RTI Interrupts and LED flashing. Write a C (or assembly) program to flash the LEDs on your demo board with the following patterns:
1. Turn on all LEDs for about 0.4 s and turn them off also for about 0.4 s.
2. Repeat step 1 three more times.
3. Turn on one LED at a time from left to right with each LED turned on for about 0.4 s.
4. Repeat step 3 three more times.
5. Turn on one LED at a time from right to left with each LED turned on for about 0.4 s.
6. Repeat step 5 three more times.
7. Turn LEDs driven by pins RB7 and RB0 on and off four times. The on-time and off-time are each about 0.4 s.
8. Turn LEDs driven by pins RB6 and RB1 on and off four times. The on-time and off-time are each about 0.4 s.
9. Turn LEDs driven by pins RB5 and RB2 on and off four times. The on-time and off-time are each about 0.4 s.
10. Turn LEDs driven by pins RB4 and RB3 on and off four times. The on-time and off-time are each about 0.4 s.
11. Turn LEDs driven by pins RB3 and RB4 on and off four times. The on-time and off-time are each about 0.4 s.
12. Turn LEDs driven by pins RB2 and RB5 on and off four times. The on-time and off-time are each about 0.4 s.
13. Turn LEDs driven by pins RB1 and RB6 on and off four times. The on-time and off-time are each about 0.4 s.
14. Turn LEDs driven by pins RB0 and RB7 on and off four times. The on-time and off-time are each about 0.4 s.
15. Go to step 1 and repeat.
You are required to use the RTI to generate the required delay and trigger the change of LED patterns.

Determining the wavelength of photon
: Calculate the amount of energy produced (in J) when one positron and one electron annihilate one another. Each particle has a mass of 9.1*10^-31kg. If that energy is carried away by two gamma rays photons, what is the wavelength of each photon?
