Altera DE2 LCD

This is a very simple design that initializes the Altera DE2 LCD and displays 32-bit hexadecimal numbers. To get initialization, commands and timing, use the datasheet for the LCD part number CFAH1602B-TMS-JP supplied with the DE2 CD-ROM in the datasheet folder.
There are three modules in this design.  lcd_display simplifies the interface to the LCD by taking care of generating the correct signals to the LCD with proper timing. It waits for the self-initialization process of the LCD to finish and then accepts user input. The user indicates if the input data is a command or a write and the delay to wait after the input data is given to the LCD. This way the user does not need to take care of any timing and is advised of the completion of the command with a signal. For the Altera board this module is simpler than for the Xilinx board because the LCD interface is used in 8-bit mode rather than 4-bit mode

lcd_write_number is a module that initializes the LCD and then waits for a 32-bit number input from a user to display in hexadecimal representation.

Finally, the test module lcd_write_number_test uses the lcd_write_number module to display a running 32-bit counter on the display.
