12.2.4. Peripheral Driver APIs

Try these first

1. 1.

   What does the term 'Peripheral Driver API' refer to?

   Hint

   Think about what APIs do in general.

2. 2.

   What function initializes a UART for use?

   Hint

   Consider what needs to be done first before sending data.

3. 3.

   What is a Peripheral Driver API used for?

   • To program software applications
   • To interact with hardware peripherals
   • To compile code

   Hint

   Focus on what interaction takes place between software and hardware.

4. 4.

   True or False: Control functions in Peripheral Driver APIs allow us to check the status of a peripheral.

   • True
   • False

   Hint

   Remember the distinction between managing and querying.

5. 5.

   Design a Peripheral Driver API for a simple temperature sensor. Outline the structure and the types of functions it would include.

   Hint

   Think about what functionalities you would need from a temperature sensor.

6. 6.

   How would you implement an interrupt for a button press in your Peripheral Driver API? Describe the flow.

   Hint

   Consider the sequence of actions when a button is pressed and how the system should respond.
