Does Lis3dh need do calibration at when SMT in factory to our system ?
Hi, from Data sheet, i saw section 3.5, it says no need to further calibration but when i check output data from register 28-2D, the value is variety time to time , it has variety range for +- 20 ~ +-40, is it correct? or we should do calib...
Can several MEMS accelerometers be connected (in serie?) in order to reduce self noise
Hello allI am new at this forum and have almost zero knowledge in electronics but look at acceleration data on a daily basis (in the geophysics field).My experience is that MEMS accelero are quite noisy, especially at "low" frequencies (<~1 Hz).Just...
H3LIS331DL capture drop events
I am using an H3LIS331DL accelerometer on a custom PCB. I wish to use it to attempt to capture some drop events. Using an analog accelerometer, I have seen that the drop event occurs within approximately 1-1.5 msec. Will this accelerometer be able to...
Resolved! [Solved] LIS2DH12 Watermark and Overflow Interrupts at the same time (Not possible)
I'm working on a project that uses the LIS2DH12 accelerometer by ST. I have a couple of questions about it, and as it is quite a common part, I wonder if anyone here knows the answers:I would like to know if it's possible to activate two interrupts, ...
Using 3DoF magnetometer for position information
Our application would like to track the attitude of an object - yaw, pitch, and roll - at 500Hz update rate. The object is not moving very fast, but accuracy is important; for example, it would move through a 30 degree arc in about 1 second, and we w...
Resolved! Strange schematic for X-NUCLEO-53L1A1, I2C level shifter
Hi,X-NUCLEO-53L1A1 expansion board uses an IC (ST2329AQTR) to shift the 3.3V I2C bus lines of the MCU to a 2.8V I2C bus for the proximity sensor VL53l1x.Why are there these strange connections between the 3.3V and 2.8V bus as shown on the schematic o...
LSM6DS33 Temperature Sensor compensates the Gyro/Accel Sensitivity?
Hi thereWe use the LSM6DS33 mems and need to have accurate gyro data. As the LSM6DS33 has an internal temp. sensor I'm wondering if the gyro/accel sensitivity is automatically corrected by the sensitivity of +16 LSB/°C?We use the FIFO continous mode ...
Difficult to find values from
Hello ST, Am working on Steval-MK1159V1 Sensor which is interfaced through SPI to SAME51 Controller( Atmel ). I have been gone through Analysis of this Sensor. I Read LSM9DS1 Document. In Application, i read values of register which is 16 bit and mul...
IddPdn specification for LIS2DE12
I am designing a product for a client and have selected the LIS2DE12 for it's low power consumption. I have measured the power consumption (standalone), with nothing connected to it to be 160uA with VDD and VDDIO both connected to 3.0V. When I remo...
