Challenge Problems
Push your limits with challenges.
Question 1
Design a timer system for a microcontroller that will turn on an LED every 2 seconds. Write the necessary configurations and explain how each part works.
💡 Hint: Consider the clock cycles and how often you want the LED to update.
Question 2
How would you modify a timer configuration to switch an application from a 1-second interval to a 10-second interval using the same timer? What changes would you make to the prescaler and the auto-reload register?
💡 Hint: Reflect on how these values correlate to the desired output frequency.
