|
### simple.c
|
|
Basic example of how to use this device
|
|
|
|
### fifo.c
|
|
Instead of polling for every single [x y z] set, a FIFO with programmable capacity ("watermark") can be used, and then dumped into memory once full.
|
|
|
|
All FIFO readings use 10-bit resolution regardless of the mode set in `lis.cfg.mode`.
|
|
|
|
The watermark level can be adjusted to a value [0-31] by modifying the `lis.cfg.fifo.fth` property before calling `lis3dh_configure()`.
|
|
|
|
The LIS3DH can optionally apply a HP filter on the sample data. It can be used to greatly reduce the "DC acceleration" present.
|
|
|
|
### interrupts.c
|
|
This device supports two different interrupt "output pins," `INT1` and `INT2`. The appropriate flag must be set in either `cfg.pin1` or `cfg.pin2` and the interrupt source must be configured to trigger into `INT1` or `INT2`. This file contains example code that listens and receives an interrupt when the FIFO watermark is reached i.e. it is full.
