Hi, I have made some progress with the interrupt project I am working on. The micro-controller is responding to the push button interrupt but seems that it is not able to come out of the interrupt. I know that when a micro-controller responds to an interrupt it disables the interrupt but in my case it does not. The LED, which should glow just once when the button is pushed, turns on and off indefinitely.
Last week Dave told that are a few problems with the ARM GCC compiler which made me think that may be the compiler isn't producing the correct epilogue for the interrupt function. I decided to declare the function attribute as "naked" and write the function prologue and epilogue myself. Should I embed the code in the interrupt handler or should I declare separate functions for prologue and epilogue respectively ? If I can embed the code how can I do that ? Are there any examples in the library that I can follow ? Thanks, Naga.
