Problem with Lsm6dsl via i2c.

Hi! I have a custom pcb with Lsm6dsl connect to mcu (nrf52832) via i2c. I can write and read regs of Lsm6dsl well (who I am also return 0x6a). But when I try to write ODR bits in CTRL1_XL (10h) reg (for example 0x10) then I can not work,because it a...

I am busy with the selftest LSM6DSL and trying to implement it, but I see your equation on page 115.... but is it not wrong? Or I do not get it offcourse.

What is the time required by the STLM20 between the application of supply voltage and valid Vout? My test results suggest 2ms but was hoping to see a published value in the datasheet.

Is there any pad example or Eagle library for the accelerometer LIS3DHH?. I would appreciate if someone can share the layout or the library, please. Best regards.

I am about to choose the IMU (6 axis gyro + acc) for my project.

The goal is to create the precise (and as cheap as possible) inclinometer, basing on the IMUs sensors. It should measure the angle change of the rotating wheel (speed up to 250 deg/s), with accuracy of 0.01 degree. I am not rejecting the fushion of f...

LIS2DS12 needs I2C pull up or not?

I am using STEVAL-MKI174V1 adapter board for LIS2DS12 evaluation. I checked the schematic of STEVAL-MKI174V1 and I have two questions:Can Vdd for STEVAL-MKI174V1 be 3.3V without damaging LIS2DS12 because it can handle only 2.2V (It seems answer to th...
