LSM303DLM datasheet by STMicroelectronics

LSM303DLM Frequently Asked Questions (FAQs)

• What is the recommended power-on sequence for the LSM303DLM?
  The recommended power-on sequence is to power up the accelerometer first, followed by the magnetometer. This ensures that the internal voltage regulators are properly initialized.
• How do I handle the case where the LSM303DLM is not responding or is in a faulty state?
  In case of a fault, the LSM303DLM has a built-in reset pin (RST) that can be used to reset the device. Additionally, the device can be reset by power-cycling the device.
• What is the maximum frequency of data acquisition for the LSM303DLM?
  The maximum frequency of data acquisition for the LSM303DLM is 10 kHz for the accelerometer and 80 Hz for the magnetometer.
• How do I calibrate the LSM303DLM?
  The LSM303DLM requires calibration to ensure accurate readings. Calibration involves applying a known magnetic field and adjusting the device's internal registers to compensate for any offsets or scaling errors.
• What is the effect of temperature on the LSM303DLM's performance?
  The LSM303DLM's performance is affected by temperature, with changes in sensitivity and offset over the operating temperature range (-40°C to 85°C). Temperature compensation may be necessary for high-accuracy applications.
