Hi,<br><br>thanks for your reply. <br><br>the reason of the need for delay is that :<br>i want to add some milliseconds delay between contiguous hardware configuration instruction. <br>so maybe it's no need to use this powerful method such as timer.
<br>so are there any alternative way to achieve this goal?<br>p.s. where are those examples use timer server i can refer to?<br> ( i want to learn how to use timer too )<br><br><br><br>another questions for register irq handler:
<br>if i want to use function_A as irq #B's handler<br><br> thread_ref_t thrd;<br> thrd = thread_create_simple( function_A, NULL, 100 );<br> hardware_register_interrupt( thread_l4tid(thrd), B );<br>
<br>is the right way to register it?<br><br><br><br><br><div><span class="gmail_quote">2007/11/29, Jorge Torres <<a href="mailto:jorge.torres.maldonado@gmail.com" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">

<div>Hi,</div><div> </div><div>You can use iguana's timer server, there are some examples, at which you can look at,</div><div> </div><div>Cheers,</div><div> </div><div>Jorge<br><br></div><div class="gmail_quote"><div>

<div><span>Hi,<br><br>i wonder know if OKL4 or Iguana has any system call or API that can delay<br><br>several msec,( similar to uDelay or mDelay in linux kernel). and how to use it? <br><br>ex: which header file i should include, and what function i can call?
<br><br><br>another quetion is about request IRQ:<br><br>in linux kernel there is a functin named request_irq whitch can map a IRQ# to a handler routine. <br><br>i noticed there is a function named hardware_register_interrupt in iguana, but the parameters are
<br><br>IRQ# and a thread id. it doesn't make sense for me. why not a handler routine instead of a thread id?<br><br>if i want to rigster a handler routine for a IRQ#, how should i do?<br><br></span></div>_______________________________________________
