Voraussetzungen :
\n1x Raspberry Pi Model B
\n1x Spannungswandler f\u00fcr I2C Bus (selbstbau mit 74HCT00)
\n1x Netzteil
\nLED Leiste WS2801 mit entsprechender L\u00e4nge<\/p>\n

Pegelwandler :
\nDa der I2C Bus des Raspberry einen 3,3 Volt Pegel ausgibt, jedoch der Eingang des WS2801 einen 5V Pegel ben\u00f6tigt kommt der 74HCT00 zum Einsatz. Wichtig ist, das es sich um die HCT Variante handelt, da nur diese am Eingang 3,3V Pegel “versteht” aber 5V Pegel ausgibt.
\nDa der 74HCT00 ein Invertiert, werden die beiden Eing\u00e4nge gebr\u00fcckt, und nochmals negiert.
\nEine genaue Dokumentation ist hier zu finden :\u00a0https:\/\/github.com\/tvdzwan\/hyperion\/wiki\/hardware<\/a><\/p>\n

RASPI-CONFIG :
\nUm Hyperion verwenden zu k\u00f6nnen muss im Raspi SPI aktiviert sein.
\nSPI kann \u00fcber “raspi-config” aktiviert werden. Nach der Aktivierung erfolgt die abfrage, ob die Kernel Module beim Start in den Kernel eingebunden werden sollen. Dies sollte auch mit Ja best\u00e4tigt werden.<\/p>\n

PAKETE :
\nsudo apt-get update
\nsudo apt-get upgrade<\/p>\n

sudo apt-get install libqtcore4 libqtgui4 libqt4-network libusb-1.0-0 libprotobuf7 ca-certificates<\/code><\/p>\n
