I have set up an IAR compiler and Atmel visual Studio ver 7.0.122
Using Atmel ICE IAR programs and debugs fine
Atmel Studio won't read the device signature but will read the voltage. 5.3vdc
Failed to enter Programming Mode
It fails after I debug with IAR but IAR continues to work.
SO it has something to do with debug fuse but I don't know how to change that fuse from IAR
and atmel studio cant connect to the chip
The dropdown list does not have debug wire only ISP
I realize now the several mega 48's I thought were bricked work using IAR but no longer AVR studio
so I am happy about that.
