#108728 - multi tasking Responding to: ???'s previous message |
Stanley Lio said:
the IRRC routine may keep waiting (due to some "JNB IR,$").
Stanley You should write your code so that no module will keep waiting holding the processor up till an action is complete. Something like this:
Loop1:
IF task1 flag
do task1
IF task2 Flag
do task2
.
.
.
GOTO Loop1
The IR routine might be critical so you make it on interrupt, make the interrupt as short as possible and make it set flags for the forground program to take the action. No waiting for action is allowed holding the controller up. Mahmood |
