void vTask1(void *pvParameters) {
  while (1) {}
}
void vTask2(void *pvParameters) {
  char *pcVariable = (char*) pvParameters;
  while (1) {}
}

int main() {
  xTaskCreate(vTask1, "Task 1", 1000, NULL, 1, NULL);
  // 1 .. Task Priority from 0 - configMAX_PRIORITIES - 1
  // 1000 .. Stack Depth

  const char* paramForTask2 = "Some text";
  xTaskCreate(vTask2, "Task 2", 1000, (void*) paramForTask2, 1, NULL);

  vTaskStartScheduler();

  while (1);
}
