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.
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.
The interrupt for the given code is not explicitly shown in the code provided. However, if you want to add an interrupt to the code for the Explorer 16, you can do so by following these steps:
1. Identify the interrupt source that you want to use. For example, if you want to use the external interrupt INT0, you would need to connect the interrupt source to the INT0 pin on the Explorer 16 board.
2. Configure the interrupt settings. This involves setting up the appropriate registers to enable and configure the interrupt. For example, for INT0, you would need to set the INT0 pin as an input, enable the external interrupt, and choose the interrupt edge or level trigger.
3. Implement the interrupt service routine (ISR). The ISR is the code that will be executed when the interrupt occurs. In the ISR, you can perform any necessary actions or modifications to the program state. For example, if you want to stop the sequence when the interrupt occurs, you can add code to exit the while loop or set a flag to indicate the interrupt.
4. Attach the ISR to the interrupt vector. This involves assigning the ISR function to the appropriate interrupt vector. For example, for INT0, you would assign the ISR function to the INT0 vector.
Here is an example of how you could modify the code to add an interrupt using the INT0 pin:
```c
#include <p24FJ128GA010.h>
// Global variable to indicate interrupt occurrence
volatile int interruptFlag = 0;
void __attribute__((interrupt, no_auto_psv)) _INT0Interrupt(void)
{
// Clear the interrupt flag
IFS0bits.INT0IF = 0;
// Set the interrupt flag to indicate interrupt occurrence
interruptFlag = 1;
}
int main(void)
{
// Configure INT0 pin as an input
TRISBbits.TRISB7 = 1;
// Configure INT0 as external interrupt with falling edge trigger
INTCON2bits.INT0EP = 1; // Trigger on falling edge
IFS0bits.INT0IF = 0; // Clear the interrupt flag
IEC0bits.INT0IE = 1; // Enable INT0 interrupt
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 interrupt is triggered
if(interruptFlag) {
LATA = 0x00;
for(j=8; j>=-1; j--) {
LATA |= (1<<j);
delayFunc();
}
// Clear the interrupt flag
interruptFlag = 0;
}
}
return -1;
}
```
In this example, the INT0 interrupt is configured to trigger on the falling edge of the INT0 pin. When the interrupt occurs, the ISR `_INT0Interrupt` is executed, which sets the `interruptFlag` variable to indicate the interrupt occurrence. Inside the while loop, the interrupt flag is checked, and the modified sequence is executed if the flag is set. The interrupt flag is cleared after the modified sequence is executed.
To add an interrupt in the code for the Explorer 16, you would need to follow these steps:
1. Determine the interrupt source: You need to choose the specific interrupt source you want to use. For example, if you want to use an external interrupt, identify the appropriate interrupt pin and register.
2. Configure the interrupt: Configure the appropriate registers to enable the interrupt, set the priority, and configure any necessary options. This usually involves setting the interrupt enable bit in the relevant register.
3. Define the interrupt service routine (ISR): Write the code for the interrupt service routine. This is the code that will be executed when the interrupt occurs. It should handle the required tasks or actions.
4. Enable global interrupts: Enable the global interrupt feature. This allows other interrupts to occur while the current interrupt is being handled.
Here is an example of how you can modify the code to add an interrupt for the Explorer 16:
```c
#include <xc.h>
void __attribute__((interrupt, auto_psv)) _INT0Interrupt(void)
{
// ISR code for the interrupt
// Perform the required actions or tasks here
// ...
// Clear the interrupt flag if necessary
IFS0bits.INT0IF = 0;
}
int main()
{
// Configure the interrupt pin and register for the desired interrupt source
// ...
// Configure the interrupt settings and priority
// ...
// Enable the interrupt and global interrupts
// ...
// Initial code
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(PORTDbits.RD6 == 0) {
LATA = 0x00;
for(j = 8; j >= -1; j--) {
LATA |= (1 << j);
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;
}
}
}
```
Remember to replace the comments with the appropriate code for configuring and enabling the specific interrupt source on the Explorer 16 board.
