Hi,

I hate to reply on this issue because it's a while since I messed with the
CCS stuff (and PIC for that matter) but I do remember that the simulator
will hang around executing the code fragment which implements the delay. As
the simulator is deliberately slow, it will appear that the code has hung
up in the delay. Try wiggling the mouse while the code is in the delay -
that seemed to speed up the operation if I remember correctly.

To all,

When simulating the code below when stepping through the program, when the
line delay_ms(100); is executed the program jumps to #use
delay(clock=20000000) and it seems to just stay there!  Is this true or is
it just implementing the delay of 10mS (which is goinig to take a hell of a
lot of steps to acieve manually.  Because when I run the program normally
it seems that the program gets stuck on #use delay(clock=20000000).
