Atmel AVR4016
For example, a single call to the following initialization function for a gyroscope device
(which also supports temperature sensing) is all that is required to enable both
rotation and temperature measurement:
sensor_attach (&gyro_dev, SENSOR_TYPE_GYROSCOPE, 0, 0);
The same descriptor ( gyro_dev ) would then be used during subsequent calls to
either sensor_get_rotation() or sensor_get_temperature() .
7.8.1.3 Sensor read
temp_data.scaled = true;
// read values in degrees Celsius
sensor_get_temperature (&temp_dev, &temp_data); // temp sensor data
sensor_get_temperature (&gyro_dev, &temp_data); // gyro temp data
7.8.1.4 Use data in application
int32_t
app_temperature = temp_data.temperature.value;
uint32_t app_read_time
= temp_data.timestamp;
