Hi All

MFRC522 is not reading tag. Help Me Please
Are there any healty running software?

Notes:
MCU Connections
Channel 1
MISO B9
MOSI B8
SCK B7
SS/SDA A4
RESET B4
Used MCU: DSPIC33EP128MC206 70Mhz External Osc

and

MFRC522 Osc Freq= 27.120Mhz

Investigating for you now.

In your program you set A8 to 0 and C7 to 1 with the comments GND and 3V3.

You're not powering the RFID module from I/O pins are you? If you are then the current from the pins is probably not enough to correctly power the module.

Hi Benj

3V3 and GND pins directly connected is Step Down Regulator outputs.
A8 and C7 ports not ussualy

Hi All
Is there a program that you know is working correctly?

SPI is made using the didin't work. RFID Card even when not plugged in, the read operation.

The Result
Card ID =0,0,0,0

(for MFRC522 reader with Flowcode 7.1.1.0)
Thank you

Hello,

I see you are using the CAL SPI component, what about instead using the MRFC522 component, there's an example here you can use.

Hello Benj

MISO,MOSI,CS,SCK and RESET signal is ok.

I think I found general problem.

I think that, MFRC522 board, can not produce antenna signal.

First possibility; MFRC522 board has corrupted.
Second possibity; It is not working, "Antenna ON" macros in Flowcode.

I'm going to buy new MFRC522 boards to electronic market in now.

I'm going to the share with you the results.

Hello Benj
RF ID card reader board has malfunctioned. I replace it with a new one. RF reading process has become can.

But as new problems.

ID CARD ID=99;103;99;106;62

testaddress[0]=99
testaddress[1]=103
testaddress[2]=99
testaddress[3]=106
testaddress[4]=62 not true


values should be;

ID CARD ID=(testaddress[0]); 80 ; 103 ;99; 106

testaddress[0]=????
testaddress[1]=80
testaddress[2]=103
testaddress[3]=99
testaddress[4]=106

Thanks for letting me know. I had a go at fixing this a while back but only ended up breaking the component completely.

I'll have another swing at it this week and see if I can improve things.

Hello Benj
Thanks for the answer. We look forward to the correct component.

This topic is a bit old but the RFID_MFRC522_v2 component now works well:

Using an Arduino and connecting: D9 to RST, D10 to SDA, D11 to MOSI, D12 to MISO and D13 to SCK.

The following flowcode reads and sends the key_id and the first data block of 16 bytes to the UART. Note that the documentation states that Check returns 255 if a key is present - but seems to return 0 and 255 if no key.
Also the interrupt pin doesn't seem to be able to be set so that an interrupt to occurs if a RFID tag is detected (which would be very convenient)
I use a dash of C to pull the RFID tag id (one line) - there doesn't seem to be another way to get this (first five bytes of block 0 store the key?)

Hi,

... still wrong card ID. The first and third nummer of the card ID are always the same

14:152:14:26:92
69:4:69:214:31
4:139:4:98:208

or is there something wrong in my flowcode?
