I need to send a couple of parameters from Processing to Arduino. I caneasily send one number, however, when it comes to a string, say “45_22_65” I suddenly start getting problems.
The problem is that I can’t see what is that Arduino receives (I can’t open the serial port monitor as it is used by Processing) and the line is not decided accurately on the Arduino side (Inlook for the “_” to cut the line into separate chunks).
I thought that ‘underscore’ might be a bad separator or it is transmitted in a different way. Is there anything else I have overlooked?
