Note:
- To input a number you have to enter it digit by digit then press #
Program starts to enter the index of the Fibonacci number you wish to end at it.
So if you enter 8, the program with output the first 8 Fibonacci numbers: 0, 1, 1, 2, 3, 5, 8, 13
When you hit "8" on the keypad now number have "8". To end editing in number hit "#" and the Fibonacci Series will appear on the display.
So if you enter 8, the program with output the first 8 Fibonacci numbers: 0, 1, 1, 2, 3, 5, 8, 13
When you hit "8" on the keypad now number have "8". To end editing in number hit "#" and the Fibonacci Series will appear on the display.
Output
The output can appear on 7 Segment Display based on PORTD(Data Port) & PORTA(Control Port).
The series will appeared with delay between them.
The series will appeared with delay between them.
