Supported MSP430 devicesIt is also possible to implement parts of the application, or the whole application, inassembler language. See the MSP430 IAR Assembler Reference Guide.For more information about the Embedded C++ language and Extended EmbeddedC++, see the chapter Using C++.Supported MSP430 devicesThe MSP430 IAR C/C++ Compiler supports all devices based on the standard TexasInstruments MSP430 microcontroller, which includes both the MSP430 architectureand the MSP430X architecture. In addition, the application can use the hardwaremultiplier if available on the device.Building applications—an overviewA typical application is built from a number of source files and libraries. The source filescan be written in C, C++, or assembler language, and can be compiled into object filesby the MSP430 IAR C/C++ Compiler or the MSP430 IAR Assembler.A library is a collection of object files that are added at link time only if they are needed.A typical example of a library is the compiler library containing the runtimeenvironment and the C/C++ standard library. Libraries can also be built using the IARXAR Library Builder, the IAR XLIB Librarian, or be provided by external suppliers.The IAR XLINK Linker is used for building the final application. XLINK normally usesa linker command file, which describes the available resources of the target system.Below, the process for building an application on the command line is described. Forinformation about how to build an application using the IAR Embedded WorkbenchIDE, see the MSP430 IAR Embedded Workbench® IDE User Guide.COMPILINGIn the command line interface, the following line compiles the source file myfile.cinto the object file myfile.r43 using the default settings:icc430 myfile.cIn addition, you need to specify some critical options, see Basic settings for projectconfiguration, page 5.4MSP430 IAR C/C++ CompilerReference Guide
