Resolved! LIS3DSH, SDO Pullup Register

Hello,We have been using the LIS3DH for some time and recently acquire some LIS3DSH' as well.With both modules there is an internal pull-up for the SDO pin, and with the LIS3DH there is a register to control this pullup:CTRL_REG0I am not able to find...

Resolved! FSM compatibility with SFLP or tap detect in LSM6DSV?

I have four FSM programs working with the LSM6DSV sensor, all set to AODR/GODR of 30Hz in line with the examples I copied. Tap detect requires significantly higher ODR.  I might also want to run the SFLP at a rate higher than 15 or 30 Hz, so does thi...

LIS3MDL hard iron offset registers

 Hi, the datasheet for the LIS3ML does not mention any dedicated offset registers that can be used to deduct an offset vector from the measurements: However, when I view the LIS3MDL app note, it says they are there: The app note points to 05h through...

Resolved! LIS2HH12 working like 1.6kHz@ODR=800Hz

I am evaluating LIS2HH12. Before starting to collect data, I simply reboot it, set FIFO to stream mode (010), enable FIFO, and enable the sensor by setting ODR=800Hz (110). Then I collect 800 samples (each sample=6 bytes, 2 for each axis) by reading ...

[LIS2DUXS12] Set FIFO_MODE when using FSM

I had an idea to start recording accelerometer data in the FIFO by switching to FIFO mode at one point in the Finite State Machine. This would be done by setting FIFO_MODE bits in the FIFO_CTRL register by using the SETR command. However, in the an59...
