How-to
1

Hello boys
i try Platformio IDF and start lvgl
i have working project in Arduino
Exist steps to merge this ??

And please can anybody explain this example primary why arduinoTask too implement blink ???

#if !CONFIG_AUTOSTART_ARDUINO
void arduinoTask(void *pvParameter) {
    pinMode(LED_BUILTIN, OUTPUT);
    while(1) {
        digitalWrite(LED_BUILTIN, !digitalRead(LED_BUILTIN));
        delay(1000);
    }
}

extern "C" void app_main()
{
    // initialize arduino library before we start the tasks
    initArduino();

    xTaskCreate(&blink_task, "blink_task", configMINIMAL_STACK_SIZE, NULL, 5, NULL);
    xTaskCreate(&arduinoTask, "arduino_task", configMINIMAL_STACK_SIZE, NULL, 5, NULL);
}
#else
void setup() {
    Serial.begin(115200);
    xTaskCreate(&blink_task, "blink_task", configMINIMAL_STACK_SIZE, NULL, 5, NULL);
    pinMode(LED_BUILTIN, OUTPUT);
}
void loop() {
    digitalWrite(LED_BUILTIN, !digitalRead(LED_BUILTIN));
    Serial.println("Hello!");
    delay(1000);
}
#endif
