Real-Time Real Fast ECU Development

neoECU-20: 4xDWCAN, 1xSWCAN, 1xLSFTCAN, 4xLIN

Intrepid Control Systems introduces neoECU 20, a rapid prototyping tool for CAN and LIN ECUs. neoECU 20 can be setup to control and measure automotive signals in minutes. ECU logic is defined in function block modeling scripts, allowing you to arrive at a workable ECU early in design. Now you have the ability to test your ECU models and accurately create simulation environments without C Code.

Applications For neoECU 20

• Try out new algorithms early in the design process.
• Gateway CAN and LIN signals.
• Integrate into ECU load or ECU test boxes to make them intelligent.
• Allow application engineers who are not C programmers to try out new ideas.
• Create custom test instruments.
• Convert CAN or LIN signals to analog and vice versa.
• Simulate a real ECU environment with dozens of low cost nodes.

General Purpose I/O and Expansion

The neoECU 20 has six general purpose I/O lines. Each line can be programmed to a digital input or output of which four can be analog inputs. One digital line can generate a PWM and another can measure a PWM. All of these I/O can be measured or controlled by both the PC host application or the embedded real-time scripting engine. For example, very precise timing measurements can be made using script for I/O to Network message timing applications. The DB9 Connector also include two power pins to power an external device like a trigger pendant, wireless gateway, or graphical display.
