Resolved! Is the UNICO code open source?
LSM6DSLTR high current consumption
Hi,We found a problem with high current by using LSM6DSLTR.LSM6DSLTR is used to trigger system from sleep mode.The normal system sleep current is 0.5~0.9mA. The abnormal one becomes 3.25mA.This issue is related with this LSM6DSLTR IC. When we rep...
LSM9DS1 - Properties of the filters of the Accelerometer
The possible configurations of the accelerometer filters are clear:While the properties of those filters and what fields in the registers controls them is not clear at all.Ex documentation https://www.digikey.com/htmldatasheets/production/1639232/0/0...
Resolved! LSM9DS1 - how should I understand the fields of the CTRL_REG2_G (0x11) register
The datasheet on the LSM9DS1 chip on page 47 is very unclear on how the configuration of filters is supposed to work. They just tell that the fields INT_SEL and OUT_SEL are existing and give this diagram: I have hard time trying to understand what th...
lsm9ds1 minimal configuration
Hello,I have a very simple compass application which needs to poll the magnetometer, accelerometer and gyroscope roughly every 500mS (the board itself has no interrupt lines connected to the lsm9ds1), with the option of powering down for extended per...
The rotation matrix of sequence of calculation of roll pitch yaw
I am use lsm6dso with NUCLEO—F401RE board. I want to know what are the roll pitch yaw sequence of calculation. We can not transform body frame to naviagtion if we don't know the transformation matrix sequence.
Does LSM6DSR need to discard sample(s) when XLDA bit / GDA bit read value is b'1?
Dear SIR,I have found a polling mode reference code in the following linkhttps://github.com/STMicroelectronics/STMems_Standard_C_drivers/blob/master/lsm6dsr_STdC/examples/lsm6dsr_read_data_polling.cThe code demonstrates that after reading b'1 of XL...
LIS2DE12 and a buzzer on board
Hi, folks,I'm using LIS2DE12 on the PCB. The purpose: the device should inform the firmware, if the PCB has moved - intruder detection. I successfully programmed the device for INT1 on 6D movement. It works fine in general.On the PCB I have also a sm...
