This is for the PIC32 Digilent Board

1.) Show the proper values for the TRISA, ANSELA, and LATA special function registers to drive the on board LEDs (LDO0 thru LD7) such that the odd LEDs (LD1, LD3, LD5, and LD7) are ON and the even LEDs are OFF. 2.) What GPIO pins are BTNL, BTNR, and BTNC connected to? How would you set up the TRIS register for these buttons? 3.) List and describe the states/modes in your Mid-stage Project 1 demo. 4.) When pressing a button, you expect only a single contact recognized by the MCU. However, due to the so-called "bouncing" effect, multiple contacts may be recognized. How do you solve this problem in software? before it is released. How can you "lock" the state transition so that no more than one transition happens before you release the button
