❄ Frost OS

Frost OS is an async multi-task operating system for embedded hardware,
which supports await/async function calling, and TLS(Task Local Storage).

Frost doesn't interrupt the task execution, so it's not a real-time operating system.

It owns an advanced task scheduler that can run two task types:

• one shot: task runs one shot, then deletes itself
• periodic: task runs periodically, with a given period (setInterval)

It also supported a Golang-like "channel" feature which be used to communicate between tasks. (WIP)

❄ Example

This is a simple example of toggling a LED every 1 second in Arduino:

#include <frost/api.h>

void __task_led_toggle() {
  static int led_state = 0;
  digitalWrite(LED_BUILTIN, led_state);
  led_state = !led_state;
}

void setup() {
  
  // frost init
  frost_init();

  // create a periodic task as a 1000ms interval
  frost_task_interval(&__task_led_toggle, 1000, NULL);
}

void loop() {

  // run frost scheduler
  frost_schedule_tasks();
}

❄ Porting Frost

Please port below functions to your platform to make Frost work:

void __frost_log_print(const char* tag, const char* fmt, ...) {
  // Your platform implementation
}

uint64_t __frost_time_tick(uint64_t* tick) {
  // Your platform implementation
}

And markup FROST_PORTED_LOG_PRINT and FROST_PORTED_TIME_TICK before you include the Frost header.
