![]() Things will be clearer as you progress further. If all this seems confusing at this point, you may simply follow steps for compiling programs for the LPC214x. Later articles will cover this in detail when you have compiled some basic programs and are comfortable with compilers. These are then combined by a linker script in a way that suits the target platform. However it is mentioned for the sake of completeness – the compilers convert programs to assembly files that are in turn converted to object files. ![]() Luckily, most of this is automated and you do not need to dive into the finer aspects for compiling basic applications. ![]() Linking and Further StepsĬompiling programs for a microcontroller goes way beyond just running the compiler. These variables or arguments include, but are not limited to architecture type of the target system, memory information of the target system, clock frequency, output file format, and code optimization preferences. The variables or the arguments that a typical cross compiler takes are related to what compilation rules you want to impose on the output binary file or executable. Cross compilers are sometimes difficult to set up because the compiler has no information on the active configuration of the target platform and needs to know certain parameters before it is able to compile code for the target.Ī similar nomenclature is often followed for assemblers: native- and cross-assembler. The system running the compiling tool is called the “host platform”. The device you are programming will be called the “target platform”. When output binary files are supposed to run on a system that does not have the same architecture as the host running the compiler, the code is said to be cross-compiled. For example, a native compiler will produce output binary files that will run on x86 if the compiler was running on an x86 platform. For example, the GCC that you use to compile C programs to run on your personal computer is a native compiler and produces executables for the same architecture. In computer terminology, a native compiler is a compiler that compiles source code for the same architecture on which it is running. If you have compiled programs from the command line before, you probably already know this. It may take weeks to just get the tool-chain up and running without the right tools to get started.įirst, we go through some pre-requisite concepts of compiling programs for ARM microcontrollers in particular and all microcontrollers in general. The flexible and modular design makes ARM affordable and fast – but at the same time very complex to understand for beginners. You must also have noticed the complexity of the ARM architecture. If you have read the previous article – Why switch to ARM ? Introduction to ARM Micro Controllers – you must have had a basic idea on what makes ARM7 superior to other more commonly found 8-bit architectures.
