I know how to make a fiq in CARM,but asfor the real View,it seem different. Can somebody help? Should I write the program like this: __irq void FIQ_Handler (void) { IOSET1 = 0x00FF0000; //Set the LED pins EXTINT = 0x00000002; }
but I see the startup "FIQ_Handler B FIQ_Handler" it seem like a endless loop,how can I make the code jump to FIQ
Try replacing
FIQ_Handler B FIQ_Handler
with your own C code FIQ_Handler
IMPORT FIQ_Handler ;FIQ_Handler B FIQ_Handler
where FIQ_Handler is the name of your FIQ C function. Even better, you can replace the branch to itself with your own fiq code in assembly.
FIQ_Handler ;your assembly here
