Hello
The datasheet reads "PN5180's default configuration after power-on is card mode to avoid collision with another RF field."
How to enable what is disabled by default? I want to count how many tags I have in collision and their UIDs. What are the registers, variables?
PLEASE in SPI pseudocode command.

Hello @AlanSbor ,
How to enable what is disabled by default?
- It is controlled by the firmware inside PN5180, please refer to page 78 of https://www.nxp.com.cn/docs/en/data-sheet/PN5180A0XX_C3_C4.pdf for details as below:
At start-up, the Autocoll state machine automatically performs a LOAD_RF_CONFIG
with the General Target Mode Settings. When a technology is detected during activation,
the Autocoll state machine performs an additional LOAD_RF_CONFIG with the
corresponding technology.
I want to count how many tags I have in collision and their UIDs. What are the registers, variables?PLEASE in SPI pseudocode command.
- There is guide based on NFC reader library , no SPI pseudocode command available, you have to reverse it by yourself. Please refer to https://community.nxp.com/t5/NFC-Knowledge-Base/Activating-multiple-Tags-using-NFC-Reader-Library/ta... and https://www.nxp.com/docs/en/application-note/AN12650.pdf for more details.
Hope that helps,
Have a great day,
Kan
