The LIS3MDL is a 3-axis digital magnetic sensor, and it is true that the datasheet primarily focuses on configuring the output data rate (ODR) for the X and Y axes. However, the Z-axis is also configured when you set the ODR for X and Y.
The LIS3MDL datasheet does not explicitly mention a separate ODR for the Z-axis. Instead, the Z-axis operates at the same ODR as the X and Y axes when configured. However, the Z-axis might have different performance characteristics, such as power consumption and noise, depending on the selected mode.
If you are experiencing a slower sampling rate on the Z-axis compared to X and Y, there might be a few reasons for this:
- Configuration issue: Check your sensor's configuration to ensure you have properly set the desired ODR for all three axes. The ODR is configured in CTRL_REG1 (address 0x20) by setting the appropriate bits (ODR2, ODR1, ODR0).
- Data processing: It is possible that the way you are processing or reading data from the sensor is causing a delay in the Z-axis data compared to X and Y. Ensure that you are reading and processing the Z-axis data efficiently and without unnecessary delays.
- Sensor Behavior: While it is unlikely, there might be specific sensor behavior or a hardware issue causing the observed discrepancy between the axes. If you have ruled out configuration and processing issues, consider contacting the manufacturer or the community for further support.
In summary, the Z-axis ODR should be the same as the X and Y axes. Double-check your configuration, and data processing, and consider reaching out to the manufacturer or community for further assistance if needed.
