Hi ST
Now I am using ST25R3916B evaluation board, it works well with the project code you provided.
My final target is using 3920B on automotive for demostrating NFC card detection as well as digital car access to customer.
But we will finally change to other platform's MCU, not use ST's hsot MCU.
Due to our MCU has limited Fash / RAM size, we are considering to build our own middleware code to drive NFC frond end. but it looks like it's hard to understand the protocol through I2C waveform, and no any protocol document is avaiable on your website.
Is migating RFAL the only way I can do for realizing NFC function with 3916B / 3920B?
Thanks
Leo
