Thread Creation Backend#

A backend for pw::Thread is offered using k_thread_create(). This backend only supports threads with static contexts (which are passed via Options). All created threads support joining and detaching. To enable this backend, add CONFIG_PIGWEED_THREAD=y to the Zephyr project`s configuration.

#include "pw_thread/detached_thread.h"
#include "pw_thread_zephyr/config.h"
#include "pw_thread_zephyr/context.h"
#include "pw_thread_zephyr/options.h"

constexpr int kFooPriority =
    pw::thread::zephyr::config::kDefaultPriority;
constexpr size_t kFooStackSizeBytes = 512;

pw::thread::zephyr::StaticContextWithStack<kFooStackSizeBytes>
    example_thread_context;
void StartExampleThread() {
  pw::thread::DetachedThread(
      pw::thread::zephyr::Options(example_thread_context)
          .set_priority(kFooPriority),
      example_thread_function, example_arg);
}

Thread Sleep Backend#

A backend for pw::thread::sleep_for() and pw::thread::sleep_until(). To enable this backend, add CONFIG_PIGWEED_THREAD_SLEEP=y to the Zephyr project`s configuration.
