Upload Hex files with AVRdudess GUI Graphical User Interface

Download AVRdudess. This project uses the portable version that does not permanently install. Donations are welcome.

Open AVRdudess program

Unzip and go into folder. Look for avrdudess.exe and double click.

A warning pops up. Click More info then Run anyway. This is only for the first use.

Select Arduino as programmer(-c), look under Port(-P) for a com port with a number. You may have to look in Device Manager to find the port number. Select MCU(-p) ATmega328P for an Arduino Uno board.

External programmer devices may be found by selecting usb. Click Detect and see if there are messages at the bottom. If you use the command line version you will recognize these terms.

Find Upload File

Go to Flash and click the box with ... dots. Navigate to the hex file you want to upload. Arduino IDE outputs usable hex files with the menu command Sketch->Export compiled binary. Either of these files will work.

This is a really good program if you are working with Atmel Studio, MPLab or Code::Blocks IDE and don't have the programmer setup. AVRdudess will upload compatible hex files from those suites.

Program!

Click Program! and watch your file upload progress.

The Arduino Uno board at port COM7 is now blinking.

Why use this program?

• Easy GUI Graphical User Interface
• Uploads files from Atmel Studio, MPLab, Code::Blocks
• File read. Download hex file from programmed device.
• Works with many MCUs not available in Arduino IDE
• Better success with inexpensive programmer devices
• More programming devices
• More flexible options for file type, upload speed
• Faster upload than Arduino IDE
• Access to EEPROM and fuse settings. Caution!
