8.6.1. Timer and GPIO Interaction

Try these first

1. 1.

   What is a timer used for in embedded systems?

   Hint

   Remember the basic function of timers.

2. 2.

   What does GPIO stand for?

   Hint

   Think about the I/O functionality.

3. 3.

   What is one primary function of a timer in an embedded system?

   • To store data
   • To measure time
   • To transmit data

   Hint

   Think about the role of timing in processes.

4. 4.

   True or False: GPIO pins can only be used for output.

   • True
   • False

   Hint

   Recall how GPIO pins are configured.

5. 5.

   Design a simple electronic game where timers and GPIO interact. Explain the components and functionality.

   Hint

   Think of game mechanics that rely on timing and user interaction.

6. 6.

   You have a timer set to trigger an event every 5 seconds and GPIO pins controlling LED lights. Explain how you would implement a blinking light based on the timer.

   Hint

   Think about using the timer interrupts to control GPIO states.
