AVRDUDESS 2.4: The Ultimate GUI for AVRDUDE

Introduction

AVRDUDESS 2.4 is the latest stable release of the popular graphical front-end for AVRDUDE (AVR Downloader/UploaDEr). It provides a user-friendly Windows interface for programming AVR microcontrollers (like Arduino, ATmega, ATtiny, etc.) without needing to memorize command-line syntax. Version 2.4 brings several quality-of-life improvements, bug fixes, and enhanced hardware support.

Drag-and-Drop Uploading: Simply drag a .hex file onto the interface to prepare it for uploading to the flash or EEPROM memory.

5. Expanded Programmer Support

Supports over 100 programmers: USBasp, USBtinyISP, Arduino as ISP, AVRISP mkII, Atmel-ICE, STK500, parallel/serial port programmers, and many more.
Custom programmer configuration for unsupported hardware.
