#
# Author: Manuel Lederhofer
# Datum: 31.10.2014
#
# Version: 6.0
# History:
# 31.10.2014 ML create file
# 27.09.2018 ML edit comments, extend vector table
# 18.12.2018 ML port from MKL05Z32VLC4 to STM32L476RG
# 27.02.2019 ML move section of exception handlers to bottom of file
# 25.09.2019 ML minor changes for a better code and comment understanding
# 04.09.2020 HL port from STM32L476RG to STM32F411xE
# 21.09.2020 ML tidy up, comments and formatting
# 29.09.2021 ML port from STM32F411xE to STM32F042K6T6
# 09.03.2022 ML port from STM32F042K6T6 to STM32G431KBT6U
# 10.02.2025 TK remove ASM:Polling,move ASM:Interrupts to task2
# 24.06.2025 TK remove /* ... place your code here ... */
#
# Status: working
#
# Description:
# See the description and requirements of the requested application
# in the lab exercise guide.
#
# Notes:
# - MCU speed at startup is 16 MHz
#
# ToDo:
# - Change the example code to match the description and requirements
# of the requested application in the lab exercise guide.

= 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,
align: horizon,
table.header(
[*Postion*], [*Vektor*], [*Beschreibung*]
),
[0], [WWDG],
=== b. Wie viele Interrupt-Prioritätsstufen unterstützt ein ARM-Controller maximal?
=== c. An welchen Positionen in der Exception Vector Table stehen die Adressen der ISRs für die Tasten? (ST Dokumentation)
=== d. Schauen Sie sich das Prellen eines Tasters an und überlegen Sie sich eine Lösung.
=== e. Erstellen Sie ein komplettes Flussdiagramm für Ihren Lösungsansatz.
