Hi All,

I am working with a LPS25HB sensor and am not able to get valid data out for the pressure or Temperature. Here is a register dump of my settings (tried 2 different settings):LPS25HB reg dump:0x08 , 0x0B0x09 , 0xA80x0A , 0x3F0x0F , 0xBD0x10 , 0x050x20 , 0x900x21 , 0x000x22 , 0x000x23 , 0x000x24 , 0x000x25 , 0x000x27 , 0x330x2E , 0xCF0x2F , 0x200x30 , 0x000x31 , 0x000x39 , 0x000x3A , 0x00LPS25HB reg dump:0x08 , 0xF00x09 , 0xA80x0A , 0x3F0x0F , 0xBD0x10 , 0x050x20 , 0xA40x21 , 0x000x22 , 0x000x23 , 0x000x24 , 0x000x25 , 0x000x27 , 0x330x2E , 0xCF0x2F , 0x200x30 , 0x000x31 , 0x000x39 , 0x000x3A , 0x00Here is the data I am getting out for the pressure sensor: <LPS25HB> Pressure = 0 hPa<LPS25HB> PRESS_OUT_XL = 248<LPS25HB> PRESS_OUT_L = 255<LPS25HB> PRESS_OUT_H = 255<LPS25HB> RPDS_L = 0<LPS25HB> RPDS_H = 0<LPS25HB> Pressure = 0 hPa<LPS25HB> PRESS_OUT_XL = 64<LPS25HB> PRESS_OUT_L = 0<LPS25HB> PRESS_OUT_H = 0<LPS25HB> Pressure = 0 hPa<LPS25HB> PRESS_OUT_XL = 226<LPS25HB> PRESS_OUT_L = 1<LPS25HB> PRESS_OUT_H = 0<LPS25HB> Pressure = 0 hPa<LPS25HB> PRESS_OUT_XL = 71<LPS25HB> PRESS_OUT_L = 1<LPS25HB> PRESS_OUT_H = 0<LPS25HB> Pressure = 0 hPa<LPS25HB> PRESS_OUT_XL = 214<LPS25HB> PRESS_OUT_L = 0<LPS25HB> PRESS_OUT_H = 0<LPS25HB> Pressure = 0 hPa<LPS25HB> PRESS_OUT_XL = 98<LPS25HB> PRESS_OUT_L = 1<LPS25HB> PRESS_OUT_H = 0<LPS25HB> Pressure = 0 hPa<LPS25HB> PRESS_OUT_XL = 191<LPS25HB> PRESS_OUT_L = 0<LPS25HB> PRESS_OUT_H = 0<LPS25HB> Pressure = 0 hPa<LPS25HB> PRESS_OUT_XL = 139<LPS25HB> PRESS_OUT_L = 1<LPS25HB> PRESS_OUT_H = 0<LPS25HB> Pressure = 0 hPa<LPS25HB> PRESS_OUT_XL = 6<LPS25HB> PRESS_OUT_L = 254<LPS25HB> PRESS_OUT_H = 255<LPS25HB> Pressure = 0 hPa<LPS25HB> PRESS_OUT_XL = 16<LPS25HB> PRESS_OUT_L = 255<LPS25HB> PRESS_OUT_H = 255<LPS25HB> Pressure = 0 hPa<LPS25HB> PRESS_OUT_XL = 200<LPS25HB> PRESS_OUT_L = 254<LPS25HB> PRESS_OUT_H = 255<LPS25HB> Pressure = 0 hPa<LPS25HB> PRESS_OUT_XL = 28<LPS25HB> PRESS_OUT_L = 254<LPS25HB> PRESS_OUT_H = 255Any thoughts or suggestions on what I might be doing wrong, or have setup incorrectly.Thanks,Eric #lps25hb
