First we need to turn the Arduino Nano in to a programmer. This is done by uploading the ArduinoISP sketch. The ArduinoISP sketch is part of the Arduino software package and can be found in the examples folder.
Arduino Nano as an ISP Programmer
Load the example Blink sketchMake sure the board to be programmed is the Atmega stand alone and the programmer is set to Arduino as ISP.In the main menu select Upload Using Programmer (or press Ctrl+Shift+U) and the Blink sketch should upload.Note that you need to use the menu option not the upload icon.
resp=0x00 means the programmer cannot communicate with the chip. This normally means the connections are not correct (check the wires, especially VCC and ground)or you tried to upload the sketch using the Upload button in the IDE. Remember to use the File menu option
Hi, I like your tutorial!I want to use my nano to program a atmega16 chip. I need to load a .hex file to the chip. Is it possible to do it following this tutorial? I am just a newbie to programming btw. However, I didnt find any tutorial on youtube, so I hope you can help me.Thanks.
I would be interested in working on such a project. I am a retired programmer with 35+ years of experience working with microprocessors. I have done several arduino projects. Email me if you are still looking for help.rdgarton@email.com
Hi Martyn, thank you for your clear and concise article. I never used ICSP programmers with arduino sketch. I have a basic question: I would like to dedicate all the flash memory of the MCU datasheet to the sketch. I would like to use the Atmega32u4 as it has 25% more sram than the 328P although less flash is available from the internal USB. If my design is standalone, the USB would not be necessary other than to program from arduino with bootloader. How could I use this Nano programmer to program the Atmega32u4? Could I have 32768 Bytes of flash for a sketch? Would the tx, rx pins be available as rs-232 for my standalon layout? Thank you.
I've bought a few ATMEGA328P-PU's, and I've been trying to install a bootloader onto them for the last many hours with no luck. I've been using my arduino nano, and have both tried uploading via arduino uno and breadboard to no avail. I have watched countless of videos and read countless of threads, and from what I've gathered, it should be possible to burn a bootloader onto a 328P-PU with just a nano, but everytime i try i get an error. I've mostly been getting the "Expected signature for ATmega328P is 1E 95 0F" error, and yes, I have tried changing the value in avrdude.conf.
Yes, I have tried the Arduino as ISP. I've been using my nano to try and burn a bootloader onto a 328PPU Chip, and as I mentioned, I've tried both plugging the chip into my Uno and a breadboard.I'm in school right now, so I'll just copy the exact error somewhere from the internet.
I can now burn the bootloader, and it gives me a long successful message.Now I'm also able to upload sketches via the programmer!Just one issue. When I upload the blink sketch, everything works good on the breadboard and the LED connected to pin 19 works, but when I plug it into my Arduino Uno, the sketch doesn't work and the BUILTIN led doesn't light up at all, and the reset button doesn't work. Do you know why that is?

I did as you described, unless I have to use the same port as well? I'm guessing that doesn't matter at all. I use a different programmer as well, of course, as I can't use "Arduino as ISP" when uploading a sketch on my Uno...
Trying to use Arduino-as-ISP for programming a MINI PRO clone with a NANO clone.Setup is exactly as described in the ArduinoISP tutorial with USE_OLD_STYLE_WIRING enabled.The NANO (programmer ) have the 10uF reset override capacitor.The programmer is running with heartbeat LED OK.When I use this setup to program a modified BLINK sketch I get the screenshot below :
Yes they had a bootloader before.But the fact is that the "burn bootloader" command actually ran to an end with proper signaling from the "ArduinoISP LEDs" and with a proper end message.On the contrary, any attempt to upload a sketch gives the "programmer not corresponding" message. And red error LED.
Thank You for your suggestions.I tried your approach. Made changes to ArduinoISP as shown below.The result was the very same. Burn bootloader worked. But upload failed with the same response:avrdude: stk500_recv(): programmer is not responding.
Hi ALL; I sourced 2pcs of whats supposed to be NANO, but uses CH340 and ATMega168and is already (supposedly ) bootloaded.Installed driver for 340 from Sparkfun, opened arduino and selected:Arduino Nano as board, atmega168 as processor, Arduino ISP as programmer.Uploaded BLINK and was successful. ( Didnt upload BOOTLOADER ).
Wacky that you got wrong chip before doing burn bootloader... or do you mean burning the mini ore bootloader yo 168? I like those 168 nanos, because they seem to be able to cram everything into top of board (so it sits flat on surface. Unsure why 328p namos arent available eith that layout...
Conveniently, you can use a Nano as a programmer for burning a bootloader and your code onto a virgin ATMega. I found this excellent blog post by Martyn Currey that lays out how to go about this really clearly and concisely.
I recently bought a few Atmega328PU chips to use in some project. Its better to use these bare ICs in the circuits instead of putting the whole Arduino Uno or Nano board, as their cost is higher. But the problem with bare Atmega328 ICs is that usually there is no bootloader installed in them and you need a saperate programmer to program them before you put them in your circuits.
Right before uploading the code, we need to burn the bootloader to the brand new ATtiny85 chip with the following settings. Once bootloader is ready, upload the code, and make sure to select programmer as Arduino as ISP.
Not very long ago, programming firmware on microcontrollers was somewhat more difficult.Proprietary toolchains, dedicated (and expensive) programmers, and outdated physicalinterfaces were the norm. Programmers and SDKs typically cost thousands, as they wereaimed squarely at embedded systems professionals. The hobbyist did not even get a look-in.
I only recount this to illustrate how far things have come and how lucky makers andhobbyists are to have access to the Arduino system. For the most part, you do not haveto concern yourself with device programmers, fuse settings, etc.
There are several things that make an Arduino an Arduino, not least of which is thebootloader. It is the bootloader that allows you to program the microcontrollerwithout a dedicated programmer.
In-System Programming, or ISP, is a generic term in embedded systems that meansre-flashing a device without removing it from its target system. When ISP-capable devicesfirst arrived on the scene it was like a miracle. Previously, for every tiny change to thecode, the target system had to be opened up, the device levered out of its socket andput into a programmer attached to the development system. 2ff7e9595c
