the accelerometer value exceed the scaling boundary after long time performance of the device.
I have developed a firmware in sensortile.box and I'm using accelerometer data(lsm6dsox imu sensor) for that specific application. The problem I encountered is that, scaling of the accelerometer automatically changed, because after the long time the ...
Resolved! H3LIS100DL: prevent interrupting sample to be overwritten/overrun
The H3LIS100DL has no fifo, and the ODR can be set to 400Hz. This would make it update the axes data each 2.5ms. I have programmed it to interrupt a mcu when a threshold is reached. This wakes the micro controller from deep sleep. Unfortunately it ta...
VL53L1-SATEL circuits question
Dear a ST engineer,I had purchased VL53L1-SATEL and evaluated the function with NUCLEO-F401RE and "VL53L1 Gui". I connected VL53L1-SATEL board to NUCLEO-F401RE board directly through some wires.However the GUI didn't recognize the connection of VL53...
Resolved! LIS2MDL Axis Directions
Figure 2 of the LIS2MDL datasheet shows the following picture of the magnetometer axes orientation. However, it's completely unclear if they are labeling the positive direction of the axes. If they did label the positive directions with the X/Y/Z lab...
Resolved! The ID value read by ism330dhcx chip is always 0
Hi, stThe MCU platform I use is nrf52840. The sensor uses steval-mki207v1. The hardware connection method is mode 1. The SPI mode of MCU is mode0, the frequency is 8MHz, and the bit order is MSB first. On this premise, no matter how many times I read...

LPS22HH reporting inaccurate raw pressure values
I am currently interfacing the LPS22HH component and have been encountering some very strange pressure data.Currently I am interfacing this in I2C mode and reading the pressure sensor values from PRESS_OUT_XL (28h), PRESS_OUT_L (29h) and PRESS_OUT_H ...
LSM9DS1 SDO not tri-stated
I need several LSM9DS1 sensors one the same SPI line. However, I noticed that when CS is high, SDO (aka MISO) is not tri-stated but pulled down to GND.I thought this was due to the default double-interface (SPI/I2C), so I have enabled the I2C_DISABLE...
Resolved! Need help in selecting an accelerometer for my application.
I want to ensure that the user fits our portable battery powered radar onto the back of a vehicle in the correct orientation. I want to monitor this using an accelerometer, I am considering using the LIS2DH12 but I'm not sure if this is suitable and ...
