I have configured the LSM6SDM into continuous mode, 104Hz as is described in AN487, Example 1. I am reading first the number of words in the FIFO, and then the FIFO Pattern (from FIFO Status 3).Here are some code snippet for initialization:unsigned c...
I am attempting to use the LPF2 chain on the LSM6 accelerometers. The cut-off frequency is described as something like ODR_XL/100. I assume that means if you are running at 12.5 Hz the cutoff frequency is then .125 Hz. I am assuming that this is the ...
Hi,I want to configure the LSM6DSO to trigger an interrupt on INT2 when the device starts and stops moving. I used the following configuration, but I can only detect taps on the vertical axis: // LSM6DSO datasheet pg 74 // (00: stationary/motion-onl...
I am writing a driver to retrieve data from the I3G4250D gyroscope embedded in the STM32F411VE discovery board (MB1115D). When the sensor starts up, the first 1 second of data contains an invalid temperature value (typically showing -7). After one se...
Hi! We have been evaluating a few accelerometers from ST. So far we have seen reasonable results from H3LIS100 and H3LIS200 devices.However, H3LIS331DLTR is behaving contrary to our expectations.We have the H3LIS331DLTR device on a PCB, interfaced vi...
I am a nobe to these Mems sensor , i understood how to write the drivers of these sensors , setes its register to get raw values but i am unable to understand how to configure the internal settings of these sensors.like In Compass sensor we have to c...
From looking at the datasheet, by any objective measure, it appears the LPS22DF is substantially better.The datasheet shows the quoted 0.34 Pascal noise w/ ODR/9 bandwidth (LPS22DF) versus 0.65 Pascals w/ ODR/20 bandwidth (LPS22HH). However, a more ...
Hi,I using test library from ST:https://github.com/STMicroelectronics/STMems_Standard_C_drivers/blob/master/asm330lhh_STdC/examples/asm330lhh_read_data_pollng.cMy code is based to this code. and I can`t fugure out why Y is too small (and not shows ne...
we are performing accelerometer self test in production tester for measuring performance of sensor.software flow:reading x y z axis in 5 samples, clearing FIFO enabling self test. and giving settling time of 20ms delay. then taking 5 samples x y z ax...
Hello all,I have a question regarding the MEMS audio sensor MP23DB01HP. I managed to read out the Soundlevel of the sensor. But I don't know how to interpret this value. My question is, how can I convert the soundlevel to obtain a corresponding value...
