Hi, I want to design some features which require low-level access, which is why I would like to use Keil IDE. Since Arduino DUE has an ARM Cortex M3 CPU, there shouldn't be issues when using Keil IDE, nevertheless, I don't know how to configure my project in order to be able to program the Arduino DUE board via Keil IDE. I.e. I don't know what settings are required in order to make the Keil IDE usable.

Low level access IS available thru arduino IDE. Header files, Sam3x datasheet plus the Graynomad pinout diagram is more or less all you need for getting started with low level programming.
