NTAG I2C plus: How to read/write data over i2c?

donwasabi — Tue, 23 Aug 2016 13:53:45 GMT

Hi,

iam new to nfc and the NTAG I2C plus and want to read/write data over i2c from a microcontroller without any library.

Iam able to read and write bytes directly to/from the sram, but i don't know how to read/write data to/from tags, etc.

What bytes/commands do i have to send to the nxp device for doing so?

Many thanks in advance.

Hi,

We have provided LPC project for the NTAG I2C demo kit, it is a bare metal project, and you may refer to HAL_NTAG driver for details. The download link is http://cache.nxp.com/documents/software/SW309111.zip

Wish it helps.

Have a great day,
Kan Li
