- * @brief Task that reads the DS18B20 sensors on two one-wire busses.
- *        The task can also be compiled with simulated sensors.
+ * @brief The FreeRTOS task to query the DS18B20 sensors on one or two
+ *        one-wire busses. Each bus must have only one sensor. That way
+ *        we don't need to care about the DS18B20 internal ROM address.
+ *        The task will update the DS18B20_State structure.
