you have the pictures on my previous post.

The pins are not soldered, but it's proper wired.

The ground and 5V is ok through the cable.

There is glare from the power LED in the pictures, so I can't actually see the solders on the RX and TX pins (MOSI and SS). At this point, I can't think of anything else other than a bad connection on RX/TX.

I give up.

I undo all my soldered joint, then I tried as a normal shiel. It worked (SEL 0 and 1 open) with the example sketch in arduino.

Then I closed SEL 0 and tried again wiht my usb to serail and couples of version of libnfc. Never worked.

I tried to do my soldering again for RX / TX... never ever worked.

Sorry to hear that. I have no idea at all what the problem might be. :(

Was Adafruit ever able to get this NFC Arduino shield working with libnfc in the adafruit lab? Before I spend any more time on this I am wondering if these instructions have worked for anybody.

I've read this entire thread, triple checked my connections to the FIDI. I have checked continuity and everything its in its specified place. I have made the recommended edits to the libnfc drivers, however nfc-list still times out. My FIDI has led's on the TX and RX I see 2 blinks of the TX light but nothing gets returned on RX. Monitoring /dev/ttyUSB0 shows that nothing is coming back from the nfc device.

Reverting my changes the board successfully can dump a card using the Arduino sketch. Known good FIDI, USB cable.

(Sorry to resurrect such an old thread but it seemed like everyone just gave up)

Sorry we've never used it: the shield is tested for I2C or SPI only. we suggest the breakout which is designed for the FTDI!

Hi all,

I know this topic is a little bit old now, but I wanted to share my results with the NFC shield v1.3 and libnfc (1.7.1 currently)

I followed the explanations of Jerome Bernard here : http://www.jerome-bernard.com/blog/2013 ... via-libnfc
I'm on ubuntu, so it doesn't matters if the article is untitled "... To a mac ..."

Here's the differences between my setup and Jérome's one :

- I use a FTDI breakout 5v from Sparkfun.
- The FTDI TX wire goes to the the SS pin on the shield
- The FTDI RX wire goes to the MOSI pin on the shield
- My shield is version 1.3 so I soldered SEL0.

And that's all :

Code: Select all

$ nfc-poll
nfc-poll uses libnfc 1.7.1
NFC reader: pn532_uart:/dev/ttyUSB0 opened
NFC device will poll during 30000 ms (20 pollings of 300 ms for 5 modulations)
ISO/IEC 14443A (106 kbps) target:
    ATQA (SENS_RES): 00  04  
       UID (NFCID1): a4  46  43  e7  
      SAK (SEL_RES): 08  
nfc_initiator_target_is_present: Target Released
Waiting for card removing...done.
