• Python Scripte:
  • downloaden:

wget https://raspberrytips.nl/files/tm1637.py
wget https://raspberrytips.nl/files/47digitclock.py

• 4747digitclock.py für obige Schaltung anpassen:

• GPIO 23 auf GPIO 20 (RPi-Pin 16 auf 38)
• GPIO 24 auf GPIO 21 (RPi-Pin 18 auf 40)

import sys
import time
import datetime
import RPi.GPIO as GPIO
import tm1637

#CLK -> GPIO20 (Pin 38)
#DI0 -> GPIO21 (Pin 40)

Display = tm1637.TM1637(20,21,tm1637.BRIGHT_TYPICAL)

Display.Clear()
Display.SetBrightnes(1)

while(True):
   now = datetime.datetime.now()
   hour = now.hour
   minute = now.minute
   second = now.second
   currenttime = [ int(hour / 10), hour % 10, int(minute / 10), minute % 10 ]

   Display.Show(currenttime)
   Display.ShowDoublepoint(second % 2)

   time.sleep(1)

• ausführbar machen:

chmod +x *.py

• automatsich beim Booten starten:

sudo crontab -e

• Zeile einfügen:

@reboot /root/47digitclock.py &
