Virtual Atmega2561 emulator

Emulator of Atmega2561 selected instructions written in C. Implemented instructions:

• LDI
• MOV
• FMUL
• FMULS
• FMULSU
• ELPM
• EIJMP
• EICALL
• IJMP
• RJMP
• LDD
• STD

Creating Unit Tests:

1. Create file with assembly instructions (file with .s extension) and put it into "/tests" folder
2. Follow the "make-test.sh" instructions written below
3. Follow the "compare.sh" instructions written below
4. Generated .hex files will showcase the functionality of the instructions.

Using the make-test.sh script:

1. Write "./make-test.sh -f filename" (filename without the extension)
2. Run the emulator ("./syko.exe" with apropriate arguments)
3. Copy the output file (file_data.bin) to "tests/binary data" and rename it to "name_out.bin" where name is the name of the test

Using the compare.sh script:

1. Run "./compare.sh" inside the folder "binary data", there will be created two output files: .dec i .hex

Using the test-all.sh script"

This script runs for each .s test file inside /tests/ It does the following:

1. Runs the make-test.sh script and creates adequate binary files
2. Runs syko.exe with arguments: 30 30 zeroPC
3. Copies output files (file_data.bin) to /tests/binary data with adequate name
4. Runs compare.sh script and creates comparison .hex and .dec files

To run it write ". ./test-all.sh" in terminal from "/tests/" folder
