hi i whant define function "UART0_IRQHandler" in my library ( uart library ) but i dont whant use #include <lpc17xx.h> and startup_LPC17xx.s
I tried this code but did not work void (*test) (void) = (void (*) (void)) 0x54;
in file "LPC176x/5x User manual ( UM10360 )" and "Table 50" :
Interrupt_ID : 5 Exception_Number : 21 Vector_Offset : 0x54 Function : UART0 Flag(s) : Rx Line Status (RLS) Transmit Holding Register Empty (THRE) Rx Data Available (RDA) Character Time-out Indicator (CTI) End of Auto-Baud (ABEO) Auto-Baud Time-Out (ABTO)
dif register for uart :

wtf - sry - see this link ( dif register for uart ) - paste.debian.net/.../
pls help me - i need define interrupt function in my project but i dont whant use this file : "startup_LPC17xx.s"
========== i define all register and clock setting and i removed "startup_LPC17xx.c" but i cant define interrupt function in my project
no person cant help me?
Until you understand what startup_LPC17xx.s does, you will not be able to add its functionality somewhere else and add your own interrupt handler routines.
fortunately, if you do use startup_LPC17xx.s, you can just write a c function with the same name as in startup_LPC17xx.s and the Default handler will be replaced with your function.
In main (or somewhere)
void UART0_HandlerIRQ(void) { your code here }
Will cause your UART0_HandlerIRQ{) function to be called every time it is activated.
You really do need to understand what startup_LPC17xx.s does before you can remove it. it is only about 250 lines. It would be helpful if you did not post again until you understand what startup_LPC17xx.s does and how you plan on making sure startup happens properly without using startup_LPC17xx.s
The instructions for posting source code are simple, and clearly stated.
See: www.danlhenry.com/.../keil_code.png
That's no reason not to look at what they (and others) have done, and learn from it.
If you want to build from first principles, then you'll need some good references:
http://infocenter.arm.com/
http://www.keil.com/books/armbooks.asp
In particular, I would recommend Joseph Yiu's Definitive Guide series.
