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)
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();
}
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.
