Resolved! LIS3MDLTR Part Marking
Hello, I am looking for a part marking for LIS3MDLTR. The part says SF 233, but am unsure if this is the correct marking. I have read ST does not post their part markings externally.

LIS2MDL Magnetometer self-test
Hi there, The LIS2MDL Application Note (AN5069) states that the min and max values for each axis needed to run the self-test can be found in the datasheet. However, there is no information in the datasheet. The application note of the LIS3MDL, on the...
Resolved! Heading
Hi,Im using LSM6DSV16B & IIS2MDC for one of my project , how can i find heading using these sensor. Is there any library available for heading calculation?
LSM9DS1 SDO always 0
Hey folks,I've fabricated a little PCB to glue an LSM9DS1 to an ESP32-S3. As far as I can see, the ESP32 is sending the correct signals but the LSM9DS1 isn't returning anything useful. Here's what I get when I try to read 0x0F, the WHOAMI register, f...
lsm303agr magnetometer heading calculation
Hi, I am working with the lsm303agr e-compass. I am stuck with the hard iron callibration. I I wrote two functions fuctions for calculating the heading: I was trying to follow the https://gist.github.com/srlm-io/fafee8feed8bd5661266#file-hardironcali...
LIS3MDL hard iron offset registers
Hi, the datasheet for the LIS3ML does not mention any dedicated offset registers that can be used to deduct an offset vector from the measurements: However, when I view the LIS3MDL app note, it says they are there: The app note points to 05h through...
LIS3MDL temperature reading issues
LIS3MDL issues.Issue #1 - There are two 8-bit registers for temperature, and the datasheet says it's two complement, but I don't see any further description of the contents. Is it fixed point 8.8 or is there some division or offset that needs to be d...
LIS3MDL noise and maximum accuracy
In my system that found the heading angle using the LIS3MDL sensor, the maximum error value was 3 degrees using the ellipsoid calibration method. Also, although I used the sensor in low noise mode, I saw that the data in Matlab graphics was very wavy...
Resolved! LIS3MDL set/reset circuit
Hi,We were looking at the LIS3MDL sensor. Apparently it is a magnetoresistive sensor. When we examined other magnetoresistive sensors in the market we have seen that they need set/reset circuits in order to compensate for the disturbances in the magn...
Setting scale on LSM303AGR Acceleration sensor on STM32F411E Discovery board
Hello,As part of my master thesis, I am working with the onboard accelerometer of the STM32F411E discovery board. After day of effort I was able to find a code that would run without errors. It is one of the demonstration codes from f4 board master. ...
