Interrupt Service Routine on esp32

[MohamedTrabelsi]

Hello guys I'm working on a project that activate wifi interface when a button is pressed so I created a project that print a message when the event is triggered the code works fine but when I integrated the same code in the main project the interruption doesn't work

Code: [Select all] [Expand/Collapse]

1. #include <stdio.h>
2. #include "freertos/FreeRTOS.h"
3. #include "freertos/task.h"
4. #include "freertos/semphr.h"
5. #include "driver/gpio.h"
6. #define BUTTON_PIN GPIO_NUM_2
7.  
8. // Semaphore to synchronize tasks
9. SemaphoreHandle_t xSemaphore = NULL;
10.  
11. // Interrupt service routine for the button press
12. static void IRAM_ATTR button_isr_handler(void* arg) {
13.     // Notify the waiting task that the button was pressed
14.     xSemaphoreGiveFromISR(xSemaphore, NULL);
15. }
16.  
17. // Task that will be notified when the button is pressed
18. void button_task(void *arg) {
19.     while (1) {
20.         // Wait for the semaphore to be given by the ISR
21.         if (xSemaphoreTake(xSemaphore, portMAX_DELAY)) {
22.             esp_wifi_start();
23.             printf("Button Pressed!\n");
24.         }
25.     }
26. }
27. void vTaskISR(void *pvParameters)
28. {  
29.     while(1)
30.     {
31.      xSemaphore = xSemaphoreCreateBinary();
32.  
33.     // Configure the GPIO pin for the button
34.     gpio_config_t io_conf = {
35.         .pin_bit_mask = (1ULL << BUTTON_PIN),
36.         .mode = GPIO_MODE_INPUT,
37.         .intr_type = GPIO_INTR_POSEDGE,  
38.         .pull_up_en = GPIO_PULLUP_ENABLE,
39.     };
40.     gpio_config(&io_conf);
41.  
42.     // Install ISR service with default configuration
43.     gpio_install_isr_service(0);
44.  
45.     // Hook ISR handler to the button pin
46.     gpio_isr_handler_add(BUTTON_PIN, button_isr_handler, (void*) BUTTON_PIN);
47.     vTaskDelete(NULL);
48.     }
49. }
50.  
51. void app_main() {
52.     xTaskCreate(&vTaskISR, "ISR", 4096, NULL, 5, NULL);
53. }

You should actually xTaskCreate a task if you want it to do something
