Reply To: Configuring PN512 correctly

[Justin Nguyen]

Dear,

I got same problem here with NXP PN5120 which is currently working perfectly with LPC1769.
when running with NfcrdlibEx4_MIFAREClassic and NfcrdlibEx1_BasicDiscoveryLoop.

However, when integrate the PN5120 with Nucleo STM32 F030R8. I could not read the tags, the DiscLoop_run method always return NoTechDetected (refer the Poll_Mode in Discovery Loop).
I have no clue what is going on and how to solve the problem.
Anyone has any idea?

The code has been ported from NfcrdlibEx4_MIFAREClassic example with follow steps:

• Disable macro RTOS & PH_PlATFORM


• Compile the ReaderLib with SW4STM32 IDE.


• Base on STM sample project & SW4STM32 IDE, link to the ReaderLib.


• Port NfcrdlibEx4_MIFAREClassic.c, all the flow for Rc523 are retained, remove others HAL e.g 663, 5180


• Implement my own STM32 phbalReg, especially the Exchange method.

The SW run perfectly, the sequense commands are same with NXP sample.

• PN512 version return successful (0x82) when sending 0xEE (address 0x37h) 0


• TxControlReg return 0x80 which are same as Datasheet.


• However, tag can't be detected

Other question
Do we really need SetInterupt() function in NfcrdlibEx4_MIFAREClassic.c, I remmove the method and tags still can be detected using the LPC1769?
