Resolved! DTS configuration for LIS2DW12
Hi,I am trying to figure out how to determine the reg=<0x??> value for the LIS2DW12. From the example page they have 0x6b but for a different device. I cannot figure out what this value needs to be.Thanks&i2c2 { status = "ok"; #address-ce...
LIS2DW12 not recongnizing movement
Hello , I am working with accelerometer LIS2DW12, when I move the device very very slowly I do not see that an INT1 interrupt being raised. However, when I move the device in regular speed I DO see the interrupts. Can you tell me why is that?(the mov...
Resolved! Configuring the Meta classifier whith UNICO
Hello,I'm working on an ultra low power application where the MLC of the LSM6DSO32X is used to wake up the mcu when interesting stuff is happening, in particular I implemented two decision trees, each one focused on the detection of a pattern.In orde...
Digital MEMS microphone used for sound pressure level measurements
Hello everyone,I'm interfacing a digital MEMS microphone with a stm32l152re mcu cortex M3 using I2S with DMA In order to measure sound pressure level. the communication is based on acquiring PDM ( Pulse density modulation) values that represents the...
STEVAL-MKI159V1 with Nucleo F446RE - I2C
Hi, it's my first experience with MCUs in general.In this first approach I try to read outputs from MKI159V1 (LSM9DS1) with the nucleo F446RE. I'm starting with I2C protocol. I read any kind of articles here in the community but I still can't work it...
H3LIS331DL: Getting terrible readings
I'm experimenting with this accelerometer and I'm having some very disputable results while the device is sitting still.I'm using ST's library code, but I will detail what I am doing here:h3lis331dl_full_scale_set(&dev_ctx, H3LIS331DL_100g); h3lis331...
Corrupted Data on the SD card from STWINK HS Data Logger
Reducing the number of sensors enabled in the configuration file helps, as does slowing down the SD clock (i.e. increasing hsd1.Init.ClockDiv = n in STWIN_sd.c). We've also noted that the code in sd_diskio.c has the compile time build define "ENABLE_...
Resolved! How to put lis2dw12tr in power down?
Hi im using lis2dw12tr sensor with I2C protocol in my app and i configured sensor in powerdown CTRL1 register i writed 0x00.But i see that on the board on which sensor is placed has current consumption around 370uA. On the board with unmounted sensor...
Question about IIS3DWB INTERNAL_FREQ_FINE register
Hello, I’m using the IIS3DWB with an Arduino Portenta, using a procedure similar to Kris Winer’s github (i.e. using the FIFO buffer in continuous mode, 256 watermark, stop on watermark, data ready interrupt on watermark, running various cycles until ...
