3 cards from this section. Quick, good the night before a test.
What is a prescaler used for in timer configuration?
Think about how we manage the speed of the timer.
What does the auto-reload value determine in a timer?
It's about the maximum number the timer can reach.
What is the main purpose of a prescaler in a timer configuration?
Consider what influences the counting rate of the timer.
True or False: A timer can only be used without generating interrupts.
Think about how timers interact with their surrounding environment.
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.
Consider the clock cycles and how often you want the LED to update.
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?
Reflect on how these values correlate to the desired output frequency.
