Hallo zusammen,
bin ziemlicher Beginner mit dem ArduinoBoard und bin inzwischen bei den RF24-Beispielen angelangt.
Hier habe ich das LED_Remote-Beispiel nachgestellt was auch funktionierte.
Als nächstes habe ich ein LCD-Display am LED-Arduino (UNO) angeschlossen welches mir den Status zweier LEDs ausgibt. Auch kein Problem.
Nun wollte ich am Remote-Arduino (Mega) ein zusätzliches Keypad anschliessen und bekomme hier einfach keine Ausgabe vom Keypad.
Die Verkabelung passt, da ich das Keypadbeispiel mit den Pins nachstellte und hier funktionierte es.
Anbei der Code:

/**
* Example LED Remote
*
* This is an example of how to use the RF24 class to control a remote
* bank of LED's using buttons on a remote control.
*
* On the 'remote', connect any number of buttons or switches from
* an arduino pin to ground. Update 'button_pins' to reflect the
* pins used.
*
* On the 'led' board, connect the same number of LED's from an
* arduino pin to a resistor to ground. Update 'led_pins' to reflect
* the pins used. Also connect a separate pin to ground and change
* the 'role_pin'. This tells the sketch it's running on the LED board.
*
* Every time the buttons change on the remote, the entire state of
* buttons is send to the led board, which displays the state.

Wäre dankbar wenn mir hier jemand helfen könnte.
