Posted on August 07, 2016 at 13:03Hello,1.according to section 2.11 Temperature sensor :should i read both OUT_TEMP_L (0Ch) & OUT_TEMP_H (0Dh) ?the data is stored only in OUT_TEMP_H (0Dh) ?2.the data i get using OUT_TEMP_H (0Dh) is too low (10C-13C)...
Posted on August 05, 2016 at 23:23Hi 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 ,...
Posted on August 04, 2016 at 10:48HTS221 after read all humidity registers final value always 29.0% and not changed in time. All data register contain 0xAE values. ST firmware driver for HTS221 also returned 29.0% and 0xAE registers values. Connecti...
Posted on August 04, 2016 at 11:54Hi,I'm working on lsm9ds0 and spi with a stm32f4. The accelerometer and gyroscope work successfully on my device but since a few days, the magnetometer seems to get random values. For test, gyroscope is in power dow...
Posted on July 30, 2016 at 18:46I have a problem with the accelerometer noice, I feel that 100mg noise for the mode 2G, 10 Hz-Normal, BDU, HR (12bits) is way too much. In my setup I use your STEVAL board on an idle table without any vibration doing ...
Posted on July 27, 2016 at 07:20Hi,I try to get power consumption about 10 uA using LIS331HH in low-power mode (power supply voltage 3V). But I've got 23 uA average power consumption in low-power mode (0.5 Hz data rate).Working cycle: sleep (power c...
Posted on July 19, 2016 at 21:08I try to turn off the accelerometer by SPI commands to use only 1uA according to the spec. I have not found any SPI commands to turn it off to reduce power consumtion to about 1uA, everything I tried still needs abou...
Posted on August 02, 2016 at 09:55Hi, For a solution we want to use the LPS25HB in a liquid environment. In our opinion, the best way to do this is by installing the sensor in an oil filled case with a thin metal membrane on the top. On this way the...
Posted on July 26, 2016 at 06:19Should my program get 1000 mg when F3 Discovery Board is in steady state on a horizontal surface? Measurement range = [-2g;+2g]; Linear Axeleration Sensitivity = 1mg/LSB; High Resolution Mode I get 15344 mg (0x3BF0) a...
Posted on April 22, 2015 at 09:20We use an L3G4200D rate-gyro in our project.Part of the setup involves acquiring calibration data from the sensor (zero-rate drift versus temperature as reported by the sensor itself).After applying the collected cal...
