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
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.
Author's page: HTerm - der-hammer
What about Terminal v1.9b also free
I especially like the macro buttons & although I've not tried has inbuilt graphing capability
Terminal 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 hobby-roboter.de 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:
Serial.print("w2file "); Serial.println(sensorValue); // write value to file
A demo program for logging analog values would be as follows:
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
@Eried,
what is THE feature HTERM has that other terminals are lacking? or what is the shoe that kicks the A.

Hahaha with some German/Dutch wooden shoe I guess. Well I am not sure about the feature, it is just rock solid in everything, UI, features, no-bugs. I haven't checked recent monitors however.
with some German/Dutch wooden shoe
that really hurts I know
Rock solid sounds good, I downloaded HTERM to my desktop and give it a try
HTerm seems to lack macro buttons as available in Bray Terminal (Terminal 1.9b). I'm sure someone will correct me if I'm wrong....
