> Try this right after you receive string: println(inString); Try a delay() in setup() of Processing: I like to test code on receiving side with simulated data: String s = "113,206,46,212,102,195,211,114,33," + "\n"; print(s); s = s.trim(); // Trims that \n before processing string print(s); println(); println(s); String [] splitData = split(s, ','); printArray(splitData); printArray(float (splitData)); println(float(splitData[0])); float [] splitFloats = float(split(s, ',')); print…

> Hello. This can be considered an extension of my previous thread here [Using two different readStringUntil "characters"](https://discourse.processing.org/t/using-two-different-readstringuntil-characters/10769) Now, I am working on a basic Arduino project, but for understand Processing, I am now using a potentiometer to extend a line across the screen. I wish to extend it to 2D because it has been 1D Through Serial, I receive the values of the pot via Arduino. I know that separating a string using splitTokens() will give a pre-initialized array at some index that string. However he…

> Well, I was lost after the first 3 replies, however I think I can use an array and index the place of it Like maybe: float val[2]; int index = 0; //given that we are already reading from serial port called "port"... ... void func(){ //not sure which real function to put in the real code input = port.readStringUntil('\n'); val[index] = input; index = index + 1; input = port.readStringUntil('\n'); val[index] = input; index = index + 1; if (index \> 1){ index = 0; } pxval …
