I have a arduino Duemilanove and an atmega8 chip. The arduino board is having Atmega328 on it. I have written a code that works fine on arduino. Now I want to transfer that code from arduino to my atmega8 chip. Can I use arduino bootloader to do that?
Thanks in advance.
In theory you can, but there are some things missing at Atmega8, like Timer2 hardware, for example.
So it is possible use the Atmega8, but you need to upload Arduino NG or older w/ ATmega8 bootloader to the chip and check your code (mind the libraries!) for use of hardware that is not present at Atmega8.
To burn the bootloader I am using a Parallel Cabe, like this:
http://arduino.cc/en/Hacking/ParallelProgrammer
And follow the sequence below to burn it:
Choose menu Tools > Boards > Arduino NG or older w/ ATmega8
Choose menu Tools > Programmer > Parallel Programmer
Menu Tools > Burn Bootloader
That's it!

You Can use the old files from arduino for sure and (probably also the newer builds)
But keep in mind that you have only ~7Kb(after the 1K bootloader)
you will need to compile the code as "Arduino NG or older w/ Atmega8"
You can find instructions on how to burn a boot loader here
http://arduino.cc/en/Hacking/Bootloader
And a reference schematics here

Purchased some clone Arduino nanos a while ago and finally got to working with them.
Of the 3 i worked with, 2 of them upload and verify fine.
The third is able to upload (code functions properly), however it fails to read flash data.
this is required to post pastebin
Here is the output from a clone that worked:

Here is the output from the one with the issue:

What I've done so far:
Reflashed bootloader from working Arduino as ISP
CH340 driver installed
Used (old) bootloader when uploading
Tested on both Linux and OSX
Any suggestions or insight would be much appreciated.
If you have a working UNO or similar board, you could try uploading the bootloader using the Arduino IDE (https://www.arduino.cc/en/Main/Software), and see if you get different results. Sorry, I'm not familiar with using avrdude.
The link on sparkfun gives really good instructions on how to accomplish this task. Scroll about half-way down to where it says Upload Arduino as ISP https://learn.sparkfun.com/tutorials/installing-an-arduino-bootloader/all
Basically, you connect the UNO to your target as shown in the link, then select ArduinoISP in the examples menu, select the COM port and board, and upload the sketch. Then you select your target board in tools, and select Programmer, Arduino as ISP in tools, and finally, Burn Bootloader in tools.
I've had 100% success burning blank Atmega chips using this method.
I'm having a problem with ESP8266 in programming part.
I'm using Arduino Uno and have thousand times run programs.
It's has been my second day in completing my esp8266 simple fully function circuit
My current problem is :
ESPwifi library has many error even I download it from official github source code
So, I decided to use WIFIESP library and it stuck at TIMEOUT/NO WIFI/NO MAC ADDRESS
I cannot use pin 0 & 1 because a wire stuck in it.
I have search everywhere to solve my problem even tough needs alternative ways I will at least doesn't required NEW HARDWARE.
Reupdate : 08:18 PM 4.3.19
I just want steps without need AT firmware & able to post data to websites
I don't want extra boards EXCEPT:
Arduino UNO
ESP8266-01 (small one with 8 pin)
Windows 10 with arduino IDE latest version
I'm not sure what your real problem is, but here is my solutions:
In case you haven't install the esp8266 boards for the arduino IDE yet, then you should install it first. The installation instructions is documented on GitHub. Here is the snippet to install ESP8266 boards on Arduino IDE:
Start Arduino and open Preferences window.
Enter http://arduino.esp8266.com/stable/package_esp8266com_index.json into Additional Board Manager URLs field. You can add multiple URLs, separating them with commas.
Open Boards Manager from Tools > Board menu and install esp8266 platform (and don't forget to select your ESP8266 board from Tools > Board menu after installation).
ESP Libraries needs Arduino Core Library to work. If you haven't install the board yet, then you will get many errors.
hope this help.
I have a nodemcu v3 and I'm trying some basic stuff
I installed the esp8266 board in Arduino IDE and then I uploaded a blink example.
But now I'm trying to upload Lua code using ESPLorer but I doesn't work properly. I press in open and set the baud rate to 115200 but I just get some infinite Chinese letters.
Should I reinstall the firmare or something?
There is a very good answers at https://stackoverflow.com/a/43509569/131929 and https://stackoverflow.com/a/47510019/131929.
Should I reinstall the firmare or something?
First you should make up your mind whether you want to conveniently program in Lua or whether you want to stick with Arduino (running on the NodeMCU-clone board). It is an either-or question. Flashing on of them to the module will erase the respective other.
And no, in case you want to use the NodeMCU firmware, you should not use those outdates binaries from 2015. Build a recent version conveniently in the cloud: https://nodemcu.readthedocs.io/en/latest/en/build/.
P.S. if you're interested why I call yours a clone board you may want to read https://frightanic.com/iot/comparison-of-esp8266-nodemcu-development-boards/ from yours truly.
You must erase the flash of your NodeMCU before a new upload. If you ignore that, your software don't run appropriately. To do that, I'm using esptool:
python esptool.py --port COM9: erase_flash
In that example COM9: is the name of my USB/serial interface.
After that you can flash for example your ESP8266 with that line of code to add a boot part:
python esptool.py --port COM9: write_flash -fm dout 0x00000 boot_v1.5.bin
Use the preview line of code and adapt it to upload other parts of the map of the flash memory.
I'm trying to build a midi controller using an Adafruit Trellis and an arduino leonardo. When it comes to run the code, the uploading status freezes and doesn't complete. I've tried to run a hello world using both an arduinoleonardo and a uno but I still had the same problem. I've deleted the IDE, reinstalled it but nothing has changed. I think it's a driver problem but I actually don't know what to do.
Assuming your Uno is good (no defect), try to plug into a different USB port and try different COM #. Also make sure that you are selecting the correct type of Arduino.
I purchased this extruder controller board and this board to connect it to the computer. I am following the tutorial above in trying to set it up. We successfully did the boot loader part of that tutorial and the DEBUG LED is flashing. I followed the tutorial all the way up to uploading the program. The Arduino software does not find it in "Tools -> Serial Port", but allows me to burn the bootlegger. The only options are a couple bluetooth devices I have connected, none of which are useful.
I am only aware of windows drivers for the ISP programmer board you're using. When I've ordered funky hardware off of eBay with a non-existent or difficult-to-find OSX driver, I've had success running Parallels. This is a funny work-around, but it might be your best bet -- many folks over on the Arduino.cc forums are having the same problem.
So: Curse the Gods. Buy parallels. Install windows. Install Atmel's official drivers. Burn your bootloader. Get back to building.
As always, if a serial port isn't showing up in the Arduino IDE, run the following command from Terminal:
ls /dev/tty* | grep 'usb'
