Using the LSM6 over SPI with the RP2040 Microcontroller for a mission-critical project (flight controller for UAVs).The SPI works well. Well in theory. In practice, 1 in every 20-100 reads returns corrupt SPI data (WHOAMI reads as 0x68/0x58). This is...
I have a question about the ADC sensitivity for the vAFE in the ST1VAFE3BX. Table 3 of the datasheet says that the input range is +-25mV when the gain is set to 16. With a 12-bit reading, this results in about 12 uV/LSB of resolution. However, the "A...
We observe mutually exclusive behavior in the LSM6DSVX driver:With interrupts DISABLED:Can successfully read raw values via sysfs: cat /sys/bus/iio/devices/iio:deviceX/in_accel_x_raw # Returns valid dataWith interrupts ENABLED:Sysfs reads return 0: ...
Hi,We are using 4 ASM330LHB in our application. We have placed 4IMU's on PCB. We put the PCB in temperature chamber to observe the sensor behaviour during the temperature variation(cooling) with 1deg/min from 30 to 60 to -20.During this test all sens...
Does the LSM6DSV support in-circuit firmware updates over SPI? If so, is there an app note that details how to do this. We are just trying to plan to support this in our new design if needed.
Hello Team,We are using the Qualcomm QCS6490 chip set running Android 13 on our custom board.As part of our project, we have integrated the LSM6DSOTR sensor, which is connected to the DSP pins via the I3C interface. Based on our discussion with the Q...
Hi everyone,I'm working with the LSM303AGR magnetometer using an STM32 microcontroller and trying to run the built-in self-test as described in the datasheet. However, the self-test consistently fails — the delta values (normal vs self-test mode) fal...
Hi ST experts, Is there any linux driver library available for LIS2DTW12? Where can I find the related information/document? Thanks.
Hello,I was wondering if it is possible to set the steval-mki109d with steval-mki245KA to standalone.I would like to test the ISM330BX what is happening when rotating. Thus I have set up a kit with a battery pack and I can start up the measurement wi...
Hi,do the STEVAL-MKI109V3 motherboard support STEVAL-MKI251A daughterboard or do I need the STEVAL-MKI109D Motherboard?STEVAL-MKI109V3 with FW 3.73.9 does not recognize STEVAL-MKI251A in my setup. Other daughterboards work just fine. /Ludvig
