Here are the data structures with brief descriptions:

Cbar_bmp585_t	Measurement data produced by the BMP585 barometric pressure sensor. Populated by bar_bmp585_Read(); check IsDataValid before use
Cflash_at25CS_t	Configuration and state descriptor for one AT25EU0041A flash chip. Pass a pointer to this struct to every flash_at25_XXX function. Populate the IN fields before calling flash_at25_Init(); the OUT fields are filled by the initialisation routine
CLoraInfo_t
CmeasureDataNFC_t	Block of one measure data in CayennelLPP payload format The Data field contains the same payload as in LoRaWan processing, without UTC/TIME8/TIME16 fields, because the UTC time of measure is in UTCMeasureTime field
CmeasureNFC_t	Control block of NFC on address MEASUREDATANFC_ADDR where are stored the last measure data The EEPROM of NFC has 2kB, 2048bytes on address 128(MEASUREDATANFC_ADDR), max size for sensor data is 1920 bytes sizeof(measureNFC_t) is 16(SZ_MEASURENFC) fixed struct size - !!! the size my be boundary 4 !!! it is followed by measure data, on Data field measureDataNFC_t - circular queue
Cmems_DataBlock_t	Sensor data record stored as one element in the flash circular queue
Cmems_MainBlock_t	Master control block stored at flash address 0
Csens_GrpTiming_t	Definition for group of sensor sens_ReadingGrp_t the number of readings and timeout for reading data from sensors
Csens_processing_t	Sensor definition - interface
Csensor_t
Csleeper_t	Non-blocking timer utility – similar to HAL_Delay but without CPU blocking
CsystemParams_t	System configuration parameters – persisted in NFC EEPROM at address 0. The structure contains all modifiable variables/settings of system, can be read/writa via NFC tool or LoRa special read/write process The structure is 92 bytes (SZ_SYSTEMPARAMS) with a CRC8 byte at the end. Fields marked RO are written by the firmware; fields marked RW can be updated by a phone app via the NFC EEPROM or via LoRa special process
CsystemParamsRef_t	The references to systemParams_t for change values from server via downlink. The server sends via downlink the requirements for change of systemParams_t field, one by one. This struct is reference for finding the address of valid field in systemParams_t - its position and size:
Ctmphm_sht45_t	Measurement data produced by the SHT45 temperature and humidity sensor. Populate by calling tmphm_sht45_Read(); check IsDataValid before using Temperature or Humidity
CvalueChanger_t	Value-stability detector – determines when a periodically updated value has remained unchanged for a configured time window
