Resolved! MotionFX magnetometer calibration never finishes

I am using STM32CubeIDE with a STM32L471VET micro. I have included the MotionFX library and have 9DOF orientation output working, but I can't seem to get the magnetometer calibration completed. It continuously shows: MFX_MAGCALUNKNOWN even after 5 to...

On the LPS22HB SPI, what is the minimum high time for CS?

I'm communicating via SPI with an LPS22HB using an FPGA. Is there a minimum time specification between SPI transactions? I'm currently setting CS high for 0.5 SPC cycles between transactions, but this doesn't seem to work.

VL6180 always sending VCSEL Watchdog error

Hello,I was designing a board with a VL6180 and was surprised that the 0x4F register never uptaded to tell me that a new measurement was finished.So I looked at the 0x4D register to see that it answered me 0x19. Whitch mean I have a VCSEL continuity ...

Resolved! VL53L1CX (DocID031281 Rev 3) question about IOVDD & 2V8 mode XSHUT - needs pull up resistor or can it be direct connected to AVDD?

Question #1:In my system, I have 3.3V available, so I was planning to use that for AVDDVCSEL & AVDD since it is within the range but the I2C interface will run at 1.8V.The 1.8V seems fine from a Vih/Vil point of view. My concern is around IOVDD and 2...

FusionFX and quaternions - stationary drift

Hello, I'm using the FusionFX library(V2.5) to calculate quaternions and therefore estimate an object position. I'm using an X-NUCLEO-IKS01A3 that has the  LSM6DSO (ACC + Gyro) and LIS2MDL ( Mag). I'm using an 16G scale in acc and 2000dps in the gro...
