Software

1. Install Raspberry Pie OS (32-bit) on a micro SD card
2. Set up your RCT-module

• Activate I2C -> raspi-config
• i2cdetect -y 1 to check for the RTC, it should show 68
• sudo nano /etc/modules and add rtc-ds3231
• sudo nano /boot/firmware/config.txt and add dtoverlay=i2c-rtc,ds3231
• sudo apt-get -y remove fake-hwclock
• sudo nano /lib/udev/hwclock-set and comment from the first if to first fi
• reboot
• Check if the RTC is working with sudo hwclock -r
• And write the correct time with sudo hwclock -w

3. Copy clock.py in your /home/USER directory

4. Create a autostart directory (if not present) and do not use sudo

   mkdir /home/USER/.config/autostart

5. Create a .desktop file with nano

   nano /home/USER/.config/autostart/clock.desktop

   Content :

   [Desktop Entry]
   Type=Application
   Name=Clock
   Exec=/usr/bin/python3 /home/USER/Intensivuhr/clock.py
   

6. Reboot
