Description ​

  1. Typical architecture and basic operation of a microprocessor system
    • study of operating principles and architectures (VonNeuman/Harvard)
    • programming a microprocessor: application to the case of the ARM Cortex M4
    • implementation of a development chain for testing and debugging
  2. Access to peripherals: application to the STM32F411 microcontroller
  3. Study of exception mechanisms: hardware exceptions or interruptions
  4. General information on serial link communications and study of UART and I2C links

Learning Outcomes AAv (AAv) ​

  • AAv1 [heures: 30, D1, D2, D3, D4] : The student of the microprocessor course, at the end of the semester, will know how to compose and test a program written in ARM assembly language using development tools, to the compilation and visualization of registers and memory contents, respecting the AAPCS standard, in order to execute a program for calculating or processing character strings on an STM32 microcontroller.

  • AAv2 [heures: 33, D1, D2, D3, D4] : The student of the microprocessors course, at the end of the semester, will be able to interact an STM32 microcontroller with LEDs, push buttons and a request signal. 'interruption external to the microcontroller by implementing the GPIO peripheral of the microcontroller, first by direct use of its registers then by use of a GPIO management API to be developed, with the exception of the initialization function provided, in order to drive LEDs , to recover the state of push buttons and to interrupt the current program to execute the interrupt service routine associated with the external request.

  • AAv3 [heures: 24, D1, D2, D3, D4] : The student of the microprocessors course, at the end of the semester, will be able to use a timer to control a timer or the period of periodic interruptions or generate a pulse width modulated signal, modify its duty cycle and apply it to a physical pin of the STM32 microcontroller, using, in a guided framework, the timer register interface, then completing an API encapsulation of the timer functionalities to obtain a duration or a PWM signal conforming to that expected.
