7.1. Introduction to AHB UART Peripheral

Try these first

1. 1.

   What does UART stand for?

   Hint

   Think about communication protocols.

2. 2.

   What are the two main lines used in UART?

   Hint

   Recall the purpose of each line in communication.

3. 3.

   What does UART stand for?

   • Universal Asynchronous Receiver-Transmitter
   • Universal Asynchronous Radio-Transmitter
   • Used Asynchronous Transfer

   Hint

   Look for what allows devices to communicate serially.

4. 4.

   True or False: The AHB bus allows for synchronous communication.

   • True
   • False

   Hint

   Think about the definitions of synchronous vs asynchronous.

5. 5.

   You are tasked with configuring a UART peripheral to communicate with a GPS module that requires a baud rate of 9600. Describe the process and considerations taken.

   Hint

   Remember the relationship between baud rate and clock frequency.

6. 6.

   A student is creating an embedded system with UART to control an external device, but they experience data loss. What could be the potential reasons for this issue and solutions to address them?

   Hint

   Consider both configuration and handling of data flow.
