hello all, i have one arm7 kit of lpc2148. and one IDE is provided with it, its name is SCARM, i have written one simple program of led on-off in SCARM and downloaded it and it is working fine. When i wrote the same program in keil, and i included its header file and startup file. compilation is successful.but when i downloaded the file in same board it is not responding. i want to solve this problem. is it because of startup file or something else? and i want to use keil as SCARM code size is restricted to only 2Kbyte. pls help me thank you
The problem may not be the startup file - it may be "something else".
You have given absolutely no details whatsoever about the startup file that you've used, and absolutely no details whatsoever about the rest of your application - so how on earth do you expect anyone to be able to say what might be wrong, or where?!
It's like saying, "my car won't work; what's wrong with it?" - when we don't even know what car you have!
But, if your code looks like this www.spjsystems.com/scarm.htm then it's highly likely to be an Optimisation issue - search the forum about using software delay loops in High-Level Languages (HLLs)...
