This library is for FRAM with I2C interface. FRAM has the following benefits when compared to Flash and EEPROM: Fast symmetrical read and write times (access time < 100 ns). (With I2C FRAM the speed is limited/determined by the speed of the I2C bus.) Random access at byte level for ...
I have the NTAG I2C plus Explorer Kit OM5569/NT322ER. I want to write the HEX data to NTAG I2C plus via the Cloud 3700 F usb reader and the windows app. I find 《NTAG_I2C_Demo》 can't do it. I need the windows apps support the usb reader and writting a-block bytes. Thanks....
