Hi,

I want to build an altimeter using LPS331AP sensor and after reading AN4159 I discovered that I should have software filter to have an accuracy of 0.02 mB required for altimetery. Do you know where to download such filters?MCU L�fter #lps331ap

Hi.

I got the same problem. I found how to get TCV1, TCV2 etc, but still can't calculate correctly pressure correction values. I want to use this sensor for my weather station project, but found that pressure variation over temperature change is too high, especially at minus temperature. e.g: -10C => 1001hPa, -16C => 1002.3hPa with the same actual pressure.It's very strange what software filter is not available through this website; it was mentioned in AN4159, but even registers addresses are not mentioned any available documents.Does anyone have such information? Can share please?Yury.
