Closed max90727 closed 9 years ago

max90727 commented 9 years ago

Hi. I write some code for reading the digital input, but I got the error as "could not create pin". Please help me. Board board = Platform.createBoard(); DigitalInput digitalInput=board.getPin(BBBNames.P8_12).as(DigitalInput.class); Signal signal=digitalInput.read(); System.out.println(signal.getNumericValue());

Hello, are you running your code as root? Are there any exceptions printed?

Hi max90727, I fixed the code that most likely caused your issue. Can you please try your code now and confirm it works for you?

Thanks!

Thanks for your help. My project goes fine now, and I found that I can read the signal from my temperature sensor by building the device tree. Anyway, still thanks for your help and I will try that when I have more time.
