Why Nil?

* Of course because it is so small that it is almost nil. * I wrote Nil because I wanted to experiment with an idea I had * regarding a minimal RTOS. Basically I wanted to verify how small * could be an RTOS while retaining useful features. * *

Features

* - Free software, GPL3 licensed. Stable releases include a exception clause * to the GPL. * - Designed for realtime applications. * - Easily portable. * - Preemptive scheduling. * - Each thread has its own priority level. * - Offers tasks, time, semaphores, event flags, timeouts. * - Fully static. * - Minimal system requirements: about 700 bytes ROM with all options enabled. * - Almost totally written in C with little ASM code required for ports. * - Compatible with ChibiOS/HAL. * - API compatible with ChibiOS/RT of which, ChibiOS/NIL, is functionally * a subset. * . */
