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;
}
