Question 1:

Write an AVR program to display text on a 2-line WH2002 LCD display based on the HD44780 controller. Apply the following:

The LCD instruction/data bus is connected to PORTD, and control bus is connected to PORTB (RS is connected to PB0, R/W to PB1, E to PB2).
Use the #define command to name PORTD as Display_port.
Use the #define command to name PORTB as Control_port.
The displayed information is stored in the microcontroller Flash ROM (maximum size of 80 bytes) in the tables "str_0" (upper line) and "str_1" (lower line), as follow:
- str_0 = AMA INTERNATIONAL UNIVERSITY
- str_1= COLLEGE OF ENGINEERING
Use 0x18 command to scroll the text across the display (Shift the cursor left)

Write Java program Lab52.java which reads in a line of text from the user. The text should be passed into the method: public static String[] divideText(String input) The "divideText" method returns an array of 2 Strings, one with the even number characters in the original string and one with the odd number characters from the original string. The program should then print out the returned strings.

Write a complete Python program that asks the user for a line of text (not just a single word), and then tells the user whether the string is a palindrome (same forward and backward) if you ignore case and non-alphabetic characters. The following methods and functions may be useful: str.upper(), str.isalpha() -> bool, reversed(str) -> sequence, str.find(str) -> int, str.replace(str, str), str.center(int). Unless otherwise specified, they all return a string.
