Programming:
Software Preparation:
Start by installing the Atmel Flip software including the Java Runtime Environment if you do not already have this installed.
Find the directory where you have installed Atmel Flip for example (C:\Program Files\Atmel\Flip 3.4.1) open the USB folder and copy the file libusb0.dll
and/or libusb0_x64.dll to the folder named bin. (You may need to disable 'Hide protected operating system files' for this step'
The software preparation is now done and you have also saved yourself time solving a simple problem, Good Job!
Hardware Preparation:
The next step is to plug the USB device into your PC. After some loading of drivers you will be greeted with a folder containing various demo packages
and so on, go ahead and copy these files to your computer if you wish to make a backup.
Now you'll need to put the AVR USB into Programming mode :
1. Hold the RST and HWB buttons (2 buttons)
2. Release the RST button.
3. Release the HWB button
At this point windows should start prompting you for drivers so direct it to the USB directory in your Atmel Flip folder for example
(C:\Program Files\Atmel\Flip 3.4.1\usb) and you're done.
Greets!
