Hi all, I have a need for a serial monitor with a binary dump feature, not a technological poo, but a 'save raw data to file' feature. The only decent app I found so far is 'advanced serial port monitor' but its not free and my trial expired.

All I need is to save a TFT screenshot to the computer ( bitmap header is sent in data ). Or maybe someone knows of an app that can receive image data via serial?

Cheers chris.

I often use putty.exe for this

I gave putty a try, but I cannot see how to save the output as raw binary, the saved log file is larger than the amount of data sent. Any hints.

try under logging -> all session output

Code:

void setup()
{
  Serial.begin(9600);
  for (int i=0; i<255;i++)
  {
    Serial.write(i);
  }
}

void loop(){}

viewing with a hexviewer gives output as expected

HTERM rocks! it is free and very powerful

You are right!

It was exactly what I needed, I tried maybe 8 different serial apps... All pretty much useless, well not useful for my needs.
HTerm was so straight forward, option for raw save and 2 clicks for capture. Finally got some screen captures happening.

Thank you.
Thanks robtillaart too, your input is appreciated.

 Any recommendation where to download the app. from? Preferably an English site. I found a few places using a search but, I was worried about getting added crap with it.

What about Terminal v1.9b also free

I especially like the macro buttons & although I've not tried has inbuilt graphing capability

https://sites.google.com/site/terminalbpp/ should get you there...

 Thank you! I looked the program over and I like it! I will have to test it later and try out the features.

That is the so called brey terminal and is a wonderful troubleshooting tool, I''ve been using it for years. I see I'm a rev behind and will have to check out the latest version.

Here http://hobby-roboter.de/forum/viewtopic.php?f=4&t=139 I've written a python program for displaying and logging data from the arduino.

To write data to a file from Arduino is quite simple:

Code:

 Serial.print("w2file "); Serial.println(sensorValue); // write value to file

A demo program for logging analog values would be as follows:

Code:

int sensorValue = 0;        // value read from the pot

void setup() {
  // initialize serial communications at 9600 bps:
  Serial.begin(9600);
}

void loop() {

  //Serial.println("cls"); // clear screen
  Serial.println("pos 0 460");  // set cursor position to 0,460
  Serial.println("print write analog values to file");
  
  Serial.println("pos 100 300");  // set cursor position to 0,460
  sensorValue = analogRead(A0);                      
  Serial.print("print "); Serial.println(sensorValue);  // print value on screen
  Serial.print("w2file "); Serial.println(sensorValue); // write value to file
  delay(2000);
        
}

It (still) has a nasty buffer corruption bug.  For most uses the bug falls somewhere between irrelevant and minor inconvenience.  For logging binary data the bug is a show-stopper.

Even with the bug, it's the terminal application I turn to first.  Lately I've been using Python for "advanced" applications (like logging binary data).

Coolterm can record the serial info and save it.

HTERM kicks all other serial monitor virtual asses  I ve tested them all
