Embedded Operating System Jason Porter

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.”

Examples Arduino Raspberry Pi PLC Automotive Computers

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

Hardware MicaZIRIS

Hardware (cont.) NXTMOTETelsoB

Software Stack Split-phase APIs nesC

Stack One Stack Singular Longer Life Span

Split-phase First phase: Start Second phase: Callback

APIs Rigorously tested All split-phase Bidirectional

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

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

nesC - Module Lists interfaces Provides implementation Major Operation APIs

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