Hi, I had a problem with my Processing data collection: essentially when my data comes in from the Arduino and to Processing, I save it onto a csv file. However, on the csv file it so happens that a value for one time stamp, such as 16 seconds and 5 milliseconds, get printed many many times onto th…

Hi @saaqib.m We really need to see the code, for Processing and Arduino, each in a code block. As well as that, try this. Use the Arduino IDE’s Serial Monitor to look at what’s coming from the Arduino. That is just as often as you expect it? e.g. one every second? So you know the problem is n…

Hi Richard, Thank you for your response, here are some snippets of the code, all of which are relevent: Arduino: #include <SoftwareSerial.h> int analog_output; //Serial Read output int sample_output; int r_pin = A0; //Initialising output pin u…

Hi again @saaqib.m , I’ve run your code in Arduino and Processing. In the draw() of your Ard code there are two blocks of code sending the same value, total of 3 times. I guess you were trying different things. In my version I’ve just used one. I’ve used the loop delay so that it sends twice per …

[image] Using two different readStringUntil "characters" Electronics (Arduino, etc.) The solution I gave on that link expects the Arduino C code to send the multi-data as if they were a row of tab-separated values (TSV): face_with_monocle That is, each value is follow…

Hi Richard, Thank you very much for your response and your code is very nice to work with! Allow me to elaborate further. The 2 blocks being printed is my kind of ‘sampling’, it isn’t the most effective right not but that is not the focus. For now every time the time reaches the DELAY_TIME it shoul…

Thank you! I shall have a look.

Don’t apologise for your serial event not working. I don’t know why, assumed it worked on your PC but not on mine. I was cutting it down to see how it differed from the example, but gave up.

try this example see how receiving an sending then mange your code // This example code is in the public domain. import processing.serial.*; int bgcolor; // Background color int fgcolor; // Fill color Serial myPort; // The serial port int[] serialInArray = new int[3]; // Where we'll put wh…

try to use 2 arrays you are using just one void serialEvent (Serial myPort) { // get the ASCII string: inString = myPort.readStringUntil('\n'); //println(inString); String [] splitstr = splitTokens(inString); if (splitstr[0] != null) { //inString = trim(inString); …
