 /**
+ * CAN LCD.
- * CAN Test. This program sends a CAN message once every second. The ID of the

- * message is increased each time for testing purposes.
+ * This is the early version that only prints temperature sensor data.
- * Added LCD output

+ * TODO Fix more types of output: relay status, mail recieved etc.
+ * Make it configurable to use UART, because it's not necessary on the final PCB
