North heading using LSM303AGRTR

Hello,I am using LSM303AGRTR in a custom board.After collecting X(68,69 reg),Y(6A,6B reg)and z(6C,6D reg) values, I want to know how to calculate angle with respect to north ?(z axis is perpendicular to earth surface)Also if the IC is given 90deg til...

Muxing MP34DT05-A signals with another component

We are hooking up MP34DT05-A (showing SPK mic in the diagram) to GPIO pins of our processor configured for PDM clock and PDM data from the mic. The power supply to this mic is gated by an Enable signal from a GPIO from the same processor. The mic is ...

Can PCB design (not following all guidelines) really affect the performance (precision) of the LPS25HB sensor when using it at highest precision ? Can the LPS25HB works properly at best precision without vent aperture ? in a waterproof ip65 case ?

Hello, I work on a wearable solution with your pressure sensor LPS25HB. I have a problem with the precision of the sensor. Using the LPS25HB adapter board (STEVAL-MK1165V1), I have sufficient precision to detect a high difference of 50cm (I use the b...

Maximum I2C frequency for VL53L1X?

In DocID031281, Revision 3 of the datasheet it says 400kHz. IIRC, in an older version it said 1000 kHz.It was my understanding that the VL53L1X and VL53L1 are the same part but the data processing has been moved from the sensor (VL53L1X) to the host ...

IIS2DLPC vs LIS2DW12

The datasheets for the IIS2DLPC and LIS2DW12 appear virtually identical beyond the title pages. What is the difference between these two part numbers?

LSM6DSO pedometer threshold/offset settings

I have one axis on the LSM6DSO that gives a lot of false positives due to some vibrations on the board. I know there is a way to set the step count and duration thresholds, but is there a way to adjust the sensitivity or motion threshold of just one ...
