Mock EEPROM¶
-
class
wscodec.encoder.pyencoder.eeprom.
Eeprom
(sizeblocks: int)[source]¶ A mock of the NT3H2111 EEPROM, based on a bytearray. There are methods to read and write from this in 16-byte blocks. Helper methods parse the entire EEPROM contents as an NDEF message. This mimics what a phone will do when it reads the NT3H2111 using NFC.
The EEPROM will normally contain the output of the cupl Encoder: an NDEF message containing one NDEF record. This itself will contain a URL. One of the parameters in the query string is ‘q’, which contains the circular buffer of temperature and relative humidity samples.
-
decode_ndef
() → ndef.record.Record[source]¶ Decode the NDEF message.
- Returns
First NDEF record in the message
-
display_block
(block: int) → bytearray[source]¶ Display one EEPROM block.
- Parameters
block – Address of the block to display.
- Returns
Block data as a list of 16 bytes.
-
get_message
() → bytearray[source]¶ Extract the NDEF message bytes from EEPROM.
- Returns
NDEF message bytearray
-
get_url_parsed
() → urllib.parse.ParseResult[source]¶ Parse URL in the EEPROM NDEF record.
- Returns
Parsed URL
-
get_url_parsedqs
() → dict[source]¶ Parse parameters in the query string
- Returns
A dictionary of URL parameters.
-
read_block
(block: int, blkdata: ctypes.c_char_p)[source]¶ Read one block into a pointer.
- Parameters
block – Address if the block to read.
blkdata – Pointer to an array of 16 bytes that the block will be read into.
- Returns
None
-
write_block
(block: int, blkdata: ctypes.c_char_p)[source]¶ Write one block from a pointer.
- Parameters
block – Address of the block to write
blkdata – Pointer to an array of 16 bytes that will be written to the block.
- Returns
None
