Challenge Problems
Push your limits with challenges.
Question 1
You have a timer with a 2 MHz clock frequency and a prescaler set to 4. Calculate the effective counting frequency and illustrate how it would impact a program counting events from a sensor.
💡 Hint: Remember to divide the base clock by the prescaler value.
Question 2
Scenario: Your microcontroller uses a prescaler of 16. If a timer is set to trigger an event every 1 second, determine the necessary base clock frequency.
💡 Hint: Think about how the prescaler impacts the time interval created by the timer.
