alright, I just started using winavr. I followed the document provided by Colin O'Flynn, "Downloading, Installing and Configuring WinAVR".
I successfully downloaded the latest winavr version released last may, inputted the sample source code provided in the document. I clicked the "make" option in the programmer's notepad, and it was alright. But when i clicked the "program", an error was displayed.
"avrdude.exe - Unable To Locate Component"
"This application has failed to start because libusb0.dll was not found. Re-installing the application may fix this problem."
