[eliezeroc]

Hello everyone;

I'm trying to develop a code to read and write in 1K tags but I'm not getting.

My project will make control of vehicles entering a parking lot.

Can anyone ajusdar me?

Thank you.

Hi Jorge_Gonzalez

I want to more some information about RFID reader.

I'm designing a full solution for warehouse management system, and knowing that NXP RFID solution is good choice.

Hello Eliezer Oliveira:

Thank you for using our community.

Please let us know more details about your issue:

Which NFC Reader IC are you using?

What type of tags you need to read?

Are you working from an existing software framework or code example?

What is the erratic behavior you see?

With this information we can provide better feedback.

Regards!

Hello Jorge Gonzalez, thank you for your attention.

1 - I am using MFRC522;

2 - I need to read Mifire tags 1K;

3 - I'm working with sample code.

4 - The code compiles without problem, but I can not read the tag, does nothing.

Already come some time working on it.

I'm using to communicate with the RFID module, the SPI0 PT60 micro controller;

If you need more information I have great pleasure in passing, and again thank you for your support.

Hello Eliezer:

Thank you for responding to my questions.

The MFRC522 initialization and the protocol used to communicate to MIFARE cards is kind of complex. That is why NXP provides the NFC Reader library. Unfortunately the library is currently available for some LPCXpresso boards such as LPC1769 and LPC11U68. Porting to a different MCU platform or using a third party sample code or stack is out of our support scope.

Sorry for the inconvenience.

Regards!
