spi

[anemos]

How is spi working with nano pi neo air?
is there a C library to load to make it working?
what about the i2c buses is that supported yet?

i2c is working fine with Friendlyarm's Ubuntu. You just have to:

Code: Select all

apt-get install i2c-tools -y
apt-get install python-smbus -y
usermod -aG i2c fa # for convenience

I tested a couple of i2c sensors and an i2c display without any issues:

With Armbian, not all i2c devices are recognized properly (ie i2cdetect does not display all devices).

I didn't test spi so far and i still have some issues with 1-wire (DS18B20):
