Hi all, I developed a simple project with the MPL3115A2 sensor and I only need to detect little altitude differences.
I read in the application note that the manipulation of OFF_H register cause the sensor to be more stable reading small altitutes. I don't understand the reason for wich subtracting or adding an offset shuold give this result. My sensor continues to derive even if I set -127 to that register.
In my application I want only to detect altitudes between 0 and 40 meters, but the sensor still derive from the first sltitude mesurement.
Thus, I can't understand how can I correct offsets > 128 or <-127, using a register taht is only 1 byte in size. I could need greater offset.
