How to use MiniIDE and SIMHC12?

It's simply used by 'help' menu.These steps here are only for simulations.

You have to read my module before you proceed to the next steps.


MiniIDE

1.   Open MGTEK MiniIDE. Click on 'File' and 'New'.Write your program with assembly language here. You must start with tab once. Your program should begin with 'org' which is the locations of your instructions will be stored.

 2.     After finished typing your program, save your file with extension of *.asm.

3. Go to menu ‘Build’-click on ‘Set Project File’.

 4. Again, ‘Build’ menu and click ‘Build’ the file.

This 'Build' is actually an assembler. It will automatically generate list file and machine language with *.lst file and *.s19 file correspondingly. You can see the file it is generated inside the file you save your program.

Click on file with extension of *.lst and *.s19 file. s19 file is a machine code that is already translated by the assembler.

SIMHC12

Assume this simulator as CPU12 complete with memory space. You have to load the machine language file because CPU can only understand the machine code, not the assembly language or else.

1. Load your machine file (*.s19) to this simulator with choose File menu and click on Load. 

2. Observe that the machine language is already in the memory.

3. Set your PC to the location where your program is stored. In this case, your program is starting at address $800.

4. Use step to observe the result of the instruction step-by-step.

First 'step execute' means that the first instruction is executed. First instruction is LDD #$983E; the data $983E is loaded into double accumulator D. PC is pointed to the next instruction that is INY.

After click on 'step' again, we realise that the index register y increase to 1 from 0 value.

Wish you all the best.
