11.3.5. I2C/SPI

Try these first

1. 1.

   What does I2C stand for?

   Hint

   Think about how devices communicate using this protocol.

2. 2.

   Name one wire used in I2C.

   Hint

   Remember the data and timing lines.

3. 3.

   What does I2C stand for?

   • Inter-Integrated Circuit
   • Integrated Communication Circuit
   • Internal Circuit Communication

   Hint

   Think about the nature of the protocol's application.

4. 4.

   Which of the following is a feature of SPI?

   • True
   • False

   Hint

   Recall how many wires SPI generally uses.

5. 5.

   Design a simple embedded system that utilizes both I2C and SPI for different purposes. Explain your choice of peripherals for each protocol.

   Hint

   Consider the speed, complexity, and number of devices when making your choices.

6. 6.

   Write a detailed initialization sequence for an SPI device using CMSIS. Include comments explaining each step.

   Hint

   Refer to CMSIS library functions and device datasheets for proper initialization sequences.
