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.

Re: NFC Shield for Arduino - PN532 & LibNFC
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.

Re: NFC Shield for Arduino - PN532 & LibNFC
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.

Re: NFC Shield for Arduino - PN532 & LibNFC
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!

Re: NFC Shield for Arduino - PN532 & LibNFC
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 :
