ESP32 Arduino core supports FreeRTOS, which provides real-time operating systems (RTOS) functionality. With the use of FreeRTOS, ESP32 can perform multiple tasks simultaneously, making it a great choice for complex applications.
To use FreeRTOS with ESP32 Arduino core, you can start by including the FreeRTOS.h library and then defining tasks with the xTaskCreate() function. You can also use the vTaskDelay() function to add delays between tasks.
Here's an example code snippet to give you an idea:
```
#include <FreeRTOS.h>
#include <task.h>
void task1(void *pvParameters) {
while (1) {
// task1 code
vTaskDelay(1000 / portTICK_PERIOD_MS); // wait for 1 second
}
}
void task2(void *pvParameters) {
while (1) {
// task2 code
vTaskDelay(500 / portTICK_PERIOD_MS); // wait for 500 milliseconds
}
}
void setup() {
xTaskCreate(task1, "Task 1", 10000, NULL, 1, NULL);
xTaskCreate(task2, "Task 2", 10000, NULL, 1, NULL);
}
void loop() {
// Main loop code
}
```
In this example, we have defined two tasks (task1 and task2) that perform their own code and wait for a specific time using vTaskDelay(). We have then created these tasks using xTaskCreate() in the setup() function.
Note that when using FreeRTOS, you need to make sure that your code is thread-safe and does not cause any race conditions.
