Hi, I recently purchased your product (x2) from a local distributor. After soldering all the points, I connected the NFC shield and Audruino Uno to the computer and tried running:
1. Adafruit_NFCShield_I2C readMifare
2. Adafruit_PN532 readMifare
3. Adafruit_PN532 readMifareClassic
All of them resulted in the following error:
Didn't find PN53x board
(as a note, I did change the Adafruit_PN532 examples to work with the shield instead of the breakout on the lines).
I looked through the discussion board for others with the same problems and made sure to do the following:
- Check and recheck all the solder points
- Make sure the board was all the way into either of my audruino unos (I have two, and have tested both NFC shields on both Unos)
- Made sure to cut the IRQ connection with Digital 2
- Changed the usb cable
- Tried to push down on the shields when hitting the reset button on the audruino
As a note, the green power light is always on. The red light turns on as soon as I plug it in (for about 2 seconds), and then it turns off. As I understand it, the light is supposed to be on all the time.
The serial monitor is set to 115200 baud, and proper board and serial ports are always selected.
I'll attach pictures of both on this, and then of each board as a comment
