+====== The LCD Display ======
+Another way to visualize the CAN messages is to connect the LCD display as
+shown in the photo below. The display will show all messages transmitted on
+the CAN bus with its message ID. Therefore it is necessary to ﬂash the other
+HEX-ﬁle (candisplay.hex) to the ATMega32 to which the display should be con-
+nected.  After ﬂashing the program onto it, this controller will only work with
+the attached display, and the board will not be able to send messages. Before the
+controller can display the messages the baud rate has to be selected.  To select
+it the keys on the board ("KEY1" and "KEY2", not the RESET-key) have to be
+used.  "KEY1" changes the baud rate shown in the display from 10 kbps up to
+Mbps.  When the desired baud rate is shown in the display it has to be con-
+ﬁrmed by pressing "KEY2". Now the controller can show the CAN messages on
+the display.
