No, it is correct.
However you have to decide what do you want. Thread have to be
started by ISR or it should run perodically in a "self-propelled" way.
A tipical periodic task looks like this:
thread_code()
{
pthread_make_periodic_np(pthread_self(), start_time, period);
for(;;) {
do_something();
pthread_wait_np(); // I wait for next period
}
// never reached
}
A tipical interrupt driven task is like this:
thread_code()
{
for(;;) {
pthread_suspend_np(); // ISR wakes me up by pthread_kill()
// or pthread_wakeup_np()
do_something();
}
}
