hello ı need lpc2378(olimex lpc-p2378 dev.board) timer blink sample for
eclipse.
ı tried this code but not worked..
void Initialize(void);
void feed(void);
void IRQ_Routine (void) _attribute_ ((interrupt("IRQ")));
void FIQ_Routine (void) _attribute_ ((interrupt("FIQ")));
void SWI_Routine (void) _attribute_ ((interrupt("SWI")));
void UNDEF_Routine (void) _attribute_ ((interrupt("UNDEF")));
void T0isr (void) ;

void FIQ_Routine (void) {

where is my fault?

Pack the - Complete source-code including startup-code - Linker-script - Makefile (or at least output of the build-process where all options can be seen) into one zip-archive and attach it to a message. You may find this example-application useful: http://www.siwawi.arubi.uni-kl.de/avr_projects/arm_projects/index.html#lpc23xx_demo1
here is my bad sample project... please give me any ideas. thax four your reply. =) Regards.
http://www.siwawi.arubi.uni-kl.de/avr_projects/arm... this link's project occured so much errors on the new project :(
HELLLLLLLLLLLLLLLLLLLLLLPPPPPPPPPPPPPPPPPP...ANY IDEAS?? TSSSSSSSSSSSSSSS :(
If you have still problems, I have modified the project. It seems that you have copied several files from different projects. Please note that in this project the main clock is 72Mhz. I have lowered the blink frequency so that the LED blinking is visible. PS: I am using the Codesourcery toolchain (arm-none-eabi) so you may have to change the Makefile accordingly. The WinARM toolchain (arm-elf) should work as well.
thanks for ur support didnt work on my workspace.it gave error aagain :s ////////////////////////////////////////////////////////////////////// **** Build of configuration Default for project blinkyy **** make all -------- begin (mode: ROM_RUN) -------- arm-elf-gcc (GCC) 4.4.2 Copyright (C) 2009 Free Software Foundation, Inc.

The file `Common/src/Startup.S' seems to be missing. Did you extract the entire archive? I'd recommend you to start without eclipse as the project files are not very portable. Extract the archive to some temporary folder, adjust the toolchain in Makefile and try to call 'make' from within a dos box in that folder. Just tried that myself (extracted blinkyy.zip, with unaltered Makefile). I am using make.exe from the WinAVR project.

thank you so much ;) working so good ... my problem is .. didnt open archive correctly .. ı followed your advice.. otherwise FIO1DIR,FIO1SET must be FIO0DIR and FIO0SET ;) THANKS FOR YOUR SUPPORT REGARDS ISMAIL
Finally some working interrupt example for this LPC....thanks everyone. Kerbo
very good, it's very useful to me, thank you very much! [Mod: unrelated link removed]
