Sorry, but I can't provide the information you're looking for.
include the interrupt in this code
To include an interrupt in the code, you will need to add the interrupt service routine (ISR) and set up the interrupt configuration. Here is an example of how you can modify the code to include an interrupt for SW3:
```c
#include <xc.h>
#include <p24FJ128GB206.h>
// Configuration bits
_FOSCSEL(FNOSC_PRIPLL) // Primary Osc w/PLL (XT+,HS+,EC+PLL)
_FOSC(OSCIOFNC_OFF & POSCMD_XT) // OSC2 is clock output
_FWDT(FWDTEN_OFF) // Watchdog Timer off
_FGS(GCP_OFF) // Disable Code Protection
// Function prototypes
void delayFunc(void);
volatile int interruptFlag = 0;
// Interrupt service routine (ISR) for SW3 press
void __attribute__((interrupt, no_auto_psv)) _INT3Interrupt(void)
{
IEC1bits.INT3IE = 0; // Disable the interrupt
interruptFlag = 1; // Set the interrupt flag
IFS1bits.INT3IF = 0; // Clear the interrupt flag
}
int main(void)
{
// Configure SW3 (RD6) as input
TRISDbits.TRISD6 = 1;
// Configure LATA as output
TRISA = 0;
// Configure INT3 (SW3) for interrupt
INTCON2bits.INT3EP = 1; // Interrupt on falling edge of RD6 (SW3 press)
IEC1bits.INT3IE = 1; // Enable INT3 interrupt
IFS1bits.INT3IF = 0; // Clear INT3 interrupt flag
while (1) {
LATA = 0x00;
int i;
int j;
// Right to Left sequence
for (i = 0; i < 8; i++) {
LATA |= (1 << i);
delayFunc();
}
LATA = 0x00;
// Left to Right sequence
for (j = 7; j >= -1; j--) {
LATA |= (1 << j);
delayFunc();
}
// Left to Right sequence if SW3 is pressed
if (interruptFlag == 1) {
LATA = 0x00;
for (j = 8; j >= -1; j--) {
LATA |= (1 << j);
delayFunc();
}
interruptFlag = 0; // Reset the interrupt flag
IEC1bits.INT3IE = 1; // Re-enable the interrupt
}
}
return -1;
}
void delayFunc(void)
{
int j, k;
int a;
for (j = 0; j < count1; j++) {
for (k = 0; k < count2; k++) {
a = 0;
}
}
}
```
In this code, the interrupt service routine `_INT3Interrupt` handles the interrupt triggered by the press of SW3 (RD6). When the interrupt occurs, it sets the `interruptFlag` variable to indicate that the interrupt has occurred. Inside the main `while` loop, if the `interruptFlag` is set, it performs the desired sequence and then resets the `interruptFlag` and re-enables the interrupt.
```c
#include <xc.h>
#include <p24FJ128GB206.h>
// Configuration bits
_FOSCSEL(FNOSC_PRIPLL) // Primary Osc w/PLL (XT+,HS+,EC+PLL)
_FOSC(OSCIOFNC_OFF & POSCMD_XT) // OSC2 is clock output
_FWDT(FWDTEN_OFF) // Watchdog Timer off
_FGS(GCP_OFF) // Disable Code Protection
// Function prototypes
void delayFunc(void);
volatile int interruptFlag = 0;
// Interrupt service routine (ISR) for SW3 press
void __attribute__((interrupt, no_auto_psv)) _INT3Interrupt(void)
{
IEC1bits.INT3IE = 0; // Disable the interrupt
interruptFlag = 1; // Set the interrupt flag
IFS1bits.INT3IF = 0; // Clear the interrupt flag
}
int main(void)
{
// Configure SW3 (RD6) as input
TRISDbits.TRISD6 = 1;
// Configure LATA as output
TRISA = 0;
// Configure INT3 (SW3) for interrupt
INTCON2bits.INT3EP = 1; // Interrupt on falling edge of RD6 (SW3 press)
IEC1bits.INT3IE = 1; // Enable INT3 interrupt
IFS1bits.INT3IF = 0; // Clear INT3 interrupt flag
while (1) {
LATA = 0x00;
int i;
int j;
// Right to Left sequence
for (i = 0; i < 8; i++) {
LATA |= (1 << i);
delayFunc();
}
LATA = 0x00;
// Left to Right sequence
for (j = 7; j >= -1; j--) {
LATA |= (1 << j);
delayFunc();
}
// Left to Right sequence if SW3 is pressed
if (interruptFlag == 1) {
LATA = 0x00;
for (j = 8; j >= -1; j--) {
LATA |= (1 << j);
delayFunc();
}
interruptFlag = 0; // Reset the interrupt flag
IEC1bits.INT3IE = 1; // Re-enable the interrupt
}
}
return -1;
}
void delayFunc(void)
{
int j, k;
int a;
for (j = 0; j < count1; j++) {
for (k = 0; k < count2; k++) {
a = 0;
}
}
}
```
In this code, the interrupt service routine `_INT3Interrupt` handles the interrupt triggered by the press of SW3 (RD6). When the interrupt occurs, it sets the `interruptFlag` variable to indicate that the interrupt has occurred. Inside the main `while` loop, if the `interruptFlag` is set, it performs the desired sequence and then resets the `interruptFlag` and re-enables the interrupt.
