I need help with writing some code for the BOLD part down below

#include

#include

#include

#include "launchpad.h"

#include "seg7.h"

#include "seg7digit.h"

// Stop watch increment function, written in assembly

extern void

stopWatchIncrement(seg7Display_t* seg7Display);

// The running state of the stopwatch system

enum {

Reset, Run, Pause

} sysState = Run;

// The initial state of the 7-segment display: "00:00" with colon on

seg7Display_t seg7Display = {

0, 0, 0, 0, 1

};

// Callback function for updating clock watch

void

stopWatchUpdate(uint32_t time) // The scheduled time

{

// Update clock and display, only if the stopwatch is running

if (sysState == Run) {

stopWatchIncrement(&seg7Display);

}

seg7DigitUpdate(&seg7Display);

// Call back after 10 milliseconds

schdCallback(stopWatchUpdate, time + 10);

}

// Callback function for checking push button. SW1 is the RESET button, and

// SW2 is the START/PAUSE/RESUME button.

void

checkPushButton(uint32_t time)

{

int code = pbRead();

uint32_t delay;

switch (code) {

case 1: // SW1 is the Reset button, only when the stopwatch is paused

//

// YOUR CODE

//

delay = 250; // software debouncing

break;

case 2: // SW2 is the Start/Pause/Resume button

//

// YOUR CODE

//

delay = 250; // software debouncing

break;

default:

delay = 10;

}

schdCallback(checkPushButton, time + delay);

}

int main(void)

{

lpInit();

seg7Init();

uprintf("%s ", "Lab 3: Stopwatch");

// Update the clock display

seg7DigitUpdate(&seg7Display);

// Schedule the first callback events for LED flashing and push button checking.

// Those trigger callback chains. The time unit is millisecond.

schdCallback(stopWatchUpdate, 1000);

schdCallback(checkPushButton, 1005);

// Run the event scheduler to process callback events

while (true) {

schdExecute();

}

}
