How to connect and configure AMICAM(HW and SW: "microphone streaming") for recording 4 microphones ?
Hello,I have connected my amicam1 with the nucleo L476RG and 2 IMP23ABSU (from STEVAL MIC007V1) on respectively M3 and M4 of AMICAM1.I used the microphone streaming example ( from memsmic1 V5-6) and configure amicam1_conf.h with modifying AUDIO_I...
How to convert G to dbVrms
Hello Team,We would like to measure the vibration using LIS2DW12 (3-axis MEMS accelerometer), from the LIS2DW12 we were getting units in 'g' or 'mg'.Please let us know the possibility of converting g to dbVrms.Best regards,Abishek Devan
Resolved! Will the LIS2HH12 operate properly with Vdd_IO = 0V and Vdd = 3.3V ?
We are looking at using the LIS2HH12 in a design where the connected MCU is powered off and the LIS2HH12 remains powered on. We plan to use the LIS2HH12 in I2C mode so CS will be High. Will cycling Vdd_IO from 3.3 to 0 to 3.3V generate spurious I2C s...
Resolved! LSM6DSL vs LSM6DSR with (Acc/Gyro) INT1 issue
Hi, We have a PCB design which used to have LSM6DSL and we were using ACC/GYRO data from the sensor. Since we switched to the new LSM6DSR chip the INT1 does not trigger (when data is ready) anymore even though the sensor should be similar config (if...
Resolved! UNICO Pedometer Regression tool "cannot open regression_tool.config" and "cannot generate configuration file"
I'm trying to use the UNICO Pedometer Regression tool in offline mode to analyze accelerometer data from the LSM6DSO32 accelerometer. I have followed the instructions from the UNICO user manual regarding data format:-file name data_steps138.txt-data ...
Resolved! Adding new c and header files to a project? Also...what is that called?
I have a stm32f3discovery board and I want to start playing with the LSM303DLHC MEMS sensor.I seem to have found the original example code on github.So I guess I need to add both the header and c file to my project. I'm not sure how to go about this....
LSM9DS1 16G scale issue
Hello, We have found a non-expected behavior of the IMU system LSM9DS1 when is set with an accelerometer scale = +-16g. To show our findings, it is presented below descriptions and diagrams of the tests.Firstly, two different devices were tested to c...
Interrupt generation on INT2 pin of LIS3DH
Hello, I'm facing issues when enabling LIS3DH click interrupt, AOI1 and AOI2 interrupts on INT2 pin. These interrupts works fine on INT1 pin. Following is the flow I do to enable click interrupt on INT2 pin. register - 20h value - 119 //ODR 400Hz a...
