Description: This small program is a simple GUI that makes it easy to upload any hex file to the Arduino using AVRDUDE. The program assumes you already have AVRDUDE installed. It is written in C# and .NET. So far the program has only been tested on the Arduino Pro Mini.

  • Before running the program, make sure you can open up a console and run execute avrdude.exe successfully.
  • Make sure you reset your Arduino immediately before attempting to program it.
  • Is the program not working? All it does is run a command similiar to this on the command line: avrdude -F -v -pm168 -cstk500v1 -P\\.\COM4 -b19200 -D -Uflash:w:"file.hex":i
  • may need add path to avrdude config file: -C"c:\utils\arduino-0016\hardware\tools\avr\etc\avrdude.conf" if Arduino IDE installed in "c:\utils\arduino-0016\"
