How to load programs to an Arduino UNO from Atmel Studio 7 Meet Atmel Studio 7!!! So you want to have a friendly IDE to encode your projects in arduino?
This instructables is usefull if: * you've got your arduino with atmega168 and you bought an atmega328 at you local electronics store. It doesn't have an arduino bootloader * you want to make a project that doesn't use arduino - just a regular AVR chip (like the USBTinyISP) - you have a clean attiny2313/attiny48 etc that you want to burn firmware on. Normally you would have to have an ISP (In System Programmer) like USBTinyISP to program your new chip. Having the arduino you can teach it to be a programmer thank to a great work done by Randall Bohn. He created - an arduino sketch that works like a programmer. There are two ways to connect your Arduino to program a chip.
You can plug your avr chip to a breadboard and connect 5v and GND to the respective pins (check the datasheet!) + a pullup resistor to reset and wire pins from you arduino to the chip. These are the lines on Arduino and their function 13 - SCK 12 - MISO 11 - MOSI 10 - RST (Reset) Or you can make a 2x3pin ISP header that you can plug into a board that provides one (another arduino board). The pinout for the ISP header is on the third image There are 3 leds to indicate the status of the programmer. Pin 9 - blue led - its the hearbeat of the programmer.
Pin 8 - red led - indicates an error pin 7 - green led - indicates that the programming is taking place (i was lazy so i didn't match the colors in my setup) Here are the drawings made in You can alsa make a MEGA-isp shield. Yaroslav Osadchyy designed the shield in eagle. You can get the eagle files on his site: Attachments •. To use with avrdude (and all GUIs that use it) you have to select the 'avrisp' programmer. The safest bitrate is 19200. To test your your new atmega168 from commandline try: $ avrdude -p m168 -P /dev/ttyUSB0 -c avrisp -b 19200 /dev/USB0 is the port that arduino is connected to my linux box (your's may be com5). This can be checked in arduino IDE in Tools ->Serial Port.
You should get: [kabturek@hal-9000 ~]# avrdude -p m168 -P /dev/ttyUSB0 -c avrisp -b 19200 avrdude: AVR device initialized and ready to accept instructions Reading ################################################## 100% 0.13s avrdude: Device signature = 0x1e9406 avrdude: safemode: Fuses OK avrdude done. That means everything is ok. If you get errors - check the last step. The USBTinyISP is a great programmer from LadyAda thats really cheap - 22$. I had a spare attiny2313 and some parts so i decided to make one myself. If you don't have any experience in making PCB i advice you buy the kit cause it's higher quality than you can make yourself:).
At least buy the PCB if you want to build one. You can get it from.
Connect the ATtiny2313 In the last picture you can see the attiny2313 with the pins used for ISP in red. The picture is from. Burning the firmware: Unpack the USBTinyISP firmware.
Go to the spi dir and run $ avrdude -p pt2313 -P /dev/ttyUSB0 -c avrisp -b 19200 to check if everything is ok with the chip. Now set the fuses: $ avrdude -P /dev/ttyUSB0 -c avrisp -b 19200 -pt2313 -U hfuse:w:0xdf:m -U lfuse:w:0xef:m Now you should attach the 12mhz external oscillator to the chip. And burn the firmware: $ avrdude -B 1 -pt2313 -U flash:w:main.hex -P /dev/ttyUSB0 -c avrisp -b 19200 Voila. Your attiny2313 has the USBTinyISP firmware. Connecting I cheated a bit cause i used a RBBB to simplify the connections. The schema is on picture #2. If you use 2 arduinos use the picture #3 and connect the ISP pin to the ICSP 2x3header on the second(slave) arduino.Only connect the usb power to the first board.
The GUI way This is a little tricky cause you can't just use Tools->Burn Bootloader ->w/ AVR ISP cause the default speed is too big for mega-isp. Avrdude errors: avrdude: ser_open(): can't open device '/dev/ttyUSB0': No such file or directory You have the wrong port (-P) specified or your arduino isn't connected. Check the connection avrdude: Device signature = 0x000000 avrdude: Yikes! Invalid device signature. Double check connections and try again, or use -F to override this check. This is kind of general error.
Usb Vid 090c Pid 1000 Rev 1000 Demo. Your chip isn't recognized. Check the connection on the board (GND/5V connected to pins?) You will get this error when your chip is configured to use an external oscillator and it isnt working (there isn't one or it isn't oscillating properl - 22pf caps missing?). There is an alternative set of instructions that works if you have an Arduino Uno and want to transform it into an universal programmer for any stand alone AVR.
Read this tutorial: 'Arduino Uno R3 as a true ISP programmer for any Attiny and Atmega AVR' see: • • No boot-loader has to be first loaded into your target AVR. You can simply program the Attiny or Atmega micro-controllers, existent on the breadboard, directly with the hex file generated from the source code you wrote (Blink a led, for example).
ATtinyCore (Universal) works with all versions of the official IDE (from arduino.cc ) from version 1.6.3 onwards. For boards manager installation, 1.6.4 or later is required. Due to serious bugs, 1.6.6, 1.6.7, 1.6.8, and 1.6.10 are not recommended. Version 1.8.5 is recommended.

This core can be installed using the boards manager. The boards manager URL is:
http://drazzy.com/package_drazzy.com_index.json
- File -> Preferences, enter the above URL in 'Additional Boards Manager URLs'
- Tools -> Boards -> Boards Manager...*If using 1.6.6, close boards manager and re-open it (see below)
- Select 'ATTinyCore by Spence Konde' and click 'Install'.

Due to a bug in 1.6.6 of the Arduino IDE, new boards manager entries are not visible the first time Boards Manager is opened after adding a new boards manager URL.
Option 1: Download the .zip, extract, and place in the hardware folder inside your sketchbook folder (if there is no hardware folder, create it). You can find/set the location of the sketchbook folder in the Arduino IDE at File > Preferences -> Sketchbook location.
Option 2: Download the github client, and sync this repo to the hardware subfolder of your sketchbook folder.
