Ask questions and find answers on ST MEMS sensors, such as the LSM6DSV and the LSM6DSL. Learn how to use the SensorTile.Box, and STEVAL kits.
There appears to be a hardware bug on the LSM6DSM where if a sample is acquired while reading from the FIFO, then the pattern # becomes incorrect. I can consistently replicate this issue by reading at random intervals. Additionally, data on the FIFO ...
Hi,I'm currently using the FP-AUD-SMARTMIC1 package (https://www.st.com/en/embedded-software/fp-aud-smartmic1.html#:~:text=FP-AUD-SMARTMIC1%20is%20an%20STM32Cube%20function%20pack.%20This%20software,acquisition%2C%20beamforming%2C%20source%20localiza...
Hi,I have created a small function that reads out the 8-bit temperature register in the lis2dw12 sensor. The code is shown belowstatus lis2dw12::temperature(int8_t *temp) { *temp = static_cast<int8_t>(read_reg(REG_OUT_T)) + 25; printf("%d\r...
My LIS3DH is embedded on a PCB with gravity on Zh (upside down).It is configured with:ODR 10Hz, Z axis enabledNo filterFS @2HzIA1 on INT1Interrupt active HIGHAOI and 6D pos (for position detection)INT1 threshold set to 0x39 (around 0.916g)This config...
Hi! I’m using the LSM6DSLTR, and really just need to trigger an interrupt whenever the device rotates at a speed greater or equal to a given threshold. Do I need to set up any FIFO data, or is there a way to only generate an interrupt based on a ro...
I am trying to build custom boards using LSM9DS1, I shot through the data sheet, but the information on these two pins is not clear enough? What is the purpose of these pins(DRDY_M & DEN_A/G)?
I need to confirm what the ODR represents - the default ODR is 26667Hz. But what is the actual internal sample rate pre anti-aliasing filter (which must be implemented internally)?Assuming the actual Fsample is at least 26667, then ODR simply represe...
Hello fellow ST guys. I'm working with the LSM6DSO IMUs in my project. Nice chip indeed. Now I need to connect multiple IMUs and I need to synchronize them, so that I can read the data from all of those chips sequentially (asserting chip select pins...
Hi I have four questions please: 1- is there a new version of the UM2499 pdf manual, as most of the links are broken ? 2- I get this error with IBM watson IoT quickstart - (kCFErrorDomainCFNetwork error 2), i get this in different Iphones. As i thoug...
