Thank You very much sir!!! i already have a AVR serial programmer and a usbasp programmer. But my problem is i have downloaded the firmware from http://www.obdev.at/downloads/vusb/USBaspLoader.2012-12-08.zip as it is mentioned in the metaboard's website. after downloading the zip file don't know how to compile and upload the hex file into the controller.
thanks, can you tell me how to use avrdude and winavr?
