#endif statements for conditional compilation.Ĭ18 doesn't support the 12 and 14 bit cores of course, but other compilers for those cores would have their own methods. A compiler is supposed to ignore pragmas it doesn't understand, so you could do the following:Īnd each compiler should ignore the pragma it doesn't understand (although I haven't tried this). For example, CCS doesn't support multiple compilation units (no linker) so code written for CCS needs to be structured differently from other compilers.įor a config bit example, CCS and C18 use different pragmas for configuration bits, so a somewhat portable solution should be possible. There are generally too many differences between compilers for full portability anyway. ![]() You would have to search the documentation for each compiler you wish to support to determine its method. Some users may wish to install both Atmel Studio 7 and AVR Studio 4.19 on the same computer. ![]() This may be useful if the user wants to preserve disk space or has a slower computer. There is no truly portable way to do this. CodeVisionAVR can be also used with its own IDE and the debugger, without having to install Atmel Studio. ![]() ![]() Configuration bits are not a standard part of C, so each compiler handles it differently. Getting Started with the CodeVisionAVR Extension for Atmel Studio 6.1 After the debugging tool was selected, the debugging session actually starts: The simulator first executes the low level startup initialization code, which consists of filling all RAM locations with 0s, initializing the global variables, data and hardware stack pointers.
