nkolban / jpigpio Goto Github PK

Notes:

1.) Compile java code to .class files:

• unzip master.zip

• cd jpigpio-master

• cd jpigpio

• mkdir bin

• javac $(find . -name "*.java") -d bin

2.) Change JPigpio/Makefile install dir: i.e. /home/pi
3.) Change JPigpioC/Makefile to match above: i.e. /home/pi
4.) Make sure JAVA_HOME is set (mine wasn't). Added it to makefile.
5.) Run make from jpigpio-master

Hi,

Sorry if I've missed something but I'm not sure how to get the required jar.

I tried make but it seems to need a file in /mnt/share/opt/lib/Pigpio.jar

Thanks

Sam

Hi there.
I'm trying to use your PIgpio, more exactly the MFRC522 interface but I can really understand how can you continuous looking for when a card is close to the RC522 module.

Do you have any example that can share with us?

Kind regards

Hi,

Is there a technical reason for not providing a socket version of gpioSetAlertFunc?
pigpio itself seems to provide it.

Thanks

Jim

Is there a class that wraps around pigpio's PWM support?

Hi,
I'm trying to use this library as a good alternative to WiringPi as it does not require root permissions (at least not for socket access), but I'm missing implementation of serial functions (I'd like to connect serial printer :-).
Would you be so kind and add those?

Thank you.

Jozef.

Getting error "Can't lock /var/run/pigpio.pid" when attempting to run Blink_Test as shown below:

Hi!,

Can you upload the library to Bintray to use it with Gradle?

Best regards,

I finally got JPigpio properly installed and running with pigpio but when I run the Test_Blink or the Test_gpioSetAlertFunc I get no response out or in. I can run another program using pi4j and these same pins respond. Any ideas? I get no error messages and jpgpio test code runs as expected just no I/O.

Do you have a example for Java?

I want to use the MFRC522.java but I couldn't find unit tests or sample files that show how to use it. Any pointers are welcome.

Hi! For easier development i am trying to release the Build to Maven repository.

I will also update the Documentation about Build & Install some time in the future.

Ticket for requesting a repo at sonatype: https://issues.sonatype.org/browse/OSSRH-28498

I added @nkolban and @sovcik to the developers in metadata of the parent pom.xml.

If i can do something else, please tell me!
Thank you very much for developing this project so far!

Hi there.
