MEMS (sensors)

I use the LIS3MDL Sensor: When I power the sensor and request via SPI the WHOAMI Register, the first answer is not equal to the default answer. When I send another byte to read the Register afterwards I get the default answer. Why is that so?

 data[0]=0B10001111; data[1]=0B00000000;data[3]=0B00000000; //this is not needed but i get the default answer here   SPI.beginTransaction(SPISettings(100000, MSBFIRST, SPI_MODE3));   digitalWrite(10, LOW);   delay(10);   for (size_t i = 0; i < datale...

interfacing lis3dsh with stm controller

Hi , is there any sample code for interfacing lis3dsh accelermeter sensor to stm32f103rb evaluation Board.Regards,manjunath

LIS3DH INT2_SRC is always 0 regardless of configuration. Pin does not trigger.

Hello,I am trying to setup INT2 pin on LIS3DH. I can successfully setup INT1 without any issues and confirm an interrupt has fired with INT1_SRC (0x31). I am trying to setup INT2 pin the same and confirm when it fires by reading INT2_SRC (0x35) but c...

Synchronise IIS3DWB sensors

Within a research project we are evaluating the IIS3DWB for measuring vibrations in hydraulic forging hammers for predictive maintenance.The current application requires that two IIS3DWB sensors (which are connected to the same microcontroller) are s...

Is there a C library for MMA8452 working with STM32L476RG?

In fact, I want to read the real time data MMA8452 working with STM32L476RG, I need to know if there is a C library that I can use in this case, if not, how i can develop a C library for this accelerometer giving the technical sheet.

Hello, how can I use the Pedometer function in Lsm6dsox. I have STEVAL-MKSBOX1V1. unico Gui cannot read my data in function pedometer. it shows me an error with regression tool. are there other variants so that I can configure my pedometer?

I am using the ISM330 for measuring Acceleration and Gyro data. Both are set to ODR=416Hz. The FIFO is used in Continues Mode with an ODR=416Hz. The Problem is, that sometimes the data in the FIFO seems to be shifted.

Is there a Problem when the Sensor is sampling and doing a i2c communication(reading the FIFO) in parallel?I saw that, that the FIFO gets shifted(or data is overwritten) a few times during collecting data.Can someone help me please?Best Regards,Chris...

220nF capacitor ESR LSM303AGR

It is stated that the 220nF capacitor should have a ESR smaller than 200mOHm. At what frequency is this rated? not sure what frequency the LSM is switching this capacitor. I had a look at the EVAL MKI72V1, but that one has an error in the BOM. Any su...

Does the IIS2DH allow for interrupt 2 to be used on the INT1 pin?

Hello I see that on page 39, on register six that the device allows interrupt 1 functionality to be used on pin 2. But is it possible for this to be done the other way?Thanks in advance, Dyfan
