Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Design a simple application using an external interrupt to switch an LED on and off based on button presses in a C program. Include all relevant ISR logic.

💡 Hint: Use what we practiced with external interrupts.

Challenge 2 Hard

Given a timer interrupt scenario, write pseudocode to increment a counter every second. Discuss how you'd set the timer value based on a given oscillator frequency.

💡 Hint: Review the timer configuration we covered earlier.
