About ASM330LHH STATUS_REG

Please tell me about the STATUS_REG for ASM330LHH. I'm using SPI communication. A similar question was posted earlier, but the situation is slightly different.

When I ran the same program on 30 board-mounted samples, 29 of them showed a change in STATUS_REG within 400ms after the ASM330LHH setting, but one remained 0 without any change.

I'm guessing from this that is not a sowtware problem, but I would appriciate a list of possible factors as the cause.

Hi @ggob ,

The STATUS_REG indicates new accelerometer and gyroscope data availability. If one board shows no change, possible causes include hardware issues (sensor damage, poor SPI connection, power problems), SPI communication errors (wrong settings, signal noise), incomplete sensor initialization, or the sensor being in low-power mode. I recommend checking SPI signals, power supply and comparing initialization across boards to isolate the issue.
