#16590 - RE: Need Correction in my code |
Thankyou both steve and Lance
The interrurt pin (p3.3) is connnected to PCF8574 pin 13 which goes low upon pressing any key also connected to a pullup resistor 4k7. To Steve Yes Sir I have corrected this mistake and renabled the EA and EX1 but it still does not help the int pin (p3.3) is stuck low upon pressing any key TO Lance Sir I know that the ISR cannot wait that long ,that is why it is vectored of to another place(#Int1Isr). Please be kind enough to explain to me the nesting within the interrupt here in this case |
