How to Read and Extract HEX File from Arduino Board And Upload the HEX File to Another Arduino

[@Ciiads]

IMPORTANT NOTICE: After watching this video so many of you asked. how to do this with uno as the programmer and the mega as the target , mega as the programmer and the mega as the target. and many of you guys requested the wiring diagram for that again and again and i helped many of you around the world through email. You know, answering tons of emails is so hard but that's not the case there is a probability to miss some of them. I don’t want that to happen like that. So I updated the video description. You can download those digram's from there. Even if in any case I miss your mail. Have a great day. Thank you . Regars. Aneeshmurali.N

You did great job. Can you help me to get hex file from STM32F030K6T6 microcontroller and write it to new one.

[@MR.NiLanka]

I tried this method and it detected MCU as ATmega328p and Fuses & lock bits still remains same as 0x00 but it says SUCCESS: Read high fuse SUCCESS: Read low fuse SUCCESS: Read extended fuse also SUCCESS: Read lock bits I'm waiting for your advise. Thank you. 😊

[@gehirnenterprises]

This was so helpful. I can verify it works with Ardunio Leonardo, but the ICSP header must be used as the pins are different. It also works with Arduino Micro. Much easier than using Microchip studio in professional mode. Thank you Aneeshmurali !!!

[@theDaftman]

to do what you have in this video is very simple one just need a rs232 port and PonyProg (free downloadable software) on your computer and a simple diy adapter that plugs onto the Arduino's icsp , one can then copy any code (hex file) from a Arduino in seconds. one can also load a hex the same way. even read/write the fuse setting.

Hi, this does not seem to work for me. I hooked everything up and AVRDUDE says its reading the flash and writes a file. But no matter what program I load on the target the hex is always the same file. Even if I disconnect the target board and do the read operation it completes successfully and just writes the same file. How is this possible? What am I missing.

[@Ciiads]

Do selection manually. Make sure the port selection was right. Keep the programmer type to usbasp. Then upload if everything is normal it will work without any issues. If you getting any issues again try to reinstall Arduino ide. The clone version of arduino's are made with usb to TTL chip it doesn't has any firmware on it. So if you connect this kind of board to the computer it will show only the port number of the connected serial chip. Sometimes with the name of the serial chip like ch340g Ftdi etc. But the original version of arduino's has a dedicated microcontroller with firmware on it. which is doing the same job as the serial chip. and the name of the usb device is embedded on it . That's why we can see the name Arduino Uno , etc like that.👍 If you are interested swap a usb to TTL serial chip with atmega 328p having bootloader then you can make your own Arduino at home just by yourself.😊🤞👍

Does the method explained in you other video "How to Stop Cloning Your Arduino Atmega328p Programs, Do This" prevents the ".HEX "file to be read by the method explained here ??? If not, then the protection agains cloning would not be efficient... Thank you for your reply,

[@Ciiads]

Normally Arduino doesn't have any protection so you can read the hex file back like this but if you want to prevent that then that's the way to do it, it will bit lock the chip.

[@elodiecemoi3057]

@@Ciiads OK, so if we set the "Lock bits" and "Fuse bits" as described in your video "How to Stop Cloning Your Arduino Atmega328P Programs, Do This", it should be impossible to read the ".hex" file, even with the method explained in the video on this page. So you have answered to 2 different problems: how to stop reading .hex file (if we want to prevent reading) and how to read .hex file if the programmer has not specifically used the lock bits.

i flashed my arduino uno board using flip and now i cant find it in the device manager or ine the ide software(COM number) i want to reprogram the board what should i do thanks

[@Ciiads]

In the device manager you can definitely see the com port of the connected device. If it's not showing the connected device. Then that might be a cabling issue or the connected device may be faulty or may be your arduino board is based on some serial chips like FTDI or ch340g etc. If they are based on serial chip like this. then , on the device manager show's the name of the serial chip with appropriate port number not the name "arduino uno". literally arduino clown's are based on serial chip's. May be the flip erased firmware of your primary microcontroller (mega16u2) on the arduino board which is acting as a usb to serial converter for the main chip atmega328p. With out that it will not communicate to the pc and back to back. So Reflash that chip if the firmware is available. or replace that mega16u2 MCU with a serial chip like FTDI or ch340g etc that will do the job fine. For about Reflashing firmware of mega16u2 check this blog that may be helpful for you www.instructables.com/How-to-Restore-the-Arduino-UNO-R3-ATmega16U2-Firmw/ Thank you 😊.

