DE0-nano

Does DE0-nano have I2C bus? If so can someone explain to me how to use it on the nano.

An external I2C interface can be set up with two I/O pins of your choice at the expansions header. The board has an internal I2C interface wired to some periperals, but it's signals are not exposed to the outside. The I2C interface functionality (master or slave) has to be implemented in the FPGA design. Example code driving the internal I2C devices can be found in the demonstrations.
