HV_PROG is the Dragon and DEVICE the Atmega328p.Īfter connecting everything you should end up with something like this.įor a quick reference see the Atmega328p pinout here. Build on a bread boardĬonnect the Dragon to the Atmega328p following this wiring. You can directly put the Atmega328p on the Dragon board, but if you use an external bread board you can easily put more components on that board and do much more testing. That means you can’t use the Atmega328p on your Arduino anymore ! So just buy a seperate microcontroller and keep your original Arduino working. Connect the Atmega328p to the AVR Dragon boardīefore you use the original Atmega328p microcontroller from your Arduino keep in mind that you will loose the bootloader inside the microcontroller. It is possible to use an Arduino board together with Atmel studio, but with this board you can also program different microcontrollers. The cheapest board with some debugging options I could find is the AVR Dragon board ( ). I had to turn off my virusscanner to avoid blue screens so i decided to keep using the older version 6.2 (AS6) You can download it from The AVR Dragon board I tried to use the latest version 7 from Atmel, but i run into a lot of blue screens. With Atmel studio it is possible to program a wide range of AVR microcontrollers which will be usefull in the future. Besides that, it’s the original IDE from AVR, the maker of the Atmega328p microcontroller (used by Arduino). The following related articles show how to connect a programmer (AVR Dragon and AVR ISP mkII) to an Arduino board and restore the bootloader using Atmel Studio 7 on an Arduino Uno and Arduino MEGA 2560.The Arduino IDE is great, but with Atmel studio you can do more including easier debugging. load the Blink sketch to flash the on-board LED Related Articles
Start the Arduino IDE and load a sketch to test that the bootloader is working, e.g. Click the Program button Arduino Uno Fuse Setting - click for a bigger imageġ4.
After programming has finished, click Fuses in the left paneġ2. Click the Program button Burning the Arduino Uno Bootloader - click for a bigger imageġ0. Browse to the bootloader hex file using the. Click Memories in the left pane of the dialog boxĨ. You can click the Read button under Device signature to make sure that you can connect to the ATMEGA328P microcontrollerħ. In the Device Programming dialog box, select AVRISP mkII in the Tool drop-down box, ATmega328P in the Device drop-down box and ISP in the Interface drop-down box Atmel Studio Interface Settings - click for a bigger imageĦ. In Atmel Studio, click Tools → Device ProgrammingĤ. Connect the hardware as described aboveģ. The bootloader in this folder that must be loaded to the Arduino Uno is optiboot_atmega328.hex Steps to Burn the Bootloaderġ. In version 1.0.1 of the Arduino software, you will find the bootloader in the Arduino folder:Īrduino-1.0.1\hardware\arduino\bootloaders\optiboot\ The bootloader is included with the Arduino IDE software.
Power up the Arduino either from the PC via a USB cable or by an external power supply. Pin 1 is marked on the AVRISP connector and on the Arduino header. Make sure that you connect it the right way around. Plug the AVRISP ribbon cable connector into the 3 by 2 header on the Arduino board. Plug the AVRISP mkII USB connection into a spare USB port on the PC. The best solution to this problem is to use Atmel Studio to burn the bootloader, rather than removing Atmel Studio and its drivers. The Arduino IDE displays the error message:Īvrdude: usbdev_open(): did not find any USB device "usb" If you have loaded Atmel Studio on your PC and you try to burn the bootloader to the Arduino using the Arduino IDE, you will get an error message in the Arduino IDE because of a driver clash between Atmel Studio and the Arduino IDE drivers.
