annotate Common/Inc/data_central.h @ 335:c11ce8c885d3 PressureMeasure_Improvment
Use average calculation for pressure: precondition was that pressure values jittered +- 10 HPa from one capture (once a second) to the other. Basically pressure is measured several times a second => using these values in an additional history calculation reduces the jitter down to +-1 per second
Additionaly a similar function has been added to the surface pressure capture to further reduce the jitter in long therm measurements (once a minute)
