This document describes a project to create a circuit that can quickly solve Karnaugh maps (K-maps), which are used to minimize logical expressions. The project team designed and simulated the circuit using Proteus and programmed a PIC18F4520 microcontroller with mikroC. They created a printed circuit board layout with DipTrace and assembled the working circuit. The circuit provides an accurate and fast way to minimize logical expressions but faces some issues like lack of a 3-state switch and needs further improvements like adding more variables and don't cares. The project helped improve the team's skills in programming, circuit implementation, and group work.
K-Map Solver Circuit
- 1. K-Map Solver Circuit PRESENTED BY • PRAKASH TIWARY • PAWAN BHARATI • NITHIN ABRAHAM • NISHANTH A
- 2. Why This Project? • K-Map is a method of minimizing logical expressions. • As Electronics students, we come across K-Map at different occasion. • K-Map solving is time consuming. • Needed a fast way to solve K-Map. • Realizing a circuit for this was the better option
- 3. How did we realize this Project? • First of all we did a simulation of our proposed circuit using Proteus. • We used PIC18F4520 microcontroller for this project. • Programming for PIC was done by mikroC. • PICkit2 programmer was used to burn the hex file. • When we found that our circuit is working, we used Dip trace to design our PCB Layout. • And finally we assembled all components using soldering.
- 5. Technical Details: Block Diagram
- 7. Difficulties Faced •We did not find switch which has 3 states so we excluded don’t cares. •Shock Problem •LCD brightness Problem
- 9. Usefulness of Circuit • Accurate minimizing of expressions • Time saving • User-friendly • End product used as Lab-Kit
- 10. Further Improvement • Increasing number of Variable which is 4 now. • Include don’t cares • Making circuit board more compact • Including expression for POS • Reducing cost of Kit • Reducing length of code to improve run time lag.
- 11. Conclusion • We have completed our project on K-MAP SOLVER CIRCUIT. The circuit works as expected and finds the reduced expression very fast. By completing this project we have improved our skills in programming and implementing circuits. It has also improved our ability to work as a group and to face problems together. We were able to rectify problems we faced during the implementation of the project. We are extremely satisfied that we were able to program, design and implement a circuit from scratch. We take this opportunity to thank all who had helped us to complete this project.
