Show hintHide hint
Remember the first step before using hardware.
Question 2.
Give an example of a control function.
Show hintHide hint
Think about controlling the state of GPIO pins.
3Question 3.
What is the purpose of initialization functions in APIs?
- They manage interrupts
- They set up hardware
- They control peripherals
Show hintHide hint
Think about the first step to take before using a peripheral.
4Question 4.
True or False: Control functions can only set hardware to a default state.
- True
- False
Show hintHide hint
Consider the actions you can perform with control functions.
Question 5.
Design an embedded API structure that integrates all four function types (initialization, control, status, and interrupt handling) for a new temperature sensor.
Show hintHide hint
Consider how each function interacts for a complete input-output cycle.
Question 6.
Explain how to use the interrupt handling function in a system that receives live updates from a sensor, ensuring that no data is missed during processing.
Show hintHide hint
Think of how interrupts help maintain responsiveness while processing.
