Jarduino witht Arduino Mega

[frickerm]

Hey there I want to use Jarduino with an Arduino Mega because i need more digital output pin

but if i enter PIN_33 Output for example there is an error because they dont know the variable PIN_33

Can i extends the source code and how can i do this

[brice-morin]

Hi,

Yes, you can extend JArduino to support Arduino Mega. Some files you should extend:

• https://github.com/SINTEF-9012/JArduino/blob/master/jarduino.core/src/main/java/org/sintef/jarduino/AnalogPin.java
• https://github.com/SINTEF-9012/JArduino/blob/master/jarduino.core/src/main/java/org/sintef/jarduino/DigitalPin.java
• https://github.com/SINTEF-9012/JArduino/blob/master/jarduino.core/src/main/java/org/sintef/jarduino/PWMPin.java
• (Maybe) https://github.com/SINTEF-9012/JArduino/blob/master/jarduino.core/src/main/java/org/sintef/jarduino/InterruptPin.java

You might need to extend the JArduino firmware as well, adding pins:

• https://github.com/SINTEF-9012/JArduino/blob/master/jarduino.core/src/main/arduino/JArduino/JArduino.h

Maybe more files, but you can start with that and it should pretty much be ok

Ok thank you I found and change the JArduino.h file but i don´t can find the DigialPin.java where was there saved

[brice-morin]

Not sure I understood... but if you are looking for the DigitalPin.java file, you can just click the link https://github.com/SINTEF-9012/JArduino/blob/master/jarduino.core/src/main/java/org/sintef/jarduino/DigitalPin.java

Okay I downloaded the JArduino 0.1.7b because i has Updatet my Arduino Software then i copy the firmware in the sample folder of the Arduino softwar now i load the other files of the dowload in my java Ide (eclipse)

the import DigitalPin works but i dont know where does the import saved and where can i change

[frickerm]

I found them on lib but there are all class files how can i change them now

[brice-morin]

Maybe the easiest is to start from the source, by cloning this repo.

[frickerm]

okay now i changed the class file

to this

}

but eclipse dont fint PIN_40 for example

[frickerm]

or can you send me the chanced import jar files via email

[email protected]

[brice-morin]

You can regenerate the jars with Maven. man clean install

[frickerm]

Ok i dont know what i should change

did someone else changed this and could send me please

[frickerm]

when i copy the changed DigitalPin class file in the jar file (imports)

should i certify the class file

because if i open the class files with an editor there are all encoded and the changed is readable

[brice-morin]

I would not recommend changing the content of .jar files by copy/pasting modified .class files.

• install Maven
• modify the sources as you did
• run mvn clean install at the root

[frickerm]

sorry but it dosent work

[ScottBruton]

Guys, I really want to extend jArduino to work with Arduino Mega. I tried understanding the above threads but I'm still unsure what to do to do this.

Please can someone tell me step by step how to change jArduino files to be able to include all Analog Pins ( A0 - A15) and Digital pins (D22-D53).

Thats all I need.

Thank you Scott
