Challenge Problems
Push your limits with challenges.
Question 1
Modify the provided LED blink program to create a feature that allows adjusting the blink rate through user input. Include the necessary code changes.
💡 Hint: Look at how you initialize the timer and consider using different timer intervals based on user input.
Question 2
Create an ISR to manage two different GPIO pins connected to two different LEDs, toggling each LED at staggered intervals (e.g., LED1 every second, LED2 every half second).
💡 Hint: Don’t forget to structure your toggle logic clearly to prevent both LEDs from switching together.
