8.2. Timer Peripherals

Try these first

1. 1.

   What does a timer do?

   Hint

   Think about timers and their role in measuring duration.

2. 2.

   What is a prescaler?

   Hint

   What helps modify the timer's counting rate?

3. 3.

   What type of timer generates periodic interrupts?

   • PWM Timer
   • Basic Timer
   • Capture/Compare Timer

   Hint

   Think about what each timer type primarily accomplishes.

4. 4.

   True or False: Capture/compare timers can be used to measure frequency.

   • True
   • False

   Hint

   Consider the functions of capture timers.

5. 5.

   Design a simple embedded system that uses timer peripherals to control LED blink rates. Detail how the timer configuration would be set up.

   Hint

   Consider how you would utilize a timer to manage timed actions in your design.

6. 6.

   Develop a program that uses a PWM timer to adjust the brightness of an LED. Explain how you will implement varying pulse widths.

   Hint

   How does changing the width of the pulse affect the brightness?
