+## Board IO and ioctl
+
+OpenEMC allows direct communication between Linux userspace and board-specific code.
+For this purpose the device `/dev/openemc` is provided, which supports reading, writing, polling
+and ioctls.
+Corresponding to these operations the board-specific functions `Board::io_read`, `Board::io_write` and
+`Board::ioctl` are called.
+An example is provided in the board file `stm_nucleo_f103rb.rs` together with the host-side code
+in `board-io-test`.
