- SPI exposed is also used for the ADC. Try not to use your own CS.
- ADC kernel module will return 12bit number but the ADC itself only has an
accuracy of 10bits. This ADC is only included on the arduino board.
+- AIO pins are treated as 0-5 in mraa_aio_init() but as 14-19 for everything
+ else. Therefore use mraa_gpio_init(14) to use A0 as a Gpio

--------------------
- gpio register access via /dev/uio is limited to pin2 and 3
- gpio interupts will only work on GPIO_EDGE_BOTH
- adc kernel module will return 12bit number. MRAA defaults shift this to 10bits
