6 sample questions

Question 1.
What does GPIO stand for?
Show hintHide hint
Think about what type of signals these pins manage.
Question 2.
What is the main purpose of a timer in embedded systems?
Show hintHide hint
Recall the blinking LED example.
3Question 3.
What is the purpose of a timer interrupt?
- To initialize GPIO pins
- To generate periodic signals
- To reset the microcontroller
Show hintHide hint
Think about the blinking LED example.
4Question 4.
True or False: An ISR can perform extensive operations without impact.
- True
- False
Show hintHide hint
Remember the efficiency needed in handling ISRs.
Question 5.
Modify the provided LED blink program to create a feature that allows adjusting the blink rate through user input. Include the necessary code changes.
Show hintHide hint
Look at how you initialize the timer and consider using different timer intervals based on user input.
Question 6.
Create an ISR to manage two different GPIO pins connected to two different LEDs, toggling each LED at staggered intervals (e.g., LED1 every second, LED2 every half second).
Show hintHide hint
Don’t forget to structure your toggle logic clearly to prevent both LEDs from switching together.
