ArgonKey sensor board

Overview
|
|
********
|
|
This sample provides an example of how to read sensor data
|
|
from the ArgonKey board. The result is displayed on the console.
|
|
It makes use of both the trigger and poll methods.
|
|
|
|
Requirements
|
|
************
|
|
|
|
This sample just requires the ArgonKey board.
|
|
The user may select or unselect the sensors from
|
|
:file:`samples/boards/96b_argonkey/prj.conf`.
|
|
|
|
Please note that all sensor related code is conditionally compiled
|
|
using the `#ifdef` directive, so this sample is supposed to always
|
|
build correctly. Example:
|
|
|
|
.. code-block:: c
|
|
|
|
#ifdef CONFIG_HTS221
|
|
struct device *hum_dev = device_get_binding("HTS221");
|
|
|
|
if (!hum_dev) {
|
|
printk("Could not get pointer to %s sensor\n", "HTS221");
|
|
return;
|
|
}
|
|
#endif
|
|

Sample Output
|
|
=============
|
|
|
|
.. code-block:: console
|
|
|
|
temp: 24.78 C; press: 101.448535
|
|
humidity: 43.000000
|
|
accel (4.121000 -6.859000 -5.384000) m/s2
|
|
gyro (-0.008000 0.270000 0.161000) dps
|
|
magn (0.021000 -0.552000 0.271500) gauss
|
|
- (6) (trig_cnt: 254)
|
|
|
|
<repeats endlessly every 2s>
|
|
|
|
In this example the output is generated polling the sensor every 2 seconds.
|
|
Sensor data is printed in the following order (no data is printed for
|
|
sensors that are not enabled):
|
|
|
|
#. *LPS22HB* baro/temp
|
|
#. *HTS221* humidity
|
|
#. *LSM6DSL* accel
|
|
#. *LSM6DSL* gyro
|
|
#. *LIS2MDL* magnetometer (attached to *LSM6DSL*)
|
|
|
|
The last line displays a counter of how many trigger interrupts
|
|
has been received. It is possible to display the sensor data
|
|
read for each trigger by enabling the **ARGONKEY_TEST_LOG** macro.
