I am new to this forum and have no experience with AVR chips other than I have done some Arduino programming. I was given some hex code for an electronic project. No source code is available because the author is deceased. Electronic project and the code, I am told, worked very well. The code was written for an atmega168 using the Bascom basic compiler. The fuse settings are factory default ie. burning hex code makes no changes to the fuse settings, and it uses the internal clock osc. I am planning on using the arduino as an ISP to burn atmega168 using AVRDUDE.
My question is . . . is it possible to burn an alternate device the ATMEGA328 instead, using the same HEX code?? The atmega328 chips are more readily available and as I understand, has double the flash and ram size.
As I have stated, I new to this forum and AVR, so don't beat me up, if this seems to be a dumb question.
Your advice is appreciated.
