11.3. ARM CMSIS for Peripheral Drivers

Try these first

1. 1.

   What is the purpose of GPIO in embedded systems?

   Hint

   Think about controlling lights or reading sensors.

2. 2.

   How do we start a timer using CMSIS?

   Hint

   Look for a command that includes 'CEN'.

3. 3.

   What does CMSIS stand for?

   • Central Microcontroller Software Interface Standard
   • Cortex Microcontroller Software Interface Standard
   • Cortex Memory Software Interface Standard

   Hint

   Focus on the Cortex architecture.

4. 4.

   True or False: GPIO pins can only work as outputs and cannot read input.

   • True
   • False

   Hint

   Remember, GPIO stands for General Purpose Input/Output.

5. 5.

   Create a program that uses both GPIO and Timers to blink an LED on and off every second.

   Hint

   Consider using the Timer’s interrupt to manage the LED state change.

6. 6.

   Design a UART communication protocol to transmit temperature data from a sensor using CMSIS.

   Hint

   Think about how to structure your output data and manage transmissions.
