1. Write a program (in a project called test) which will test every character position on the display. It should do this by moving to each position in turn and writing something to it. Remember that you will need to think of a name for the source file in the project as well.
    Exercise 5.3

  2. If you send the command value 0x0f to the LCD panel you can turn the cursor on. This will cause the character at the cursor position to flash. If you send the command 0x0c the cursor is turned off again. Add two functions, called lcd_cursor_on and lcd_cursor_off to the lcd library. Make sure that you update the include files with prototypes for the new functions.
