TonUINO All-In-One – Einen neuen Sketch erstellen

Nachdem ihr die Arduino-IDE eingerichtet habt könnt ihr einen neuen Sketch erstellen. Wir haben einige Pins definiert die die Komponenten auf der Platine fest miteinander verbindet.

Damit sich die Platine nicht sofort wieder ausschaltet wird der entsprechende Code in der setup()-Methode benötigt. Ausschalten könnt ihr die Platine indem ihr die powerOff()-Methode aufruft.

/*
   empty sketch to start a project
   D5, A6 and A7 are wired to the extension port.
   D6 is wired to the button breakout board (labled WS(D6)).
   D9 (RST), D10 (SDA), D11 (MOSI), D12 (MISO) and D13 (SCK) are wired to the nfc breakout board.
   the rest of the pins are hard wired as per below.
