Block diagram editor and real time code generator for Python

pysimCoder

pysimCoder is a Rapid Prototyping application, that can be used to generate realtime code for different targets.

At present it is possible to generate code for Linux (with or without preempt-rt) on PC and Raspberry PI, for the BRIKI card (partially on the SAMD21 uC, see www.meteca.org) and for the NuttX RTOS.

The behaviour is similar to other RPC applications like Simulink and XCos.

Despite the fact that the main purpose of pysimCoder is to generate RT control code, it is also possible to perfom simple simulations mixing continous time and discrete time blocks.

Since 07.09.2022 pysimCoder implements subsystems (more than one block, right mouse click) and a new save format, based on json, which replaces the previous format of the files based on XML. Old files can be loaded and saved in the new format. The new format is better readable, because it can be simply opened by a python script like this:

import json
import pprint

fname = 'example.dgm'

f = open(fname,'r')
msg = f.read()
f.close()
fileDict = json.loads(msg)
pprint.pprint(fileDict)

A Virtual Machine (Virtual Box) is available. Please write to me to get the address and password to download it.

It is also possible to get a docker image with pysimCoder using

docker pull robertobucher/pysimcoder

Launch application

pysimCoder

pysimCoder as docker image

It is now possible to use a docker container and image to run pysimCoder:

Install docker (see https://docs.docker.com/engine/install/ubuntu/).

Download a pysimCoder image directly from the Docker Container page:

docker pull robertobucher/pysimcoder:latest

or

docker pull robertobucher/pysimcoder:novnc

The first image can be launched with

$ docker run --rm --env="DISPLAY" --net=host -v $XAUTHORITY:/tmp/.XAuthority -e XAUTHORITY=/tmp/.XAuthority robertobucher/pysimcoder:latest

At the prompt launch

psc

The second image (pysimcoder:novnc) runs from a web browser:

$ docker run --rm -it -p 8080:8080 robertobucher/pysimcoder:novnc

Open a browser and go to http://<server>:8080/vnc.html

In the terminal launch

psc
