I'm working on a Duo project that needs SPI and this is how I configured and tested it without the mini shield.
Requirements:
NanoPi Duo with test Armbian image
1 female to female jumper wire
Enable SPI on boot:
sudo nano /boot/armbianEnv.txt
Add spi-spidev to overlays=
Add line param_spidev_spi_bus=1
sudo reboot
If everything worked you should have /dev/spidev1.0. Check with ls /dev/spi*. Now we can test with a C program:
cd
wget
