Processing RS-232 data corruption.

in Core Library Questions • 7 months ago

I'm attempting to log tempature over time using an Arduino and Processing. The Arduino communitates with Processing using RS-232 however I am getting corrupted data when I attempt to read the Arduino with my processing sketch. I've tested this with Putty(serialterminal) and the Arduino serial monitor, both seem to display the data correctly so I'm certian the issue is with my processing code.

Processing code:

Processing sketch output:

What it should look like:

Note: you should avoid pasting images for textual information. It makes the thread heavier (not so important these days, but still) and more importantly, the information cannot be searched nor copy & pasted.

I am not a serial specialist (never used it) but myPort.read() reads a byte, not a char. These are different in Java. char is a 16-bit unsigned, Unicode value. Perhaps try readChar().
