Question

Implement the design on Explorer 16 as Project 1. LED D10 will be used as the RUN LED indicator.
Knight rider code:
unsigned int count1 = 200;
unsigned int count2 = 200;

void main(void) {
while (1)
{

bool sw = PORTDbits.RD6;

if( toggleDirection ) {
LATA <<= 1;
}
else {
LATA >>= 1;
}

if( LATA == 0x80 ) toggleDirection = false;
if( LATA == 0x01 ) toggleDirection = true;

if( !sw ) {
if( !pressed ) {
if( toggleDirection ){
toggleDirection = false;
LATA = 0x80;
}
else {
toggleDirection = true;
LATA = 0x01;
}
pressed = true;
}
}
else {
pressed = false;
}

delayFunc();

}
return -1;
}
}

void delayFunc(void)
{
int j,k;
int a;

for(j = 0; j < count1; j++)
{
for(k=0; k < count2; k++)
{
a = 0;
}
}

}

Using the knight rider code above, do the following:
Write an simple application (in C) which does the following:
1. Make the RUN LED(D10) toggle at every 1.45 Seconds (exact) interval using one of the Timer (Timer 1) module of the Microcontroller.
2. The Knight Rider pattern now consists of 7 LEDs (D9-D3). If the switch (S3) is open, the pattern is from Left to Right direction. If the switch (S3) is closed, the pattern is from Right to Left direction.
3. Repeat the whole process in an infinite way.
4. To toggle the RUN LED, precisely at 1.45 Seconds interval, you need to use the interrupt mechanism for the Timer1.
