Welcome to Fusinity Ltd
Fusinity offers unique technology to debug and reflash embedded systems running
in situ. This allows embedded developers
to rapidly debug and develop software running in a realistic working environment.
Fusinity's approach combines the power of debugger-level access to data with the
remote communications of automotive calibration tools.
Fusinity's product provides an all-round Windows toolkit for automotive and non-automotive
software development, acting as a calibration tool, debug tool, CAN tool, and diagnostic tool.
It is much lower cost than traditional calibration tools, yet provides more useful
and instant functionality for software developers making frequent builds.
Two versions are available:
EmSnoop is offered by Fusinity Ltd and can be tailored to work with your
Your system just needs some kind of communications bus that offers
at least a memory read operation.
PiSnoop is offered by automotive electronics experts
Pi Innovo ltd (www.pi-innovo.com),
and sold and supported by them.
It provides an ideal partner to OpenECU (TM) (www.openecu.com)
but also works with other automotive systems.
Includes developer source code examples
to help you work with your own protocols and hardware interfaces.
Includes a comprehensive application note on working with OpenECU.
