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”
