Frequently asked Questions
What is included in the STACKFORCE software package?
Our Protocol Stack package includes everything you need for integration:
- Precompiled stack library
- Hardware-specific drivers
- Serial interface (UART, SPI, etc.)
- Power management
- Example applications for quick integration
- Documentation
Is the source code open or encrypted? Can we make adjustments ourselves?
The Protocol Stack itself is delivered as object code and cannot be directly modified. The platform interface (including HAL and RF driver integration) is provided as source code. This allows you to:
- Adapt the platform driver to your target hardware
- Configure specific radio settings such as frequencies
- Optimize driver behavior
- Add your own components such as security and timers
For further adjustments to the stack itself, we are happy to support you with specific development services.
Our requirements are not fully covered by this stack. Can STACKFORCE make custom modifications?
Yes, that’s possible. In addition to our standard solutions, we offer customer-specific extensions of our Protocol Stacks. This enables us to implement your specific requirements so that the stack integrates seamlessly into your system environment.
My preferred hardware is not supported. What can I do?
We are happy to check compatibility with your specific hardware. If your hardware meets the minimum requirements for running a Protocol Stack, porting is generally possible. We can discuss the porting effort with you or provide our Platform Porting Guide so you can perform the porting yourself.
Can we test our preferred stack before making a decision?
Yes. You can request a free evaluation license and test the software in your target environment – without obligation and risk-free. More information about the evaluation offer can be found on our website under: Evaluation License.
Does STACKFORCE provide support for product certification? If so, how?
STACKFORCE uses a multi-stage testing process to ensure high software quality. This includes:
- Unit, module, and firmware tests to check the functionality and stability of individual components
- Static code analysis to detect errors and vulnerabilities at an early stage
- Automated system tests on simulated and real hardware
- Regression tests to ensure that existing functions continue to work reliably and that no new errors are introduced.
