Good morning all,
I am trying to develop Stepper Program, based on English Charlies [you tube clip](https://www.youtube.com/watch?v=9zgymotxRe8&t=471s)
Attached is my version
[Pan Stepper to Arduino.xodball](https://forum.xod.io/uploads/short-url/j4ylp7U21IgbSalnaZFjGcm5Pyc.xodball) (327.9 KB)
I have a C++ error for Fatal error Wire.h which comes up nearly straight away after selecting Simulate, see below.
Other information I have is:
\*Simulate does not colour the node red to identify the incorrect node
\*The Debugger starts but does not finish
\*I get a red circle with a line through next to Deployment
_Does anyone know how to fix this?_
Thanks in advance
David

The generated C++ code contains errors. It can be due to a bad node implementation
or if your board is not compatible with XOD runtime code. The original compiler error
message is above. Fix C++ errors to continue. If you believe it is a bug, report the
problem to XOD developers.

Hi David,
Unfortunately it is not possible to simulate hardware devices. See:
> [@Simulation error - please help](https://forum.xod.io/t/simulation-error-please-help/3911/4):
>
> You can’t simulate extra hardware like buttons, LCD, LED, or sensors. These need replaced with tweak or watch nodes or run on actual hardware. You can use debug when running on hardware to combine tweak/watch nodes with extra hardware.
