STLM20W87F Output Values Do Not Change

Posted on June 08, 2017 at 04:31Hello:I am using the STLM20W87F temperature sensor in an application, basically, on a PCB to measure ambient temperature.Referring to page 10 of the datasheet, I have the sensor connected with a filter of 1000p / 10K....

LIS2DH12: Interrupt issue with click configuration

Posted on June 07, 2017 at 23:23Hi everyone,For my application I used the LIS2DH12 MEMS in single click configuration. This is my setting:CTRL_REG1 = 0x5F                       // ODR=100Hz, Low Power mode, Z Y X axis enableCTRL_REG4 = 0x00         ...

Accuracy FlightSense

Posted on June 02, 2017 at 11:05Hi everyone !I'm working on the flightsense sensor thanks to the expansion  board X-Nucleo-6180XA1 and a satellite on a STM32F401RE. And I have some questions :I would like to know the accuracy of the sensor ?Also, I ...

Continuous Range measurement VL6180x without API

Posted on June 07, 2017 at 15:08Hey,I am trying to use the VL6180x without an API and want to communicate to it directly by I2C. Therefore I use the USBISS. Performing measurements with single shots works fine. I can also read out the results easily...

L3G4200D - STATUS_REG and Spykes

Posted on June 05, 2017 at 11:40Hi,reading data from L3G4200D i observed some spikes.So i set the BDU :I read before MSB and then LSB for X, Y, then Z such as described in the datasheet.reading the status_reg to know when new data is available i saw...

Can I use LPS25HB to measure the pressure of foot stroke

Posted on June 01, 2017 at 13:56Hi All,I wanted to use LPS25HB for measuring the pressure of foot stroke while running. Can this sensor be used for the same. Is this activity realizable using this sensor ?. I checked the datasheet and it said it is ...

LSM303AGR mems reading problems.

Posted on May 30, 2017 at 11:39I'm working on LSM303AGR mems and I've some reading problems: when I read x, y, z accelerometer registers in 'normal mode' I get lots of 0 and sometimes a correct value (z value have to be about 1G, not 0), when I set ...

LIS2DH12 communication problem

Posted on May 29, 2017 at 11:13Hello, I am using two LIS2DH12 sensors in my project. I am using I2C communication interface. The one with the address pin high (IC4, address 0b0011001x) is working OK, but the one with the address pin low (IC5, addres...

LIS3DSH question and documentation request

Posted on March 31, 2017 at 07:49I've been able to get the LIS3DSH working for single values by doing this: transmitData[0] = (uint8_t) (LIS3DSH_READ | LIS3DSH_X_L); SPISend( transmitData, receiveData, 2); xl = receiveData[1];But if I wanted to read...
