Hello everybody.
I am building a dmx usb device, for controlling stage lightning with a laptop. I designed my own version of pcb for **broken link removed** device. There is a hex file for microcontroller on website, but I don't know which fuses must be burned on atmega. Now I am wondering, is it possible, that information about fuse bits is in hex file already? Otherwise, is there any "standard" for this microcontroller, which fuses must be burnt? Any "ordinary" stuff?
Thank you
 

I read atmega with my isp programmer and apparently it was empty, which is strange, don't you think? Aren't atmega32u4 chips factory loaded with boot-loaders? Anyway, I burned a boot-loader for flip on it and successfully programmed firmware.

At least with the WinAVR compiler you can add specific directives on source code for configuring those fuses, so that this information will be stored on the generated .hex file. anyway you have to check if the programmer software is really loading it to its workspace.
