When driving these two sensors with nordic's bluetooth chip, I want to obtain the relevant attitude angle through the motionfx library, but the program has been stuck in the initialization of motionfx. If the MadgwickAHRSupdate algorithm is used, the...
I'd like to know what the differences are between the VL53L1, L3 and L5 from an optics and SPAD array perspective. From this question (https://community.st.com/s/question/0D53W00000EmGT5/i-want-to-implement-lidar-using-multiple-vl53l3cx) it seems lik...
Hello, I have developped a product using VL53L1X last year, and recent communication from STM suggest there is an improvement in detection in a new product, VL53L1. I wonder if this is exactly the same product with only software improvement (hence I ...
Hi,so a few months ago I wrote a program to read values from LIS3DSH sensor. It was working good until last week Z axis stopped working, and this week Y axis also. It always sends back 0x8080 values, while X axis is still working great. I have a cust...
Hi,I use STM32F4 with BMI160. But i have a problem. I cannot initiate BMI160 so I can not get gyro and accel data. You can see here my init functions:"init_sensor_interface();bmi160_init(&bmi160dev);init_bmi160_sensor_driver_interface();"When i write...
Hello ,Is it possible to connect the senor-borad STEVAL-BCN002V1B direct with our computer, if the computer has Bluetooth 5.0 standard. Or do I need an bluetooth extension board for my nucleo board.The aim is to read out the sensordata from the board...
We've just changed the way our system is powered: Previously the accelerometer was powered from a 1.8V regulator, now it's powered directly from a 3V coin cell (schematic part attached).With the change, we have started to observe a strange ramping wh...
I'm trying to configure a LIS3DH to trigger INT1 after filling FIFO, after which I want to read out everything over I2C and then repeat.I've gotten it to work (at f=10 Hz, I get INT1 interrupts at the expected ~3 sec interval), but when I read out th...
Hello,I am trying to use an LSM6DSOX through SPI communication, but I am having some problems due to the length of the cable. I'm using a cable about 2 m long but the sensor is not working well. I have tried using different LSM6DSOX chips but the res...
I started to evaluate LPS22HH using STEVAL-MKI109V3, STEVAL-MKI192V1, Pressure LPS22HH Kit, and Unico-GUI. Of the 4 STEVAL-MKI192V1 I purchased, the atmospheric pressure of 2 devices shows strange temperature changes.LPS22HH press =4.3268t+879.71[hpa...
