Logic analyzer for signal debugging in Embedded C - Mini Project: Build & Apply

Logic analyzer for signal debugging

📖 Scenario: You are working with a microcontroller to debug digital signals from sensors. You want to capture the signal states over time to analyze their behavior.

🎯 Goal: Build a simple logic analyzer program that stores signal states in an array and prints the captured data for debugging.

📋 What You'll Learn

Create an array to store signal states

Define the number of samples to capture

Write a loop to simulate capturing signal states

Print the captured signal states

💡 Why This Matters

🌍 Real World

Logic analyzers help engineers see how digital signals change over time, which is important when fixing hardware or software problems.

💼 Career

Embedded developers and hardware engineers use logic analyzers to debug circuits and ensure devices work correctly.

1

Create an array to store signal states

Create an integer array called signal_data with size 10 to store signal states.

Embedded C

# Your code here

Need a hint?

Use int signal_data[10]; to declare the array.

2

Define the number of samples to capture

Create an integer variable called num_samples and set it to 10.

Embedded C

int signal_data[10];
# Your code here

Need a hint?

Use int num_samples = 10; to set the number of samples.

3

Capture signal states in a loop

Write a for loop using int i from 0 to num_samples - 1. Inside the loop, set signal_data[i] to i % 2 to simulate signal states alternating between 0 and 1.

Embedded C

int signal_data[10];
int num_samples = 10;
# Your code here

Need a hint?

Use a for loop and assign signal_data[i] = i % 2; inside it.

4

Print the captured signal states

Write a for loop using int i from 0 to num_samples - 1. Inside the loop, use printf to print signal_data[i] followed by a space. After the loop, print a newline using printf("\n").

Embedded C

int signal_data[10];
int num_samples = 10;

for (int i = 0; i < num_samples; i++) {
    signal_data[i] = i % 2;
}
# Your code here

Need a hint?

Use printf("%d ", signal_data[i]); inside the loop and printf("\n"); after the loop.
