| 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. |
