TempCTRL v1 firmware
Version vom 31. Januar 2016, 09:32 Uhr von Case (Diskussion | Beiträge)
Hier die aktuelle Firmware-Version für TempCTRL V.1, namens "heizkreisrelais7". (Stand 30.01.2016)
Sie benötigt noch eine externe Library namens "UIPEthernet" und erlaubt die Verwendung von ENC28J60 Ethernet-Modulen, welche äusserst preisgünstig zu haben sind, im Unterschied zum klassischen W5100-Ethernet-Shield für Arduino. Früher konnte der ENC28J60 nur mit einer externen Library namens "EtherCard" betrieben werden, aber die Funktionsaufrufe der Ethercard-Library sind nicht kompatibel zur Standard-Ethernet-Library der Arduino-IDE, weshalb sie eben separat benötigt wird. Es gibt aber mittlerweile auch die Möglichkeit, einen ENC28J60 mittels UIPEthernet mit standard-konformen Funktionsaufrufen zu betreiben, weshalb diese hier zum Einsatz kommt.
