I'm using arduino with processing. I'm sending a 10 character string from arduino to processing, using Serial.prinln(); I receive the same string in processing without any problem. But when I compare the same string inside the Serial Event function in processing, it doesn't match. I don't understand the reason. I tried different reading methods. nothing work. Then i read the serial port using a byte character array and converted it to string and then compared it. doesn't work. I need to used these serial read strings to load a picture to the window and display. Please help.
