Hello all, I am working on a personal project - an RTOS for a XC167. It is fun and all goes well (still need to cut off some time of a context switch duration though - currently around 118 micro) and I am hoping to write one more system call to allow a task to wait for an interrupt to occur. I was going to allow this type of call: rtos_interrupt_wait(int32u interrupt) which puts a task in a seperate queue (out of the ready list) until the interrupt occurs. but in order to catch an intercept, you must always compile your code with a function that declares itself as an ISR, not? that implies that I should write some kind of macro to catches an interrupt, and copy-paste it with different interrupt numbers to handle all possibilities. but is there a better, more code efficient way? I failed to program my interrupt vector table (at least when its beginning was located at memory 0x0). Thanks in advance, Tamir
hi, thank for your reply! I am going to make my system call a macro that expands the right ISR. the expanded code will then orginize everything with the kernel. I haven't tried it yet, but that seems much easier than rewritting the interrupt vector table...I have two simple questions though (out of curiosity): can I modify the contents of the interrupt vector table while the program is running? my instinct says NO... do you know where I can find the source of Monitor166? thanks again, Tamir
