How To Transfer File Using Putty Serial Monitor

One time only: If the X login screen is running and you just want to connect to it once (i.e. A one-shot): It is usually possible to do this by just adjusting the.

Since you are writing your logs on the SD card you should already know how to write (and read) from it. My understanding is that you have a USB connection.

So, in principle, you may transfer the file by repeatedly reading the file and calling serial.write(). The process would be started by the PC sending some message to the Arduino over the serial port. A basic 'protocol' could be: - send a command (e.g., GET) from the PC to start the transmission (no need to specify a file name, the PC will save the data under a local file name of your choice); - answer by sending your data divided in small binary chunks (same length, may even contain a checksum); - for each chunk of data sent, wait for the PC to send an ACK (and define what to do if no ACK is received within a certain amount of time); - send an EOF when you have sent the last chunk of data. This would be pure serial transmission so you shouldn't interpolate the usual debugging messages. I'm a bit confused, maybe missing something. I understand that you have been able to configure two COM ports on your PC, both can listen for messages from the Arduino and (maybe) send messages to it. Is it a Mega?

Anyway, if you already receive data on putty. Well, I don't have putty (on Mac) but I believe you can configure it to append new data to an existing file. You'll need to have putty running forever, but this solution is undoubtedly faster than implementing a file transmission protocol, however small. Coreldraw X8 Keygen Download. As for sending data to com1 instead of com5, the answer is in your code. If you decide to write a function to send data on different ports you'll have to post the relevant parts of your existing code -- one cannot guess what is currently sent to com1 vs com5 and where and how the code needs to be changed. Didn't mean to be confusing.

I didn't necessarily configure 2 com ports. I have Putty installed from another project having nothing to do with this Arduino project and I just noticed it was on com 1. Com 5 is the port that the PC set the Arduino to, nothing I did.

At War With Self Torn Between Dimensions Rarity. I don't know how to direct the serial.write to com1. The com 5 I am refering to is the com port the Arduino is connected to and as such, the Arduino serial monitor. As for Putty running forever that is not a problem since it's a dedictaed PC just for this project and as long as I need to collect the data. Right now I'm only using some test code to get this thing working. When I write to the SD card I also wrote to the Arduino serial monitor to verify the data that's passing through.

How do you modify the code to write to Putty through com1 rather than the Arduino serial monitor through com 5? I hope that clarifies things. I really appreciate the help. Yes, now I understand. But no, the Arduino cannot communicate with the PC using a different com port than the one assigned by Windows, com5 in your case. You can, however, open a new putty session and configure it to listen on com5 instead of com1.

Just don't do it when the Arduino serial monitor is open because there would be a conflict (and close putty before using the Arduino IDE to upload a new sketch). Once you have configured putty (look especially at the baud rate, it must match the one used by the sketch) it will work as the serial monitor, allowing you to save the log to a file. Then, in your sketch, you'll need to comment out (i.e., prefix with //) all the debugging statements you print to Serial, and add the Serial.print() instructions for the data you want to log. This is not an optimal solution, it's tedious to implement and leaves you without the information that the debugging statements can provide. On the other hand it's relatively quick and less likely to introduce bugs that would require time to be fixed, disrupting your data collection.

Anyway, make a copy of your original sketch so you can quickly revert to a working condition.

This article is part of on-going series. PuTTY is hands-down the best, free, and lightweight SSH client for Windows. I have provided list of 12 powerful PuTTY add-ons with screenshots, that will solve few shortcomings of the. Play around with these add-ons and choose the one that suites your need. Gives a nice feature to arrange several PuTTY sessions in tabs. While starting PuTTYCM for the first time, you should specify the location of the original PuTTY. This requires.NET 2.0 to be installed on the windows system.
