Like someone else said this is exactly what I was looking for, though I don’t know if they’re a newbie like myself. Clear, concise, simple language that even I understood. Thank you.
You also can upload sketches to your standalone avr.chips in the same configuration you used to burn the bootloader. just select your target chip in the menu and then choose sketch -> "upload using programmer" (ctrl+shift+u), in this case your "arduino as isp" will send your sketch to your target chip ;)
RESPECT absolutely the folers containing the standalone files!!! I lost 3 hours of my life before see that. There was the "containing" archive folder to remove... (Breadboard1-6-x)
I have two GM328 transistor testers (from Aliexpress), based on ATMEGA328P (28 pin DIP). During brightness adjustment (through the menus) they became dark (one after the other). The consumption is fine, the clock is running (8 MHz crystal), the LCD control pins are active (transitions seen by scope) i.e. the hardware is fine. I presume the manufacturer locked the code. A soldered wires from the board pins 1(RST), 2(RXD),3(TXD), 7(+5V), 8 (GND) and terminated them with a header, fitting my FTDI (GND,CTS,Vcc,TX,RX,DTR), taking care to cross link TX, RX (of the baord) to RX, TX on the FTDI. I also inserted a 0.1uF cap in the DTR to RST line. On the board there is just a 10k pull up on RST. When trying to load a sketch via FTDI, it cannot open the port. I guess there is no boot-loader either. How do I determine if there is a boot-loader and if the code is locked? Do I buy new chips or somehow unlock the present ones. Apart of FTDI, I have several NANOs if that is of help. Thanks Plamen
Thank you for this tutorial. You have done a good job of clearly explaining all the necessary details. I will probably try this so that I can simplify my project which is to create a remote 3V battery-powered sensor. I am actually using the 16 mHz 5V option which requires a lot of additional components and additional battery. Well done!!
I tried it and was able to burn the bootloader but with the following warning (with or without the crystals&caps): "avrdude: WARNING: invalid value for unused bits in fuse "efuse", should be set to 1 according to datasheet. This behaviour is deprecated and will result in an error in future version. You probably want to use 0xfd instead of 0x05 (double check with your datasheet first)." I can burn the standard bootloader for 16mHz Arduino board configuration. Do you have that WARNING too? I wasn't able to catch the message on your video.
To AlexInFlatland: As nothing was working even with the blink sketch and the avrdude warning, I used www.gammon.com.au/forum/?id=11637 . All works fine. ATmega328p 8 mHz internal oscillator and everything at 3.3V. Thought you might want to know and for what it's worth.
I have one question What if I burn bootloader of the Atmega328 on arduino Board and then use it on breadboard after removing it from the arduino board onto the breadboard? Pls reply I need for my Project
The essential download link for the 8 MHz breadboard is missing. And it’s much easier to also download the sketch the same way you downloaded the bootloader.
Hello. Is it possible for me to upload the sketch to the external atmega328 (attach on the breadboard) without removing the stand-alone or orginal atmega328p from the arduino uno? Cuz I heard that removing it from the arduino will ruin it. Thank you for your response
Dear......Can You help me in loading bootloader into a Atmega328 u . I use your procedure but getting following error Arduino: 1.8.19 (Windows 10), Board: "ATmega328 on a breadboard (8 MHz internal clock)" Error while burning bootloader. avrdude: Expected signature for ATmega328P is 1E 95 0F Double check chip, or use -F to override this check. Invalid library found in C:\Users\Aleemuddin\Documents\Arduino\libraries\Digistump: no headers files (.h) found in C:\Users\Aleemuddin\Documents\Arduino\libraries\Digistump This report would have more information with "Show verbose output during compilation" option enabled in File -> Preferences. Please help me.......
A question for you Alex: Do you see any way to use the existing oscillator from the arduino UNO pcb for the ATmega chip for this operation? Or just placing the ATmega chip in the UNO for the burning of bootloader and programming?
Hmmm, as far as I'm aware, you can't program a bootloader while the ATmega is in the Arduino. At least I haven't been able to find anything on the subject. And I think you wouldn't be able to use the onboard oscillator as well, since there are no direct pins on the Arduino output connected to the oscillator itself. That is, unless you would to desolder it, but that kind of defeats the purpose.
I have done just as you did(with a blank chip), and the bootloader burn was completed but IDE sent me a warning "***failed; avrdude: WARNING: invalid value for unused bits in fuse "efuse", should be set to 1 according to datasheet This behaviour is deprecated and will result in an error in future version You probably want to use 0xfd instead of 0x05 (double check with your datasheet first)", tried to burn the chip again, and it says "Invalid device signature". nothing works. PLEASE SAVE ME FROM MY STUPIDITY!
As far as I'm aware things should work. I've used this setup for a few projects myself. Although that might depend on exactly what your project involves. The Arduino board DOES include a few more components, so I can't say with a 100% certainty that some of those aren't required for some of the pins/functionality.
i am not gay but i mmmm ....just want to say i love you man .... your video made my day ... after many unsuccessful attempts i had lost my hope but. after watching your video i successfully burned the bootloader... thank you..... ( sorry for my bad English )😅
Sorry about that! I think RU-vid removed my external links. I re-uploaded them to my website and updated the description with the new links. Thanks for watching!
Thank you for catching that! I think RU-vid must have removed them as they were external links. I uploaded the files to my website and updated the description with the links. Let me know if those work out for you.
Thank you very much for your quick response. You can find these files on the Internet but then you don’t know if they are the right ones or will mess things up. I want to do it two ways: Using the file you have provided and also by setting the Fuse Low Byte using Avrdude. I love this video. The content is precise and comprehensive and very well explained. Thank you for your hard work and for sharing it.
Hey Jimmy! Are you referring to needing them during the setup process? Because after you set all of this up, you essentially just need to provide power and no other components really.
