12.4.2. Steps Involved

Try these first

1. 1.

   What is the purpose of initialization in an embedded system?

   Hint

   Remember, it's the first step!

2. 2.

   What function do we generally use to acquire data from a sensor?

   Hint

   Think about what we do to get readings from our devices.

3. 3.

   What function is used to initialize the LCD?

   • lcd_start()
   • lcd_init()
   • lcd_config()

   Hint

   Think about the naming conventions used for initialization.

4. 4.

   True or False: Data is acquired from a sensor only once and used indefinitely.

   • True
   • False

   Hint

   Consider real-time applications.

5. 5.

   Design a simple embedded application that uses a temperature sensor and an LCD. Outline how to implement each of the steps: initialization, data acquisition, processing, and displaying the output.

   Hint

   Break down the problem by focusing on one step at a time.

6. 6.

   If your application requires ultra-low power consumption, how would you adjust your data acquisition strategy?

   Hint

   Consider how often you really need those readings and how to balance accuracy with energy efficiency.
