how to use wiggle with keil arm?

The problem is that there is a timing delay between the instructions that talk to the interface and the data actually going in or out the parallel port
I believe that some of that, in addition to hardware changes, is courtesy of Mr. Gates. When Windows abandoned the DOS base, the I/O became "real enough time" (which for many things in not "real enough") instead of real time.

The same apply to the RTOSs that really should be name URTOS, since the "real enough" "philosophy" apply there as well.

It is sad when some developer somewhere decide what is real enough for you.

my best thanks to Alexey Selishev ,Ward Jon and erik malund ! thanks you give more good advise.I think many beginer's need is a sample wiggle link with pc's parallel port.
so a sample and chip wiggle and a dll can used in keil ........I think Keil's AGDI is a good solution.but i'll find it until it appear in the internet!:))

now I use IAR EARM 4.11 and a sample wiggle to debug my program.but i think keil and a dll can use wiggle is the best choice

anybody can help me ????God to sale ulink to get more money !!!

"God to sale ulink to get more money !!!"

Do you mean you need to sell your uLink?

If so, How about eBay?
