#84826 - blanking a false external interrupt |
I want to stop a false external interrupt signal triggering an isr on timer0 for about 2.5mS. What is the best way to do this.
Should i configure timer1 to run for 2.5mS with GATE=0 and ET0=0 then after 2.5ms in the isr for timer1 -> reset the IE0 incase a flag has been raised, set GATE = 1, IT0=1 (falling edge), EX0=1 (enable int) and enable timer0 ET0=1 (interrupt). Then when the signal i want is received this will trigger the isr of timer0 after the 2.5mS. Will this work??? or is there another way?? |
