Currently in one of my applications I use the PN5320 to make the card reader to manage access.
For cost reasons, I want to switch to the PN512 model.
It's been a week since I try to make it work in the same way as the PN5320 (AutoWakeUp during a card detection and reading the data to have the ID tag).
For the moment, I manage to launch the Polling however when I present a card, nothing happens (no exchange with the oscilloscope), nothing in the data, nor of interruption.
My configuration code is as follows:
temp = readPN512(TxControlReg);
if (!(temp & 0x03))
Do you have simple configuration examples to simply read tags?
In addition, when I want to put it in AutoWakeUp mode, I have continuous polling mode.
I believe it will be helpful to start with the evaluation board and then move to a custom solution, please refer to the following link for the eval board: PN512 reader board | NXP
Regarding the SW, there is a reader library for PN512 available in the Software section of the link previously provided; Documents and Software -> Embedded Software -> NFC Reader Library.
Hope it helps.
To clarify, when I make the following commands (sends data in Fifo and TRANSCEIVE mode), I do not observe any data sending on the 13.5Mhz signal.
