}
By switch 7, LD4 turns on
By switch 5, LD6 turns on
By switch 2,3 OR GATE LD2
By switch 0,2 AND GATE LD1
Overall output :
Conclusion:
Done all task in the with the help of manuals pins assignment on PIC32MX370F512L
Microcontroller and experimented tasks like generating header file and running with switching buttons
and implementing OR and AND gate on PIC32MX370F512L.
