Read/write to NT3H1101 nfc chip?

[aylee4]

Is there a way to write to this ntag using i2c interface on an arduino and/or analog discovery 2's program Waveforms?

I am using NT3H1101 nfc chip.

Hello,

Please take a look at table 6 of the data-sheet where the memory map from the I2C interface is shown, this way, you will have a better understanding of the block addresses to access from I2C.

Also, please refer to chapter 9.6 for correct Adressing of I2C.

Data-sheet:

I hope this helps.

Regards,

Ivan.

Thank you! I have been referring to the memory pages in the datasheet.l and I do better understand.

I am trying to hardcode plaintext. I am having trouble with writing although i can easily read any of the memory blocks I want.
