# About
|
|
|
|
|
This is a manual test application for the MMA8x5x accelerometer driver.
|
|
|
|
|
|
|
|
|
|
# Usage
|
|
|
|
|
This test application will initialize the MMA8x5x sensor with the following parameters:
|
|
|
|
|
- full scale parameter set to +/-2 g
|
|
|
|
|
- 200 Hz output data-rate
|
|
|
|
|
|
|
|
|
|
To change these parameters, you can override them by setting their corresponding
|
|
|
|
|
defines in your build environment, e.g.
|
|
|
|
|
```bash
|
2018-10-29 17:07:35 +01:00
|
|
|
CFLAGS=-DMMA8X5X_PARAM_ADDR=0x1d make ...
|
2016-11-22 10:47:33 +01:00
|
|
|
```
|
|
|
|
|
See RIOT/drivers/mma8x5x_params.h for the default configuration.
|
|
|
|
|
|
|
|
|
|
After initialization, the sensor reads the x-, y-, z-axis values every 100ms
|
|
|
|
|
and prints them to STDOUT.
