Enumeration Type Documentation

sens_ProcessDef_t

enum sens_ProcessDef_t

State machine states for the sensor reading process.

The state machine is driven either by the sequencer (timer-based) or by direct polling via sensors_Start() / sensors_Work(). It progresses sequentially through the states; completion is signalled when SENS_DONE is returned.

Enumerator
SENS_BEGIN	Entry state: I2C is initialised and the sequence is prepared
SENS_INIT	Sensor initialisation: each active sensor is (re-)initialised if not already
SENS_START	Sensors powered on (xxx_On() called for the current group)
SENS_READ	Data read issued (xxx_Read() called for the current group)
SENS_STOP	Sensors powered off (xxx_Off() called for the current group)
SENS_DATAREADY	All sensor data collected; ready for post-processing or LoRa uplink
SENS_SERVICE	Service actions executed (e.g. SPS30 fan cleaning); data may be unavailable
SENS_END	Sequence complete: I2C is de-initialised for power saving
SENS_DONE	Final state: caller may read sensor data and schedule the next cycle

sensors_CayennelFromBckData()

uint8_t * sensors_CayennelFromBckData	(	uint8_t *	sizeOut,
		SysTime_t *	prevMeasureTime )

collecting sensor data into CayenneLppGetBuffer buffer for sending them via LoRaWan, the methods works with _bck_XXXXX sensor data, not with real.
The measure time is added only if time distance is bigger than 1min:

• UNIX - absolute time, if distance between times is bigger than 65353 minutes(45.5days), CayenneLppAddTimeMeasureABS

• relative, minutes 16 - max 65535 is distance is bigger than 255 minutes (4.25h), CayenneLppAddTimeMeasureMIN16

• relative, minute 8 - max 255, if distance between measured data is less than 255 minutes, CayenneLppAddTimeMeasureMIN16

Parameters

sizeOut	- the size(bytes) in buffer, the size is max 254, uint8_t is enough
prevMeasureTime	the previous measure time, 0 or NULL - is not specified, no time is added

Returns

address of buffer or null, if no data