Hate TFT's listed as X but not X,Y or even Z :/

[@Ciiads]

Arduino mega have some pinout difference. That's the problem. So the wiring diagram is also different.more over that we need a different Arduino isp sketch for Arduino mega's. You just DO NOT erase the Arduino mega having your valuable program. We can take that back from it. Don't worry about it. but you never get your library and source code back. The compiled executable file (.HEX) is the only thing we can get back from it. Although if you got that file it is impossible to get the source code, but you can make many copies of your project. Do you have any Arduino uno board ? Then we can make a try without changing the Arduino isp sketch. and i will forward you the wiring diagram.❤️🤝😊

[@Ciiads]

I agree with this. That's true. Arduino Uno was not for industry but there is nothing wrong with atmega 328p. Nobody use development board for commercial purposes right. But you can use the chip 328p for commercial designs but use proper toolchain for the embedded system development. Like atmel studio it is the official ide for avr mcu development. it's not easy as you did in arduino ide. you need to write you'r own library and code for your project. and the project is yours you can market that. arduino ide and the library's that came for arduino and the hardware it self is opensource. Because of this reason it's not well optimised and not Bugg free more over it's opensource too.

[@Ciiads]

did you know the meaning of protection. I'm just kidding . No brother no way. if you do anything with the locked chip or if you try to change the config word it will erase the chip. but there are techniques of reading protected chip which require high end equipment like electron microscope, etc which is way beyond the reach of enthusiasts. and that is illegal. The methode is like decapping the chip and read it out with an electron microscope, or selectively resetting the security bits with UV light by somehow masking out the rest of the die but I'm not sure about the success rate and nobody will attempt to do that because it is impossible to do. if i were you i will write a new firmware my self. which is far more easier and better than attempting to copy a protected chip and wasting valuable time. if you are curious in embedded electronics then work on your skills. I wish one day you can write your own firmware your self. the learning curve is about miles long but the time you drive on the road will worth it. Regards, Aneeshmurali.N.

Hope You can Understand and help me;

[@Ciiads]

If you truly believe it is pic 12f675 and the chip is not locked then you can copy the program using a programmer called pic kit. but the program is not portable to other mcu's. because of the architecture and the instruction set, registers, memory mapping,io peripherals, address, are different in mcu's to mcu's. But it is possible to the same chip. its not like the way we are installing apps on our phone pc etc that will work phone to phone or pc to pc because of the instruction set's are the same. and it is not possible to create the same effect on Arduino by the copied program. But it is possible to write a new program like the way you want to create the same effect. and the last thing you mentioned probably have a chance to success. If you accurately copy the timing of data signal. then you can regenerate that using Arduino or any microcontroller but it is hard to copy the fast square wave like that. a percent of error will affect the system badly.

Wow another amazing question ,fuse bit's are not the villen here. mcu code protection is based on lock bit. Okay came back to the question , if you want to check the chip is locked or not you just read the lock bit value. Then you can identify its locked or not and one more thing in case if the chip is locked then you think you are going to change the lock bit and read the hex its not possible if you change lock bit it will erase the memmory. So you didn't get any thing. Ok in order to know which is the locked and unlocked lock bit value i prefer refer the chip datasheet or just look around avr fuse calculator its an online calculator for avr.

How can we convert hex file into arduino code? I want read hex files to understand the arduino code.. How can i do that...

[@Ciiads]

You can't. Even if you find any decompiler to do that still you can't convert that into the original source code but you will get the decompiled source code that works but not the same as human written original source code because it is computer generated right.👍

how do program micro PIC ??

