There are ## three possible configuration options, and they all expect integer values: ## speed - the clock speed in Hz ## mode - the SPI mode (0, 1, 2, 3) ## bits - the length of each word, in bits (defaults to 8, which is standard) ## It is also possible to pass a device name, but the default, spidev0.0, is ## the only device currently supported by the pcDuino. spi.openSPI(speed=1000000, mode=0) ## Data is sent as a tuple, so you can construct a tuple as long as you want ## and the result will come back as a tuple of the same length. print spi.transfer((0x0B, 0x02, 0x00)) ## Finally, close the SPI connection. This is probably not necessary but it's ## good practice. spi.closeSPI()
