Java and pi4j implementation for the pn532 nfc module with a Raspberry Pi

raspi-pn532's Issues

Hello, can you update this item to pi4j 1.1, meanwhile, there is a bit less annotation for the novice.

pn532i2c.writeCommand exception occured

Hi,
first of all thanks for sharing this library.

When I run your program, using i2c connection, everything runs ok.

But after a few moments I get the error:

pn532i2c.writeCommand exception occured: Error writing to /dev/i2c-1 at address 0x24 to address 0x24. Got -20001.

Do you know what could be causing this?

Forked and updated (for I2C/UART, SPI untested)

Modified for personal use, figured I might as well upload the changes: https://github.com/ScottyDoesKnow/raspi-pn532

Just putting this here because it seems this repo is dead.

Exception: Cannot open file handle for /dev/i2c-1 got -1 back.

hey so i'm testing you're code with out the pn532 board Connect and im getting the following error when running the program

pi@raspberrypi ~/NetBeansProjects/NFC/dist $ sudo java -jar NFC.jar
Starting up...
Exception: Cannot open file handle for /dev/i2c-1 got -1 back.
Exception in thread "main" java.lang.NullPointerException

at nfc.PN532.getFirmwareVersion(PN532.java:28)
at nfc.Main.main(Main.java:16)

is this becouse i don't have the board connected ore is there somthing wrong with my setup ?

No license specified

Hi there,
It would be great to add a license to the project.
I would like to use your code for commercial purposes but without any license I'm not sure about the right to do it.

Thanks

can't get it working with spi

hey so im traying youre code out and i can't get it working with this board

and the following wirring im running a raspberry pi 2 mobel b

MISO pin 21 to MISO
SCLK pin 23 to SCLK
pin 24 to ss
GPIO 0 pin 11 to RSTO

gnd pin 6 to gnd

the output from the program is when set in debug mode

Forked and Updated (raspi-pn532-v2)

I forked this a while back and got it working for personal use, but I've finally put the time in to basically re-write everything and make sure it all actually works this time. You can find it here: https://github.com/ScottyDoesKnow/raspi-pn532-v2

Would you please update this project with pi4j 1.1.And add more commit of code.
