Enable the SPI module

LN Digitals boards communicate with the Banana Pi through the SPI interface. The SPI interface driver is included in the latest Banana Pi distributions but is not enabled by default. You can load the SPI driver manually by running::
$ sudo modprobe spi-sun7i

And you can permanently enable it by commenting out the  blacklist spi-sun7i  line in  /etc/modprobe.d/bpi-blacklist.conf .
$ sudo nano /etc/modprobe.d/bpi-blacklist.conf

Then enable spi modules by adding  spi-sun7i  and  spidev  to  /etc/modules  $ sudo nano /etc/modules

The /dev/spidev* devices should now appear but they require special privileges for the user bananapi to access them. You can set these up by adding the following  udev rule <https://wiki.debian.org/udev> _ to  /etc/udev/rules.d/50-spi.rules  
KERNEL=="spidev*", GROUP="spi", MODE="0660"

with the following command::
$ sudo nano /etc/udev/rules.d/50-spi.rules

Then create the spi group and add the user bananapi::
$ sudo groupadd spi
$ sudo gpasswd -a bananapi spi

.. note:: To enable other users to access SPI devices, you can add them to the  spi  group with  gpasswd -a otheruser spi .
Enable GPIO access

Interrupts work by monitoring the GPIO pins. You'll need to give the user bananapi access to these by adding the following udev rule (all on one line) to  /etc/udev/rules.d/51-gpio.rules ::
SUBSYSTEM=="gpio*", PROGRAM="
/bin/sh -c 'chown -R root:gpio /sys/class/gpio &&
chmod -R 770 /sys/class/gpio;
chown -R root:gpio /sys/devices/platform/gpio-sunxi/gpio &&
chmod -R 770 /sys/devices/platform/gpio-sunxi/gpio'"

with the following command::
$ sudo nano /etc/udev/rules.d/51-gpio.rules

Then create the gpio group and add the user bananapi::
$ sudo groupadd gpio
$ sudo gpasswd -a bananapi gpio

You will have to reboot after setting up SPI and GPIO permissions.
