Wrong LCD refresh condition #7

Closed gaborsimon closed 8 years ago

Regarding DHT22 data the refresh condition is not correct. Currently it is: if (Signal_RELIABLE == XDHT22_DATA_QUALIFIER)

With this statement the data is refreshed in every cycle that is not good. DHT22 has to provide a flag that signs if new conversion is done and LCDManager has to update the display only in this case. Qualifier check has to be performed within this condition.

Additional todo: in case of first run "--" data has to be written to the display.

This issue is already solved with the new DCF77 sensor handling and new scheduling.
