Tutorial — Practice 9: Integrator project

What you will build

Integrate GPIO, timers, ADC, or serial in your own project with simulation and demo.

Steps in this tutorial

1. 1. Choose your integrator system
2. 2. Pseudocode and flowchart
3. 3. Modular assembly code
4. 4. Proteus simulation with evidence
5. 5. Hardware demo and report

1. 1

   Choose your integrator system

   Course options: traffic light, level control, station with LCD/keyboard, etc. Must be feasible on PIC18F4550 and combine at least 3 modules (GPIO, timer, ADC, UART, PWM, motor…).

2. 2

   Pseudocode and flowchart

   Before .ASM: define inputs, outputs, states, and main loop. Include ovals, rectangles, diamonds, and ISRs if any. Your instructor evaluates design before code.

3. 3

   Modular assembly code

   Split into files or sections: `init`, `isr`, `lcd`, `adc`, `main`. Reuse routines from earlier practices adapting pins. Comment each routine with purpose and registers used.

4. 4

   Proteus simulation with evidence

   Build the full schematic. Capture each mode or sequence. Note which inputs you simulated (buttons, pot, serial).

5. 5

   Hardware demo and report

   Demo on hardware (if applicable) and orally explain program flow. Report: objective, schematic, pseudocode, commented listing, tests, and conclusions.

Starting point

Use the final partial-style project guide and sample projects as reference. Pick a system that combines at least three course modules.

Deliverables

1. Pseudocode and flowchart (paper or digital).
2. Modular MPASM assembly code.
3. Proteus simulation with screenshots.
4. Hardware demo and oral explanation.
