Utveckling av inbyggda system med grafisk programmering

Sammanfattning

The increase of complexity in embedded programming is forcing the development of higher level programming

languages. These languages not only consist of traditional text based programming but also with graphical programming

languages such as the programming language G from LabVIEW which is developed by National Instruments and have

been around since the mid eighties. However since 2004 this language has also been able to program embedded

hardware, using the modules LabVIEW SDK and LabVIEW for ARM. This thesis shows how LabVIEW for ARM converts its

graphical language G to C and then how C is flashed into the microprocessor. The thesis also takes up the pros and cons

of using G for embedded development. The conclusion is that G is extremely useful for people without embedded

knowledge that still want to develop embedded solutions. For customers with textual programming experience a

time/cost analysis should be performed to see if G is more cost effective. The disadvantage is that LabVIEW SDK only can

be used with 32bit processors and LabVIEW for ARM is even more restricted because it can only be used with ARM

architecture processors. Another disadvantage comes into play if the user chooses to use a microprocessor which is not

sold distributed from National Instruments because then a framework is needed to be constructed before usage,

however this thesis shows in detail how such a framework can be developed.
