How to generate report?

Processing Electronics (Arduino, etc.)
1

Hi everyone,

I would like to know how to generate report using processing software based on values read from arduino.

The requirement for the report is to log every 5 minutes for 8 hours. and create new report file after finish the 8 hours.

The format must be in .csv.

is it possible?

Thank you
Jai kumaran

-a- make a table
https://processing.org/reference/Table.html
-b- add the values
https://processing.org/reference/Table_addRow_.html
-c- save to csv ( on timer or keyPress )
https://processing.org/reference/saveTable_.html

example:

// v01 get CSV line   // like: 1023,927,843,761,693,0,0   A0,1,2,3,4  D2,3
// v02 save to table

Table table;
String outfile = "data/arduino.csv";
/*
A0,A1,A2,A3,A4,D2,D3
1023,927,839,751,672,0,0

here is a timer



int timer; 
int i;

void setup() {
  size(555, 555);
  background(0);
  timer = millis();
}

void draw() {
  background(0);

  if (millis()-timer > 1000) {
    timer = millis();
    i++;
  }
  text(i, 33, 33);
}//

Hello kll,

Much appreciate your guide, will give a try asap

Thank you
best regards

I provide links to other discussions relevant to your topic. It is important to manage IO operations inside draw/serial functions specially if you have higher event rates scenarios.

I include “append data posts” as it might be useful in your use case.
