Handling Data Ready Interrupts for ASM330LHHXG1 in IMU Array Application

[eds]

Hello everyone,

I am currently developing an IMU array application using the ASM330LHHXG1 sensor and am trying to streamline my interrupt management. This sensor has two interrupt pins, and I am contemplating whether to use both pins or just one. My primary concern is with the Data Ready (DRDY) signal, which indicates when new data from both the accelerometer and gyroscope are available.

Does anyone know if the DRDY signal from this sensor is synchronized for both accelerometer and gyroscope data? In other words, does one DRDY signal mean that both sets of data are ready to be read simultaneously? Additionally, I’m considering whether to assign each sensor type (gyroscope and accelerometer) to a separate interrupt pin or to use one pin for both.

Could using two separate interrupts improve performance in any way, or would it be overkill for standard motion detection and tracking applications?

Any insights or experiences shared would be greatly appreciated!

Thank you in advance!
