I'm pretty new to embedded programming, so please forgive the poorly
written questions...  I need to drive a few LEDs from an application.  I
see that the LED on-board the GW2348-4 board that I have is driven by
the GPIO (or at least I believe it is).  How do I control that LED?  Is
there a way to turn that LED on/off from an application?  FYI: I'm
currently running a 2.6 uClinux kernel.

I read in the manual for the GW2348-4 that there are registers to
control the digital I/O (GPOER, GPOUTR, etc.).  I assume I need to
access these registers.  How would I go about doing that if, in fact, I
need to?

Thanks in advance for your help.