[@Ciiads]

What you mean exactly Writing program or flashing firmware. However Mplab is the official ide to develop software for pic microcontrollers. And pickit is the programmer/debugger.

how to translate hex file into arduino program? thats the question

[@Ciiads]

Actually, the hex file is the program Anything you wrote on the Arduino ide or any ide is called source code Here, the source code is based on embedded c or c++ At the time of the compilation of the source code, the compiler translates that into the machine code like instruction by instructions according to the specified MCU Like we wrote the program in assembly (opcode and mnemonics) remember. So if you want to translate that hex file code back to the source code is possible by a decompiler program if it is available but it is a machine-generated source code it works but it will not be the same as the original source code. I mean the variable names constants and function names and everything is different in there because it's a machine generated source code. So it's very hard to edit and debug. and always if you are skill full guy You can transcribe the hex code back to opcode and mnemonics (assembly code) Manually by referring the instruction set and the architecture of the mcu but it's a time-consuming and a painful process If I were you I will write a new code for my application because that's very easy for me. Thank you for your question Regards Aneeshmurali.

@@Ciiads thanks, i hope someone make this convert tool very soon

[@Ciiads]

Anyway, decompiling a hex file will not give you the exact same source code that you originally wrote, as the decompilation process is not perfect and can introduce errors or inaccuracies. There are several reasons why the decompiled code may differ from the original source code. One reason is that the compiler optimizes the code during the compilation process, which can result in changes to the machine code. Additionally, some compilers include code obfuscation techniques, which can make the decompiled code more difficult to read or understand. Another reason could be that the libraries used in the project could have been modified by the developer and the original code is not available anymore. In general, it is not recommended to rely on decompiled code, as the results may not be reliable or accurate. If you need to make changes to your Arduino project, it is best to start with the original source code.

@@Ciiads asm to hex,can use avrdude or xloader?

[@Ciiads]

@ocang alan ocang asm is just a source code. Just compile the source code then you will get the hex file and it is the compiled file that is understandable for every programming softwares that build for. I don't know about how or where did you wrote the source code but there will be always have an option for compiling your source code on the same ide that where do you wrote the code.

It's not possible but it will when you find a decompiler for it, and i didn't find any, even when you find and decompile the decompiled source code is very different than the original source code and it's very hard to understand.

@@Ciiads Hi, I upgraded the atmega328p LCR Test Meter Firmware same as your tutorial but it doesn't work. I've tried different hex and eep files but unfortunately it doesn't work. like an empty device now how can i fix have you any idea ? Thnks

[@Ciiads]

@Zasa Saza Sorry for your situation but No way. this is the way to program avr chips and read back hex file,setting fuse and lock bits etc . reading the chip that is only possible when the chip wasn't protected , Arduino's are not protected . Make sure, first of all,make an arduino as an isp programmer by uploading arduino isp sketch to it and wire this board to the target arduino 10 to reset, 11 to 11,12 to 12, 13 to 13, 5v to vin, gnd to gnd Where is your problem happens? reading hex file from arduino or writing hex file to arduino? did you configured the fuse and lock bit configuration right? What is the message showing on the black window of avrdude when programming? Can you forward the circuit diagram and hex file that you having trouble, let me check and i will figure it out don't worry i will help you and reply you the solution. My contact [e-mail] If you want to just burn hex file to arduino the program called xloader will do the job. Which is very easy just select board type and connected port then just browse hex file click upload that's it. Few Simple steps. Download xloader : mega.nz/file/37AWwCgb#GIPCwiRaSYPW6kNxVA10p77ufQeL40tuPJ6fGJjcOjU If you want to know why are you struggling with avrdude and my tutorial. i have no idea about what you done there please forward the hex file with circuit diagram to my contact . Let me check and verify and i will reply you the solution don't worry I'm with you we can fix that 👍

[@Ciiads]

I got your screen shot in my mail in my observation you didn't selected the currect programmer type select programmer type to arduino. And follow the video with out a single seeking because everything is important. If your lcr meter running at 16mhz then keep my same fuse and lock bit configuration and don't forgot to check the box next to it while programming Please check my reply on your mail 👍 I'm waiting for your successful message❤️❤️😊🤝👍
