- * This driver tries to support the "digital" accelerometer chips from
- * STMicroelectronics such as LIS3LV02DL, LIS302DL, LIS3L02DQ, LIS331DL,
- * LIS35DE, or LIS202DL. They are very similar in terms of programming, with
- * almost the same registers. In addition to differing on physical properties,
- * they differ on the number of axes (2/3), precision (8/12 bits), and special
- * features (freefall detection, click...). Unfortunately, not all the
- * differences can be probed via a register.
- * They can be connected either via I²C or SPI.
