Interrupts Identification (handling)

Hi,

Just check if corresponding interrupt flags are set ... before clearing them !

that's all !

LOL so simple ! thank you.
-something like:

...
ON INTERRUPT GOTO IntHandler
...
...
IntHandler:
  If PIR1.0=1 then
     PIR1.0=0 'Clear flag
     ..do my thing...
     RESUME
  EndIF

  If INTCON.0=1 then
     INTCON.0=0 'Clear flag
     ..do my thing...
     RESUME
  EndIF

but.. if I have 10 interrupts enabled and the last interrupt checking ('If' statement) was the triggered, will I always have to check the previous 9 each??, sounds like it will.

PD: ENABLE & DISABLE are optional, am I ok?

Why not use Darrels Interrupts?

You see anther way to check which has triggered ???

it's a Pic specifics !!!

heuuuuu, disable before the interrupt stubb !!! or it will be fun ...

Ioannis ( hello ...) is right ... BUT if your device shows ~> 2K prog space min. ( say ~> 100 SRAM Bytes ...). The 12F683 is the minimum size to allow something "usable" ...

Hi Alain. He stated that the device is F628, so it might fit the budget! But on the other hand, On Interrupts, depending on the length of the PBP program might consume RAM too.
