E4Coder - facts
is a toolset available since 2012 which is able to:
• simulate continuous time and discrete time designs
• simulate finite state machines
• GUI panel generation
• generate code without changing the design
• with and without RTOS
• Bare Metal / ERIKA Enterprise / Linux / RTAI / Windows
• support for multi-rate designs

E4Coder success stories
example of success stories using E4Coder:
• HVAC Boiler display application
• 54 states (including 2 AND and 17 OR superstates)
• 9 levels deep
• 8 bit microcontroller
• 6184 bytes of flash, 547 bytes of RAM.

E4Coder success stories
Velometro used E4Coder for the VeloCar control model
• both in simulation and code generation
• same diagram for different target boards
• press release available
… but… what is a VeloCar?

E4Coder GUI - customizable UI designer
E4Code GUI is a simple customizable UI designer:
• design simple user interfaces
• insert simple widgets
• simulate the interface
• generate QT target code
Ports
Edit area
Properties Widgets

E4Box
E4Box is a ready to use all-in-one embedded computing box
• Intel Atom processor
• NI PCI-6221 Data acquisition board
• Open Edition
• Linux+RTAI+Comedi+open source code generator
• Professional Edition
• Open Edition + E4Coder

dashboard demo
the Dashboard example is available as one of the default
E4Coder demos.
the demo includes:
• two state machines that control gear change logic
• an E4CoderGUI simulation panel that shows an animated
motorbike dashboard.
The demo mimics the Matlab/Simulink/Stateflow demo named
“Modeling an Automatic Transmission Controller”
