Functions
-
int confignfc_check()¶
Read the first block of NFC EEPROM user memory. Check if it contains an NDEF text record.
Configuration data are written as strings in the text record.
- Returns
1 if a short text record is present, otherwise 0.
-
int confignfc_parse()¶
Parse the NDEF text record into configuration strings. Writing configuration to NVM.
Configuration strings are formatted as:
<c:xyz>
Where:
‘<’ is the start character.
‘c’ is the ID.
‘:’ is the delimiter.
‘xyz’ is the value.
‘>’ is the end character.
The text record can contain one or more strings. There is no separator character between them.
Configuration strings are written to non-volatile memory with nvparams_write().
