Interrupting higher priority task from webserver command

[progit]

Hello All,

I am new to using the esp32 and am trying to figure out how to make a "Abort" button on my esp32 webpage abort a for loop in a higher priority task (task pulses in code below). The problem is that when the for loop in the Pulse Code below is running, the webserver is blocked and I cannot interrupt the for loop.
Any idea on how to implement an abort on the webpage.

Main code:

Code: Select all

  
  ...
  server = start_webserver();
  xTaskCreate(&pulses, "pulses", 2048, NULL, 2, NULL);
  ...

Webserver Code:

Code: Select all

...
httpd_uri_t root = {...     .handler = root_get_handler ...};

httpd_register_uri_handler(server, &root);

esp_err_t root_get_handler(httpd_req_t *req)
{ 
	if  (httpd_query_key_value(buf, "run", param, sizeof(param)) == ESP_OK) { 
			xQueueSend(pulsequeue, &steps, 1000 / portTICK_PERIOD_MS) ; 
	}
        if  (httpd_query_key_value(buf, "abort", param, sizeof(param)) == ESP_OK) { 
        	NEED HELP HERE; 
        }
}

Pulse Code:

Code: Select all

void pulses(void *pvParameters)
{
  ...
   if (xQueueReceive(pulsequeue, &r, 1000 / portTICK_PERIOD_MS))
            {  
                for (uint a = 0; a < abs(r) * 1000; a++){
                    gpio_set_level(pin1, 0)
                    vTaskDelay(delay / portTICK_PERIOD_MS);
                    gpio_set_level(pin1, 1);
                    vTaskDelay(delay / portTICK_PERIOD_MS);
                    
                    // I NEED A WAY TO INTERRUPT THIS FOR LOOP WHEN USER PRESSES ABORT ON WEBPAGE
                }
            }
}

Thank you.
