Der 433 MHz Funksender f\u00fcr den I2C-Bus\u00a0ist jetzt fertig<\/p>\n

\"I2C-Funksender<\/a>

I2C-Funksender f\u00fcr Hutschiene<\/p><\/div>\n

 <\/p>\n

Mit dem neuen Funkmodul k\u00f6nnen Sie ohne viel Aufwand 433,92 MHz Funksteckdosen z.B. von Pollin (Best.Nr. 550\u00a0666 oder\u00a0551\u00a0373) mit einer\u00a0schalten.<\/p>\n

Antenne<\/h2>\n

Das Modul kann wahlweise\u00a0mit einer einfachen Drahtantenne, mit einer Funkantenne oder falls gew\u00fcnscht mit einer SMA-Buchse f\u00fcr eine externe Antenne best\u00fcckt werden.<\/p>\n

Protokolle<\/h2>\n

Am DIP-Schalter das gew\u00fcnschte Protokoll z.B. „1\u00a0f\u00fcr Pollin Funksteckdosenset“ ausgew\u00e4hlt werden.<\/p>\n

Weitere Protokolle z.B. f\u00fcr Goobay oder Brennenstuhl Funksteckdosen f\u00fcgen wir im Lauf der Zeit hinzu. \u00dcber ein Firmware-Update k\u00f6nnen neue Funktionen jederzeit auf das Modul geladen werden.<\/p>\n

Ansteuerung<\/h2>\n

Die Ansteuerung \u00fcber den I2C-Bus ist sehr einfach gehalten.<\/p>\n

Systemcode \u00fcbertragen<\/h5>\n

Zuerst muss einmal der an der Steckdose eingestellte Systemcode zum Modul \u00fcbertragen werden.<\/p>\n

Bei den Pollin-Dosen wird der Systemcode an den DIP-Schaltern 1-5 eingestellt.<\/p>\n

\"DIP-Schalter<\/a>

DIP-Schalter 1-5 bei Pollin Funksteckdose<\/p><\/div>\n

Der Systemcode wird\u00a0im „I2C 433 MHz-Sender“ in das Register\u00a00\u00a0abgelegt.<\/p>\n

Das Register 0 hat 5 Byte. Der Schreibbefehl muss immer mit der Nummer des zu schreibenden Registers beginnen.<\/p>\n

Ist der DIP-Schalter\u00a0ON muss in das entsprechende Byte eine „0“ (0x00 hex) eingetragen werden.
\nIst der DIP-Schalter OFF muss eine „15“ (0x0F hex) eingetragen werden.<\/p>\n

Sind wie in dem Bild\u00a0die DIP-Schalter 1-5 alle auf ON sieht der Schreibbefehl in das Register wie folgt aus:<\/p>\n

\u00a0\u00a0\u00a0\u00a0Wire.beginTransmission<\/span>(I2C_ADDR);    \/\/ Start \u00dcbertragung zur I2C-433MHz-Karte<\/span>\r\n\u00a0\u00a0\u00a0\u00a0Wire.write<\/span>(0);\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0    \/\/ Register 0\r\n<\/span>\u00a0\u00a0\u00a0\u00a0Wire.write<\/span>(0);\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0   \u00a0\/\/ DIP1=ON => 0 (oder 15 wenn DIP1=OFF)\r\n<\/span>\u00a0\u00a0\u00a0\u00a0Wire.write<\/span>(0);\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0  \u00a0\u00a0 \/\/ DIP2=ON => 0 (oder 15 wenn DIP2=OFF)\r\n<\/span>\u00a0\u00a0\u00a0\u00a0Wire.write<\/span>(0);\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0    \/\/ DIP3=ON => 0 (oder 15 wenn DIP3=OFF)\r\n<\/span>\u00a0\u00a0\u00a0\u00a0Wire.write<\/span>(0);\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0   \/\/ DIP4=ON => 0 (oder 15 wenn DIP4=OFF)\r\n<\/span>\u00a0\u00a0\u00a0\u00a0Wire.write<\/span>(0);\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0  \u00a0  \/\/ DIP5=ON => 0 (oder 15 wenn DIP5=OFF)\r\n<\/span>\u00a0\u00a0\u00a0\u00a0Wire.endTransmission<\/span>();\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\/\/ Ende<\/span><\/pre>\n
\u00a0Funksteckdosen ansteuern<\/h5>\n
Als n\u00e4chstes wird die zu schaltende Steckdose angesteuert indem man ins Register 1 die Steckdosen-Nummer schreibt die geschaltet werden soll.
\nZum AUS-schalten die einfache Nummer,
\nzum EIN-schalten die Steckdosen-Nummer + 128<\/p>\n
Ist wie im Bild der\u00a0DIP-Schalter A auf ON muss zum Ein<\/strong>schalten folgender Schreibbefehl gesendet werden::<\/p>\n
    Wire.beginTransmission<\/span>(I2C_ADDR);    \/\/ Start \u00dcbertragung zur I2C-433MHz-Karte<\/span>\r\n    Wire.write<\/span>(1);                       \/\/ Register 1\r\n<\/span>    Wire.write<\/span>(129);                     \/\/ DIPA=ON => 129 = zum Einschalten senden<\/span>\r\n    Wire.endTransmission<\/span>();              \/\/ Ende<\/span><\/pre>\n
Zum Ausschalten muss\u00a0einfach nur die Steckdosen-Nummer geschrieben werden:<\/p>\n
