Designing a Simple Real-Time Operating System from Scratch
Real Time OS Article
Log Entry 1: Defining Core Objectives and Hardware Abstraction The initial phase involved establishing a clear set of requirements to prevent scope creep. I decided that this RTOS would target a single-core ARM Cortex-M class microcontroller (like the STM32F4 series) due to its prevalent use in real-time embedded systems. The primary objectives were to implement
