About Sample Source: TNeo - a well-formed and carefully tested preemptive real-time kernel for 16- and 32-bits MCUs

TNeo is a compact and fast preemptive real-time kernel (RTOS) for embedded 16/32-bit microprocessors. It supports priority-based preemptive scheduling and round-robin scheduling for tasks of equal priority. Originally a thorough re-implementation of TNKernel v2.7, TNeo features well-formed code, extensive unit tests, comprehensive documentation (HTML/PDF), and support for ARM Cortex-M (M0/M0+/M1/M3/M4/M4F) with multiple toolchains (GCC, Keil, clang, IAR) and Microchip PIC32/PIC24/dsPIC.
