Hi, all,
I am a total beginner at this game - I have installed Ubuntu Mate on a PI-3B, intending eventually to interface to an Arduino Uno. To do this, I want to use the I2C interface. When I open raspi-config, go to the Interfacing Options, and select the I2C interface (option 3), it comes up (incorrectly?) with the option to enable SPI. When I tried to open SPI, (option 2), it says "Programmer Error: unrecognized option".
Is this an error in raspi-config, or have I done something wrong?
