>>> extremely limited in third-party SDKs like Zephyr So is almost any non-trivial peripheral feature. Autonomous peripheral operation, op-amps, comparators, capture/compare timers… Zephyr tries to provide a common interface like desktop OSes do and this doesn't really work. On desktop having just the least common denominator is often enough. On embedded you choose your platform because you want the uncommon features.
