Regarding the LIS2DW12 and LIS2DTW12 devices, there is no published specification on the accuracy of the ADC sampling frequency in the datasheet, nor it's drift against temp and supply voltsage. Without these data the selected ODR is a guess, e.g. 40...
I am using IIS2DH accelerometer for vibration analysis. As per the datasheet the Zero-g level for x and y axis is 0 while z axis measures 1g. For my application when the device is resting x and y shows zero but z shows the value which give wrong read...
I have been reading a 780 samples from lsm6ds3 FIFO via i2c (i2c_dev driver from linux) but the read is taking arround ~1.5 to 2 sec. this seems little unusual to me . is there any way to reduce the i2c read time ?.Here is my read function:static int...
I need help with the vl53l0x sensor and stm32f103 board if anyone can help me with programming or any library.
HiWe are testing the LPS22HH on the MKI192V1, and we have got the pressure and the temperature. We also convert the pressure value to the height.We put the LPS22HH in the metal shell, and It is not sealed. We use air guns to heat the shell, and we fi...
After upgrading the firmware to 'ProfiMEMSToolV3.6.4.dfu' using DfuSE, the blue LED on the board doesn't turn ON and it doesn't show up under any virtual COM ports in my laptop. Attached screenshots. Where am I going wrong? How can I debug this? NOTE...
Hi Guys,I encountered a very strange problem and hope you can give me some suggestions!The LIS331 is adopte to measure device tilt, we assembled the PCBA in vertical positon and this means the sensor also works at vertical status. Please see the atta...
Hello,I'm struggling with LSM6DSM readout and would like to ask for some insight. I use a custom board with 7 other I2C sensors and the LSM6DSM is the lost one I need to handle. Among them is a H3LIS331 from ST.For all of them I use the same code for...
Hi,I'm Looking for a suitable design pattern to reliably handle interrupts from the embedded functions, i.e. pedometer, tilt and significant motion.Kind regardsJerker
I have configured the part to do 8 bit reads of Acceleration and Gyro. Using the FIFO in continuous mode with a watermark of about 1700. I am using I2C interface.First I determine the number of words in the FIFO.Read both the high and low bytes of th...
