Trouble with I2C

Hi,

I try to get a stripped-down version of the example for I2C from the PI4J site (https://pi4j.com/documentation/io-examples/i2c/) running.

The main method starts with the following statements:

		Context pi4j = Pi4J.newAutoContext();
		I2CProvider i2CProvider = pi4j.provider("linuxfs-i2c");

Unfortunately I get teh following exception when trying to get the I2CProvider:

Exception in thread "main" com.pi4j.provider.exception.ProviderNotFoundException: Pi4J provider [linuxfs-i2c] could not be found.  Please include this 'provider' JAR in the classpath.
        at com.pi4j@2.0-SNAPSHOT/com.pi4j.provider.impl.DefaultRuntimeProviders.get(DefaultRuntimeProviders.java:238)
        at com.pi4j@2.0-SNAPSHOT/com.pi4j.provider.impl.DefaultProviders.get(DefaultProviders.java:147)
        at com.pi4j@2.0-SNAPSHOT/com.pi4j.context.Context.provider(Context.java:240)
        at de.rziegaus.ATECC608A@1.00/de.rziegaus.SimpleATECC608A.main(SimpleATECC608A.java:18)

So I added the dependency for linuxfs-i2c, but now I get a different problem with the program. Now I get an exception saying

Error occurred during initialization of boot layer
java.lang.LayerInstantiationException: Package lib.armhf in both module com.pi4j.library.pigpio and module com.pi4j.library.linuxfs

If I remove the jar files concerning pigpio (library and plugin) manually everything works fine - at least I don’t get any errors when I run the stripped-down version of the program.

What concerns me a bit - do I really have to choose between either pigpio and linuxfs-i2c? Or is there a workaround?

Ok, the problem is resolved. I have downloaded the latest snapshot and now it works.

Thanks for your help,

Ahh, good to know! I was hoping to find some time this weekend to test it out again. But now not necessarily.
