==Settings for the simulink model for code generation==

The following settings must be applied to the simulink model when generating code from it with the realtime workshop & embedded coder. Failure to apply these settings will complicate the subsequent process to integrate this code into the ARM7 runtime platform.
Currently, only single-rate/singletasking models are supported. Other models require a more complex handling of the model_step() function.


===Top level model===

At the top level there must be a simulink model, data exchange with the environment is only possible inports and outports at top level. Code generation from a library is not possible.


===Model preferences===

These settings must be applied in the model “configuration parameters” dialog:
;Solver
:type is “fixed step” (tested with “ode3”)
:fixed-step size is specified, not “auto”
;Hardware implementation
:Device vendor is “ARM Compatible”
:Device type is “ARM 7”

;Real-Time workshop
:System target file is “ert.tlc” (choose the first with no auto configuration)
:Language is “C”
:Optimizations on (faster runs) (may also work without this quite as well)
:Deselect “generate makefile”
:Select “generate code only”

;Interface
:Target function library is “GNU99 (GNU)”
:Enable floating-point numbers
:Disable “GRT compatible call interface”
:Select “single output/update function”
:Interface is “None”

;Templates
:Deselect “Generate an example main program”
