Port sharing

I have my Processing InvertedSonar sketch working successfully – I.E it is showing the concentric circles.

However, when I run my Arduino on port tty/ACM0, processing no longer has access to that port and I get an ArrayIndexOutOfBoundsException

Can you think of anything I am not doing or doing wrong to get both sides communicating?

ps: Apologies if I am not being descriptive enough. The fact is I am not very sure about anything processing and/or Arduino related

When Processing starts the InvertedSonar sketch it prints a list of all serial ports to the console. Can you post this output, please?

Hi Maik,

Thank you for your response.
I have made some progress since my original posting.

I am getting the following output:

Stable Library
=======================
Native lib Version = RXTX-2.1-7
Java lib Version = RXTX-2.1-7
RXTX Warning: Removing stale lock file. /var/lock/LCK..ttyACM0 [0] ”/dev/ttyACM0”
Temperature: 0.0
Distance: 0.0

As you can see can I am getting some output but my Adruino code is outputing the following:

40.71, -24.611

I am working on things but I would appreciate any suggestions.

ps: I should mention I could not procure a Ping))) sensor and I am using an HC-SR04 sensor instead.
This means the code in the text was imcompatible and I had to find alternative code. So, whilst your code prints long value types, my prints floats for the temperature and distance values.

Hey Maik,

I got it working.

Thanks!
