The Keil µVision environment allows users to develop a complete application. Its project management features allow the building of projects which include multiple code files with mixed assembly and C code. It also allows the inclusion of library functions and predefined header files. The µVision3 software includes a limited version of the ARM ADS compiler. Full support for the Open source GNU toolset is integrated with the IDE. Since the GNU toolset is open source, there is no restriction on the code size that can be compiled in the evaluation version of the Keil IDE. The one limitation is in the debug of code where it is limited to 16kB in the evaluation version. There is no limitations in the full version available from Keil software. This toolset features both a simulator and a debugger which feature full support for all the ADuC702x peripherals. Code can be debugged in system using the U-Link or mIDAS link JTAG emulator that is supplied with the development system. Users who wish to use the ARM Realview tools can target the ADS compiler using this IDE.
