hpacel —
hpacel* at acpi?
hpacel device driver supports accelerometers that
are commonly available in Hewlett-Packard laptops. The supported chip is
LIS3LV02DL from STMicroelectronics, although other
chips from the same family, such as LIS3LV02DQ, may
also work, provided that the vendor has implemented suitable
ACPI access methods.
The hpacel driver reports the acceleration
readings of the X-, Y-, and Z-axis via the
envsys(4) API and the
envstat(8) command.
STMicroelectronics, LIS3LV02DL: 3-Axis - ±2g/±6g digital output low voltage linear accelerometer. AN2381 Application Note, Revision 1, http://www.st.com/stonline/products/literature/anp/12441.pdf, June, 2006.
hpacel device driver appeared in
NetBSD 6.0.
hpacel driver only reports the readings from the
accelerometer via
sysmon_envsys(9).
