Dia has special objects to help draw entity-relationship models, Unified Modeling Language (UML) diagrams, flowcharts, network diagrams, and simple electrical circuits. It is also possible to add support for new shapes by writing simple XML files, using a subset of Scalable Vector Graphics (SVG) to draw the shape.
Free and open-source software portal; GNU cflow is a flow graph generator that is part of the GNU Project. It reads a collection of C source files and generates a C flow graph of external references. It uses only sources and does not need to run the program.
Fritzing's schematic view. The software was created with inspiration from the Processing programming language and the Arduino microcontroller [6] and allows a designer, artist, researcher, or hobbyist to document their Arduino-based prototype and create a PCB layout for manufacturing.
The Arduino IDE supplies a software library from the Wiring project, which provides many common input and output procedures. User-written code only requires two basic functions, for starting the sketch and the main program loop, that are compiled and linked with a program stub main() into an executable cyclic executive program with the GNU ...
RAPTOR allows users to write and execute programs using flowcharts. The simple language and graphical components of RAPTOR are designed to teach the major ideas of computer programming to students. It is typically used in academics to teach introductory programming concepts as well. [3]
Simple example of a program in the DRAKON language These examples are real code from an implementation of the Tetris game. The examples are in DRAKON-JavaScript language. The icons (visual primitives) of the DRAKON language define the overall structure of the algorithms. The code snippets inside the icons (primitives) are in JavaScript.
Activity diagrams [1] are graphical representations of workflows of stepwise activities and actions [2] with support for choice, iteration, and concurrency. In the Unified Modeling Language, activity diagrams are intended to model both computational and organizational processes (i.e., workflows), as well as the data flows intersecting with the related activities.
Within the package, a full-featured FreeRTOS port is also available as an example for the core + peripheral utilization. The opencores project CPU lecture [ 56 ] written in VHDL by Dr. Jürgen Sauermann explains in detail how to design a complete AVR-based system on a chip (SoC).
