specified temperature in the config file.
## Adxl345 Accelerometer Commands
The following command is available when an "adxl345" config section is
enabled:
- `ACCELEROMETER_MEASURE [CHIP=<config_name>] [RATE=<value>]
[NAME=<value>]`: Starts accelerometer measurements at the requested
number of samples per second. If CHIP is not specified it defaults
to "default". Valid rates are 25, 50, 100, 200, 400, 800, 1600,
and 3200. If RATE is zero (or not specified) then the current series
of measurements are stopped and the results are written to a file
named `/tmp/adxl345-<name>.csv` where "<name>" is the optional NAME
parameter. If NAME is not specified it defaults to the current time
in "YYYYMMDD_HHMMSS" format.
