Hi,

I am trying to generate time delays but had no success with pt_wait.

I think pt_wait use is not straight like pt_wait(env, CONDITION).

Here is the test code. Wha tam I doing wrong? Thank you.

#define SYS_FREQ (80000000)

typedef struct timer_s {
    long start;
    long interval;
} timer_t;

typedef struct {
    pt_thread_t pt_thread;
    pt_func_t   pt_func;
    timer_t     tmr;
} thread_context_t;

BOOL timer_expired(timer_t *t) {
    return (ReadCoreTimer() - t->start >= t->interval);
}

void timer_set(timer_t *t, long msec) {
    t->interval = (SYS_FREQ / 2000) * msec;
    t->start = ReadCoreTimer();
}

static pt_t
thread(void *env) {
    thread_context_t *c = env;

    pt_resume(c);
    pt_yield(c);
    timer_set(&(c->tmr), 3);
    while(!timer_expired(&(c->tmr))) pt_yield(c); // better use pt_wait?
    pt_yield(c);
    return PT_DONE;
}
