8. Timer, GPIO, and 7-Segment Peripherals

Try these first

1. 1.

   What does GPIO stand for?

   Hint

   Think about what types of operations GPIO can perform.

2. 2.

   Name one application of timers.

   Hint

   Consider functions that require precise timing.

3. 3.

   What does the acronym AHB stand for?

   • Advanced High-performance Bus
   • Application High-speed Bus
   • Automated High-performance Bus

   Hint

   A bus standard for performance.

4. 4.

   True or False: A 7-segment display can only show numbers.

   • True
   • False

   Hint

   Think about the types of characters shown.

5. 5.

   Design an embedded system for a simple temperature display that uses a temperature sensor, GPIO for control, and a 7-segment display. Describe the interactions.

   Hint

   Think about how each component interacts in this setup.

6. 6.

   Explain how you would optimize GPIO usage in a project with multiple switches to minimize resource use while ensuring reliability.

   Hint

   Consider the resources available and how they can be efficiently utilized.
