Ok so I got the thing progg'd with AVR Studio 4 real easy.
But now I want to change a couple of things.
So I did what it says and installed AVR 5
I opened config.h and changed a couple of things via notepad then closed and saved the edited config.h file back in its original place.
The file now has a red ! Next to it.
Followed the instruction to compile and it returned no errors but I notice that now the output hex file has a red ! Next to it.
Is this normal or at least ok ?
I changed the coordinates to suit google and that seems to change on the osd screen.
I selected only two of the home pos set options ie
#define HOME_SET_MIN_SATS 4
I had 9 satellites but still got no home position ??
What have I missed here
Thanks in advance
