Posted on June 04, 2007 at 09:26I have a problem in my application which , I suppose , refers to wrong interrupts initialization.
In my program I have external interrupts , timer A interrupts , SCI ( UART interupts ) and in continuation - SPI interrupts.
I don't exactly know how even to define my problem.
The following scenario keeps repeating itself:
- The program works , the interrupts are executed
- I decide to tak step forward and made some change/ addition in the algorithm
- The program stops wrokin correctly
- I revert the changes i've made , but the program still doesn't work
- After number of random corrections ( usually associated with interrupts ) the program starts working correctly again.
- And from the beginning........
Is there any determine sequence for interrupts service initialization?
Please help , the isuue is very urgent.
I use ST72F321BAR9 micro
I debug using InDART.
:-? :-? :-?
