Tutorial catalog

Interactive tutorials do not replace theory: you do them after reading the pages that prepare you, in study path order.

These tutorials are not separate from the course: they appear on the study path right after the theory that prepares you. Use this catalog to find a specific lab or review; to learn from scratch, follow the study path.

Practical guides (step by step)

Multi-page mini-courses (Astro/Expo style). Inserted on the path before the related lab.

Using GPIO ports 11 steps
Step-by-step tutorial: from creating the MPLAB project to simulating an LED controlled by a button — one verifiable action per step.
ALU operations in assembly 5 steps
Add, subtract, multiply, logic, and rotates with operands in WREG. Direct prep for Practice 1.
PIC18 interrupts 11 steps
Step-by-step guide: from polling to a Timer0 ISR that blinks an LED without blocking the main loop — one verifiable action per step.
