Add the following lines to your .bashrc file so then you should be able to call the command processing-java
from the command line.
# path to the processing-java binary
export PATH=$PATH:/YOUR/PATH/TO/processing-3.0.1
This board simulator is written in python 2.7 and involves serial communication, spawning of a sub-process, scheduling of a recurring operation.
The serial port creation/mapping is done with socat e.g.:
$ socat -d -d pty,raw,echo=0,link=/tmp/ttyRX pty,raw,echo=0,link=/tmp/ttyTX
Where /tmp/ttTX is the virtual serial port where the simulator writes data regarding the Arduino UNO board and /tmp/ttRX is the port where the Processing dashboard is reading the data.
Run the simulator from the command line like:
$ ./boardValuesSimulator.py
To check what is being written on the serial port use screen like:
$ screen /tmp/ttyRX 9600
When the Processing dashboard does not find any real board printing data on a USB serial port, then it assumes
there's a simulator running and printing data on /tmp/ttyRX.
Run the bash script buil-processing.sh. It should generate the java code and bytecode inside the folder bytecode-out
and run the java process for that bytecode.
In the picture below you can see:
- a summary of all the (parsed) sensor measurements (accelerometer, gyroscope, magnetometer, temperature);
- a compass pointing to the magnetic north;
- a series of dots representing a (really really) basic temperature graph :)
I should be organising this dashboard with more details, but for now this is it.
The compass has been copied from the great work done by jarzebski on his repository.
