1. Embedded Operating System Jason Porter

2. What is Embedded From Wikipedia: “An embedded system is a computer system with a dedicated function within a larger mechanical or electrical system, often with real-time computing constraints.”

3. Examples Arduino Raspberry Pi PLC Automotive Computers

4. Arduino Vs TinyOS TinyOS is a full fledged operating system TinyOS and APIs are designed for low power applications Arduino focuses on I/O TinyOS focuses on wireless networking

5. Hardware MicaZIRIS

6. Hardware (cont.) NXTMOTETelsoB

7. Software Stack Split-phase APIs nesC

8. Stack One Stack Singular Longer Life Span

9. Split-phase First phase: Start Second phase: Callback

10. APIs Rigorously tested All split-phase Bidirectional

11. nesC Dialect of C Explicitly define interfaces Bidirectional Requires two files Configuration Module

12. nesC - Configuration Defines interfaces Used Provided Is used to generate executed

13. nesC - Module Lists interfaces Provides implementation Major Operation APIs

14. Conclusion TinyOS is used for Wireless embedded projects Has APIs Non-blocking Bidirectional
