Some HELP with programming an Atmega32U4 with ISP
Posted: Fri Jun 24, 2016 6:02 pm
Sooooo I'm at my wits end right now trying to program my test board with the bootloader and eve skipping that and using a compiled hex of the controller code and no matter wtf I do it always give me a verify error at the end about data mismatch.
I had to use my leonardo as an ISP Programmer to reprogram my USB programmer as a USBasp which it did and both the Leonardo and USBasp give me the same error. Then I also have no idea on the fuses and have tried many many combinations using the fuse calculators and default setting and even the bootloader fuse setting in a tutorial :

Still same error and when I plug it in the USB into my PC nothing is recognized like nothing is plugged in, I checked the fuse and the chip itself which is getting the 5v and the chip is recognized in the programmers with the ISP header.
Any help on this? I'm about to solder up another board and throw this thing out the window and see if the new one will have better results.
