Graphical microcontroller programming tool based on extended S-System Petri net
Kok Mun Ng, Zainal Alam Haron · International Conference on Computer Engineering and Applications · 2010
This paper presents a graphical programming tool, S-PNGEN that utilizes an extended form of S-System Petri net (SSPN) to express in graphical form application programs written for microcontrollers. The tool allows SSPN-like graphical application program to be constructed easily with a built-in diagram editor. The SSPN application program constructed is internally represented by directed graphs, which is then parsed using context-free diagram and string grammar to check for correct diagram and sentence syntax. Upon successful parsing, the tool automatically translates the SSPN-represented application program into assembly code for a target microcontroller.
