Step 2 of 11
Create project and .ASM file
Goal
Have an MPLAB project for PIC18F4550 with file guia-interrupciones.asm ready to edit.
You do not write interrupt code yet. Only set up the environment like the ports guide: project, device PIC18F4550, and .ASM file under Source Files.
Follow these steps
- MPLAB: File → New Project (or reuse a course project) → device PIC18F4550 → MPASM or XC8 per your lab.
- Create Source Files → New → Assembly File → name
guia-interrupciones.asm. - Leave the file empty or with comment
; Interrupts guide. - Save all. Do not build yet.
Checklist before you continue
- MPLAB project created for PIC18F4550.
- `guia-interrupciones.asm` exists under Source Files.
- File saved on disk.
Tip: You can copy the ports guide project and rename the `.ASM` — but use a file dedicated to interrupts.
