded system.
5. Develop small embedded system using AVR microcontroller.

4. TEACHING AND EXAMINATION SCHEME

Note: Out of 30 marks under the theory CA, 10 marks are for assessment of the micro-project to facilitate integration of COs and the remaining 20 marks is the average of 2 tests to be taken during the semester for the assessing the attainment of the cognitive domain UOs required for the attainment of the COs.

Legends: L - Lecture; T - Tutorial/Teacher Guided Theory Practice; P - Practical; C - Credit; CA - Continuous Assessment; ESE - End Semester Examination.

5. SUGGESTED PRACTICAL EXERCISES

The following practical outcomes (PrOs) are the subcomponents of the COs. These PrOs need to be attained to achieve the COs.

Notes

1. More Practical Exercises can be designed and offered by the respective course teacher to develop the industry relevant skills/outcomes to match the COs. The above table is only a suggestive list.
2. The following are some sample 'Process' and 'Product' related skills (more may be added/deleted depending on the course) that occur in the above listed Practical Exercises of this course required which are embedded in the COs and ultimately the competency.

6. MAJOR EQUIPMENT/INSTRUMENTS REQUIRED

1. Computer
2. Projector
3. Trainer Kit

List of Software

1. Free Simulation tools

7. AFFECTIVE DOMAIN OUTCOMES

The following sample Affective Domain Outcomes (ADOs) are embedded in many of the above-mentioned COs and PrOs. More could be added to fulfill the development of this competency.

1. Work as a leader/a team member.
2. Follow ethical practices.

The ADOs are best developed through the laboratory/field-based exercises. Moreover, the level of achievement of the ADOs according to Krathwohl's 'Affective Domain Taxonomy' should gradually increase as planned below:

1. 'Valuing Level' in 1st year
2. 'Organization Level' in 2nd year
3. 'Characterization Level' in 3rd year

8. UNDERPINNING THEORY

Only the major Underpinning Theory is formulated as higher level UOs of Revised Bloom's taxonomy in order development of the COs and competency is not missed out by the students and teachers. If required, more such higher level UOs could be included by the course teacher to focus on attainment of COs and competency.

9. SUGGESTED SPECIFICATION TABLE FOR QUESTIONPAPER DESIGN

Legends: R=Remember, U=Understand, A=Apply and above (Revised Bloom's taxonomy)

10. SUGGESTED STUDENT ACTIVITIES

Other than the laboratory learning, following are the suggested student-related co-curricular activities which can be undertaken to accelerate the attainment of the various outcomes in this course. Students should conduct following activities in group and prepare reports of each activity.

1. Prepare journals based on practical performed in laboratory
2. Prepare chart to represent the block diagram of different interfacing chips
3. Develop a practical application using ATMega32 Microcontroller
4. Prepare General purpose board with all ports available as connector
5. Prepare/Download a dynamic animation to illustrate the following:
   • Timer operation
   • Two Wire serial Interface (I2C)
   • MAX 7221 Interfacing
   • DC Motor Interfacing

11. SUGGESTED SPECIAL INSTRUCTIONAL STRATEGIES (if any)

These are sample strategies, which the teacher can use to accelerate the attainment of the various outcomes in this course:

1. Massive open online courses (MOOCs) may be used to teach various topics/sub topics
2. Guide student(s) in undertaking micro-projects
3. Some of the topics/sub-topics is relatively simple and very easy to the students for self-learning, but to be assessed using different assessment methods
4. With respect to section No.09, teachers need to ensure to create opportunities and provisions for co-curricular activities
5. Guide students for using latest Technical Magazine
6. Arrange visit to relevant industry
7. Show video lectures on Microcontroller Applications with help of internet
8. Programming practices on simulators (free downloadable)

12. SUGGESTED MICRO-PROJECTS

Only one micro-project is planned to be undertaken by a student that needs to be assigned to him/her in the beginning of the semester. In the first four semesters, the micro-project is group-based. However, in the fifth and sixth semesters, it should be preferably be individually undertaken to build up the skill and confidence in every student to become

problem solver so that s/he contributes to the projects of the industry. In special situations where groups have to be formed for micro-projects, the number of students in the group should not exceed three.

The micro-project could be industry application based, internet-based, workshop-based, laboratory-based or field-based. Each micro-project should encompass two or more COs which are in fact, an integration of PrOs, UOs and ADOs. Each student will have to maintain dated work diary consisting of individual contribution in the project work and give a seminar presentation of it before submission. The total duration of the micro-project should not be less than 16 (sixteen) student engagement hours during the course. The student ought to submit micro-project by the end of the semester to develop the industry-oriented COs.

A suggestive list of micro-projects is given here. This has to match the competency and the COs. Similar micro-projects could be added by the concerned course teacher.

1. Prepare Specification Table for AVR microcontroller family
2. Design a chart of ATMega32 Architecture
