how to save serial monitor in the text file?

[NateDuong]

 Dear everyone,

I trying to  save serial monitor in the text file, but I still do not know how, could you please help on this problem?

Here is the codes with random numbers are set up, and I would like you save all data into the text file,

Thank you very much,

Best regards,

Nate Duong,


long Channel1a;long Channel1b;
long Channel2a;long Channel2b;
long Channel3a;long Channel3b;

long Channel4a;long Channel4b;

int count1 = 0;
int count2 = 0;
int n1 = 1000        +1;  //  +1 is missing count
int n2 = 2         +1;

void setup(){
  Serial.begin(9600);
  randomSeed(analogRead(0));
}

void loop(){


while(count2<=n2){
  //Serial.print("nate1\n");
   while(count1<=n1){
     if ((count1==2)|(count1==1)){
               Serial.print("     Q1     I1     Q2     I2     Q3     I3     Q4     I4 \n");  // print out the channels
                   }
     Channel1a = random(300); Channel1b = random(300);
     Channel2a = random(300); Channel2b = random(300);
     Channel3a = random(300); Channel3b = random(300);
     Channel4a = random(300); Channel4b = random(300);
   
     Serial.print("    "); Serial.print(Channel1a); Serial.print("    ");
     Serial.print(Channel1b); Serial.print("    ");
     Serial.print(Channel2a); Serial.print("    ");
     Serial.print(Channel2b); Serial.print("    ");
     Serial.print(Channel3a); Serial.print("    ");
     Serial.print(Channel3b); Serial.print("    ");
     Serial.print(Channel4a); Serial.print("    ");
     Serial.print(Channel4b); Serial.print("    \n");
     count1 = count1 +1;
     delay(500);
                      }
                 }
     count2 = count2  +1;
     Serial.print(" \n");}

I use putty as my serial terminal on the pc and there is an option to log all the data in a text file.

The Arduino Serial Monitor, like the reset of the Arduino IDE, is quite primitive.  If your data is too big to Copy and Paste (into a text editor) all at once, then there is no way to use it to do what you want.  Fortunately, there is nothing special or proprietary about the Arduino Serial Monitor, and you can simply use another "Terminal Emulator" or Serial Communication Tool.

I also use putty on windows, and I use minicom on MacOS and Linux.

RealTerm and TeraTerm are very good doing that, however, you can easily program your own application for that, search "boost serial port" on google and you will founs a bunch of working examples.

Yes. It's too easy to write yourself. It just takes a few days of your life.
Use mine:
https://github.com/Jeroen6/MultiTerminal
^{(it does not actually dump it into a file continuously, plenty of logger tools around for that. It can however split your channels realtime)}

On Linux I use the SCREEN program. It allows you to connect to serial devices, create multiple sessions, and take screenshots or run continuous logging.

I use it to collect muon detector data for days or weeks at a time. Gigs of data. Works great.

On a Unix machine or a Mac OsX, it can be done in a single line  of shell

nohup cat /dev/cu.usbmodem1d11 > temp.log &


replace  "/dev/cu.usbmodem1d11" by the port you are sending data to
and "temp.log" by the name  the file you want to store data in.

If you need to capture all the serial events on a txt file with an Arduino without the PC you can do it on a SD card.

Take a look here


Or you can search for Arduino datalogger, it is pretty straight forward.

Meh. Probably I'm getting old, but I would do it with a batch file. Or just type it to cmd.exe

mode COM1 BAUD=115200 PARITY=n DATA=8 TYPE COM1 data.txt

[NateDuong]

Dear all,

Thank you so much for your recommendations,

But the best way I tried with Batch file,

It really worked.

Thanks again.

Best regards,

Nate Duong.

For generic text capturing, Teraterm works rather nicely.

If data parsing or other feature is needed, a quick Java program is a good choice too since the Arduino IDE environment already have all the Java classes needed to talk to the Arduino.

mode COM1 BAUD=115200 PARITY=n DATA=8 TYPE COM1 data.txt

That might come in handy some day.