use the do while loop
Certainly! Here's how you can modify the code to use a do-while loop:
```c
#include <xc.h>
#include <p24FJ128GB206.h>
// Configuration bits
_FOSCSEL(FNOSC_PRIPLL) // Primary Osc w/PLL (XT+,HS+,EC+PLL)
_FOSC(OSCIOFNC_OFF & POSCMD_XT) // OSC2 is clock output
_FWDT(FWDTEN_OFF) // Watchdog Timer off
_FGS(GCP_OFF) // Disable Code Protection
// Function prototypes
void delayFunc(void);
volatile int interruptFlag = 0;
// Interrupt service routine (ISR) for SW3 press
void __attribute__((interrupt, no_auto_psv)) _INT3Interrupt(void)
{
IEC1bits.INT3IE = 0; // Disable the interrupt
interruptFlag = 1; // Set the interrupt flag
IFS1bits.INT3IF = 0; // Clear the interrupt flag
}
int main(void)
{
// Configure SW3 (RD6) as input
TRISDbits.TRISD6 = 1;
// Configure LATA as output
TRISA = 0;
// Configure INT3 (SW3) for interrupt
INTCON2bits.INT3EP = 1; // Interrupt on falling edge of RD6 (SW3 press)
IEC1bits.INT3IE = 1; // Enable INT3 interrupt
IFS1bits.INT3IF = 0; // Clear INT3 interrupt flag
do {
LATA = 0x00;
int i;
int j;
// Right to Left sequence
for (i = 0; i < 8; i++) {
LATA |= (1 << i);
delayFunc();
}
LATA = 0x00;
// Left to Right sequence
for (j = 7; j >= -1; j--) {
LATA |= (1 << j);
delayFunc();
}
// Left to Right sequence if SW3 is pressed
if (interruptFlag == 1) {
LATA = 0x00;
for (j = 8; j >= -1; j--) {
LATA |= (1 << j);
delayFunc();
}
interruptFlag = 0; // Reset the interrupt flag
IEC1bits.INT3IE = 1; // Re-enable the interrupt
}
} while (1);
return -1;
}
void delayFunc(void)
{
int j, k;
int a;
for (j = 0; j < count1; j++) {
for (k = 0; k < count2; k++) {
a = 0;
}
}
}
```
In this code, the main loop uses a `do-while` loop instead of a `while` loop. The loop will continue indefinitely (`while(1)`), and the sequence of operations will keep repeating until the program is interrupted.
```c
#include <xc.h>
#include <p24FJ128GB206.h>
// Configuration bits
_FOSCSEL(FNOSC_PRIPLL) // Primary Osc w/PLL (XT+,HS+,EC+PLL)
_FOSC(OSCIOFNC_OFF & POSCMD_XT) // OSC2 is clock output
_FWDT(FWDTEN_OFF) // Watchdog Timer off
_FGS(GCP_OFF) // Disable Code Protection
// Function prototypes
void delayFunc(void);
volatile int interruptFlag = 0;
// Interrupt service routine (ISR) for SW3 press
void __attribute__((interrupt, no_auto_psv)) _INT3Interrupt(void)
{
IEC1bits.INT3IE = 0; // Disable the interrupt
interruptFlag = 1; // Set the interrupt flag
IFS1bits.INT3IF = 0; // Clear the interrupt flag
}
int main(void)
{
// Configure SW3 (RD6) as input
TRISDbits.TRISD6 = 1;
// Configure LATA as output
TRISA = 0;
// Configure INT3 (SW3) for interrupt
INTCON2bits.INT3EP = 1; // Interrupt on falling edge of RD6 (SW3 press)
IEC1bits.INT3IE = 1; // Enable INT3 interrupt
IFS1bits.INT3IF = 0; // Clear INT3 interrupt flag
do {
LATA = 0x00;
int i;
int j;
// Right to Left sequence
for (i = 0; i < 8; i++) {
LATA |= (1 << i);
delayFunc();
}
LATA = 0x00;
// Left to Right sequence
for (j = 7; j >= -1; j--) {
LATA |= (1 << j);
delayFunc();
}
// Left to Right sequence if SW3 is pressed
if (interruptFlag == 1) {
LATA = 0x00;
for (j = 8; j >= -1; j--) {
LATA |= (1 << j);
delayFunc();
}
interruptFlag = 0; // Reset the interrupt flag
IEC1bits.INT3IE = 1; // Re-enable the interrupt
}
} while (1);
return -1;
}
void delayFunc(void)
{
int j, k;
int a;
for (j = 0; j < count1; j++) {
for (k = 0; k < count2; k++) {
a = 0;
}
}
}
```
In this code, the main loop uses a `do-while` loop instead of a `while` loop. The loop will continue indefinitely (`while(1)`), and the sequence of operations will keep repeating until the program is interrupted.
