HW 02 - First program on embedded platform

• Get familiar with the HW - NUCLEO and especially with the NUCLEO-F401RE
• The description of the board available in one document.
• With help of STM32 CubeMX find the correct settings of the clock distribution for NUCLEO STM32F401 - Revision MB1136 C-03 - see chapter 6.7 OSC clock.
• Propose a concept of the communication protocol structure (list of commands and line endings) - e.g. Standard Commands for Programmable Instruments (SCPI) interface.
• Get familiar with the extension board 802 and its interconnection with NUCLEO

Show to the lab instructor you can:

• Compile the test project
• Transmit the data from NUCLEO to PC (known serial interface)
• Present a report containing:
  • proposal of the communication protocol - what will be the reply for identification request (e.g. *IDN? command)
  • list of I/O pins used to control the LED
  • list of I/O pins used to control and read the state of the button
• Determine why the serial line initialization requires multiplication by 3

These parameters of the program will be evaluated:

• 1 point - student is able to compile and upload the program to the Nucleo board.
• 1 point - student is capable to set a break point in the code, stop the execution of the code on a condition and resume the program operation
• 1 point - student will present a list of command which will be sent from computer to Nucleo with description what these commands will do
• 1 point - student will present a list of pins to control LED and Button
• 1 point - the program will be able co control the state of the LED based on button e.g. when the button is pressed the LED will switch on and opposite.

extra point

• 1 point - student will create a report comparing the StdLib and CubeMX HAL libraries, e.g. definition, what they are, what are the differences.
