|
# 20.08.2015 ML create file
|
||||||
|
# 07.12.2018 ML port from MKL05Z32VLC4 to STM32L476RG
|
||||||
|
# 27.02.2019 ML change from absolute addresses to BASE + OFFSET notation and
|
||||||
|
# add more timer modules
|
||||||
|
# 09.03.2022 ML port from STM32F042K6T6 to STM32G431KBT6U

# Description:
|
||||||
|
# Connects assembly addresses for STM32G431 MCU to symbolic register names
|
||||||
|
# used in the datasheets.

|
# Notes:
|
||||||
|
# - default MCU speed at startup is 16 MHz.

= 4.1 Aufgabe 1 - C: GPIO
|
||||||
|
== Vorbereitungsfragen:
|
||||||
|
=== a. Wozu werden Pull-Up Widerstände bei der Abfrage von Tastern benötigt?
|
||||||
|
=== b. Wie werden Taster entprellt?
|
||||||
|
=== c. Wie wird ein einzelnes Bit in einem 32-bit Wort getoggelt, ohne die anderen Bits zu verändern?
|
||||||
|
`int x ^= (1 << 0);`
|
||||||
|
=== d. Was ist speziell bei der Programmierung von Mikrocontrollern unter dem Begriff Initialisierung zu verstehen?
|
||||||
|
=== e. An Welchen Pors des Mikrocontrollers sind die LEDS und Taster der STefi Light Patine angeschlossen?
|
||||||
|
=== f. Studieren Sie die wichtigsten Quelltextdateien des C-Projektes task1.c und Stefi-Light.h. Welche Register und welche Bits werden hier beschrieben? Suchen Sie in der ST-Dokumentation (Reference Manual) die beiden relevanten Kapitel heraus und vollziehen Sie die Bedeutung der getätigten Einstellungen nach.
|
||||||
|
=== g. Wie muss ein Pin konfiguriert werden damit er als Eingang verwendet werden kann?
|
||||||
|
=== h. Erstellen Sie ein detailliertes Flussdiagramm für Ihre Lauflicht-Applikation

= 3.2 Aufgabe 2 - ASM: Interrupts, Entprellen
|
||||||
|
== Aufgabenstellung:
|
||||||
|
Das Programm soll per Tastendruck den Zustand der LEDs wechseln. Taster *S1* soll *LED0* und *LED3* ein-bzw. auschalten, Taster *S1 LED1* und *LED2*
|
||||||
|
== Vorbereitungsfragen:
|
||||||
|
=== a. Welche vier Einträge stehen am Beginn der ARM Exception Vector Table?
|
||||||
|
#table(
|
||||||
|
columns: (1fr, auto, auto),
|
||||||
|
inset: 10pt,
|
||||||
|

|
||||||
|
table.header(
|
||||||
|
[*Postion*], [*Vektor*], [*Beschreibung*]
|
||||||
|
),
|
||||||
|
[0], [WWDG],
|
||||||
|
=== b. Wie viele Interrupt-Prioritätsstufen unterstützt ein ARM-Controller maximal?
