[ujwal_kumar_N_L]

Hi community im currently working on NFC module RC663 PLUS ,with LPC55S69 microcontroller .
Problem :

1. How to Activate LPCD mode ,I'm currently working on Polling mode .
2. There is continuous interrupt been generated ever 2ms for polling ,how do I modify this ??Its consuming a lot of power.
3. How to generate IRQ if the card is placed is it possible??

Details :

1. Board LPC55S69
2. NFC-CLEV663 PLUS front end module
3. Using SPI
4. Using polling method

I have attached the current code im using ,please let me know how do i modify this from polling to LPCD mode and also create IRQ when card is detected.

Thank you and regards

Hello @ujwal_kumar_N_L

Hope you are doing well.

Discovery Loop from the NFC reader library may only be designed for POLL mode.

Perhaps you can take a look at the LPCD example from the NFC reader library (NfcrdlibTst12_Rc663Lpcd) and refer to the following articles:

• Using NFC Reader Library with LPC55S69
• Porting NFC Reader Library to the i.MX RT and Other MCUs
• NFC Reader Library Porting FRDM_K64F

Regards,
Eduardo.

Hi,

NfcrdlibTst12_Rc663Lpcd example project is included in the NFC Reader Library. You can download the library corresponding to your device from the Downloads section of the webpage:
