How to upload data to a server with Arduino · GitHub
Sep 29, · I'd like to make that file available for download by the user through a simple button in the website. Any advice on how to set up this web server? PS.: I'm aware of the "SDWebServer" example, but I don't have enough pins available to connect an SD card. Send sensor data from arduino nano to firebase using esp01 - By rudy. Is it possible to. May 15, · How to upload data to a server with Arduino. GitHub Gist: instantly share code, notes, and snippets. Jan 07, · Installing Arduino Library from GitHub by James Lewis. It may be tempting to just download blogger.com and.h files then figure out where to put them. There’s a couple of other files that are included in an Arduino library, so this isn’t really the best option. Instead, on the project page look for the “Download ZIP” button.

Arduino Stack Exchange is a question and answer site for developers of open-source hardware and software that is compatible with Arduino. It only takes a minute to sign up. I made a sketch, but then I lost it. However, I uploaded it to the Arduino before losing it.
Is there any way I can get it back? It should be possible as long as the security bit isn't set. This question was asked on EE a while back. Is it possible to extract code from an arduino board? But you won't get the Arduino code you wrote back. The code is compiled into assembly and you'll have to convert that back to C yourself. The Arduino IDE uses temporary directories to store build files, including the original sketch download file from ardunio server well as the HEX and intermediate files.
I've found that especially in Windows, these build files don't get deleted when you close the sketch or IDE, so they may exist on your machine for far longer than you would think. Also, by default, Crashplan, Backblaze and Time Machine back-up these locations, so even if they have been deleted, they may still be in a backup.
If you can understand assembly, you could download file from ardunio server the program, but that would take a while. There are dissasemblers available for some devices, i don't know about arduino. I think there is another way to do this, without extracting the code from the Arduino board. You could find your unsaved code unless it was deleted by some "freeing space program". Good luck! Unless your objective is to simply copy the identical code to another device, the simple answer is: no.
As has been pointed out in other answers, download file from ardunio server, you can turn the hex code on the device back into assembler code. As you can see, not particularly helpful for reproducing what your sketch did.
There are likely to be one of two scenarios:. In the "short sketch" case, you are better off just rewriting from scratch. That would be faster, almost certainly. In the "long sketch" case - it just isn't worth it, download file from ardunio server. None of the variable names are preserved, and the download file from ardunio server the compiler optimizes download file from ardunio server, even the structure of the code would be hard to determine.

This answer doesn't directly answer the question, but still will result in the same end result, download file from ardunio server. The advantage here is that you will recover C code rather than ASM.

This is the best solution IMHO. Very creative, too Comment echo from the accepted answer: Reading back the raw hex: forum.

There are multiple ATmega disassemblers google atmega disassembler. If you have the arduino envitonment, you already have avr-objdump as it comes with avr-gcc.

Unless your objective is to simply copy the identical code to another device, the simple answer is: no As has been pointed out in other answers, you can turn the hex code on the device back into assembler code. For example once you have copied the code from the device back onto your disk : avr-objdump -j. There are likely to be one of two scenarios: Your sketch was short, in which case you might, after weeks of work, turn the assembler code back into C Your sketch was long, in which case it would be virtually impossible to turn it back into C In the "short sketch" case, you are better off just rewriting from scratch.

Dec 01, · Just a thought. If I have Arduino server loaded with web pages, why not having a few links on the web pages that point to several data log files for download? My question is, how to? I have some rough ideas so I appreciate it if experts can help me polish the ideas before I go ahead and code it (into non-working result of course). May 28, · Basic Arduino web server compatible with most Arduino boards and Ethernet shields, works with the Uno, MEGA and other Arduinos. The web server uses an SD card to host the web pages and other files such as CSS, images and JavaScript. I use an Arduino Uno and an Ethernet shield with WIZnet W My text file is called blogger.com With different information found on internet, I wrote the following code, but when I put the IP address in my web browser, I have an automatic download of a file called "blogger.com" but it is totally empty! I don't understand why I have no data in my file.
