Data Fields | |
| SensorLocation | loc |
| SensorTagList | tag_list |
| SensorContext | context |
| SensorPrecision | precision |
| errno_t(* | open )(struct sensor_t *sensor) |
| errno_t(* | read )(struct sensor_t *sensor, const SensorTag tag, void *buf, size_t *nbytes) |
The generic interface to interact with all sensors.
| SensorContext Sensor::context |
Data structure for the sensor to store context it needs between operations.
| SensorLocation Sensor::loc |
The I2C address and bus of the sensor.
| errno_t(* Sensor::open) (struct sensor_t *sensor) |
Function responsible for opening and setting up the sensor.
| sensor | The sensor who this open method belongs to. |
| SensorPrecision Sensor::precision |
What precision the sensor should measure. Can be changed between reads.
| errno_t(* Sensor::read) (struct sensor_t *sensor, const SensorTag tag, void *buf, size_t *nbytes) |
Function responsible for reading the data associated with tag from the sensor.
| sensor | The sensor who this read method belongs to. |
| tag | The tag of the data type that should be read. |
| buf | A pointer to the memory location to store the data. Should be large enough to fit the max_return_size bytes. |
| nbytes | The number of bytes that were written into the byte array buffer. |
| SensorTagList Sensor::tag_list |
A list of all the tags the sensor is capable of reading.
