No Sandy, look:
Blinky is not the starting point for EVERY application.
Why don't you start to build programs from scratch?
Build you own LED blinky in a different way. Using the systick-timer, or the MRT, or.....
Start becoming mentally flexible.
Modification of exisiting programs is a loser approach.
You keep on trying with the LPC800 which is a good thing, but you need to start walking on your own feet.
Create functions you can rely on. Simple ones. LED initialization. LED on. LED of. (You've already done?? No! You can't even do that at the moment. Because all you do is copy-and-past and modify a number, possibly!)
With the simple functions you can move on to more complex tasks, like printing text. Debugging with the simple functions. Start with printing a char. Then strings. Then buffer contents + length. NOT printf() at the first step.
Use simple peripherals in the beginning. SCT is NOT. MRT is. NVIC is. GPIO is. SystickTimer I'm not sure. SWM is NOT. ROM-API is NOT. Pin-Interrupts/Pattern matching is NOT. UART is NOT. Use the simple peripherals and simple programs (coded by YOU) to learn programming.
EDIT: forgot U(S)ART
