Hi, stNow I've found some new problems.Sometimes the value read from who AMI register will be 0x48. After finding this problem, I suspect that the connecting wire is unstable. After replacing the DuPont wire, the value read back to normal (0x6b). I ...

Hi, stThe MCU platform I use is nrf52840. The sensor uses steval-mki207v1. The hardware connection method is mode 1. The SPI mode of MCU is mode0, the frequency is 8MHz, and the bit order is MSB first. On this premise, no matter how many times I read...

Hi，Eleon BORLINIThe current situation is that if the parameters are written into CTRL1_OIS and CTRL3_OIS registers by the auxiliary SPI bus, the parameters read by the auxiliary SPI are still the default values, and the parameters read by the primar...

Hi，Eleon BORLINII have understood what is written in the datasheet. Under mode 1, the maximum sampling rate of the accelerometer can only reach 833hz. In order to reach 6667hz, mode 4 must be used.Do you have any routines related to mode 4 using inte...

The current configuration status is as follows/* Start device configuration. */ ism330dhcx_device_conf_set(&dev_ctx, PROPERTY_ENABLE); ism330dhcx_device_conf_get(&dev_ctx, &rst); // if (rst != PROPERTY_ENABLE) // TODO Define return ...

By the way, we only need to collect acceleration data, but the demand for sampling rate is relatively high. What's your suggestion.That's why I ask you, the accelerometer ODR can't be set to 6667 Hz.

I use the SPI protocol. Interestingly, I find that when I use an external oscilloscope to detect SPI waveform, I will receive different ID values. Otherwise, it will be the normal value of 0x6b. Can this phenomenon indicate that ism330 is vulnerable ...
