SPI Help

15 August 2010 - 09:44 PM

What about the following code is causing an exception to be thrown when I create a new SPI object? The exception says

#### Exception System.Exception - CLR_E_PIN_UNAVAILABLE (2) ####
#### Message:
#### Microsoft.SPOT.Hardware.Port::.ctor [IP: 0000] ####

        public static SPI.Configuration spi_config = new SPI.Configuration(Pins.GPIO_PIN_D13,
                                      false,
                                      1,
