PIC16F1825 IOC Interrupt

[DirkB]

Hello,

the ioc interrupts on the pic16f1825 doesn't works.
I need ioc Interrupts on 5 Pins on port a. Two of the
interrupts must be trigger on both edge. Is this possible?

thanks

Dirk

Hi Dirk,
Have you selected the pins and how you would like them triggered?

If so, are you saying they just don't work?
Do you have either internal weak pull-up, external pull-up or pull-down resistors?
If not I/P's could be floating.

Hi Martin,

i have external pull-ups on A0 and A1 for trigger both Edge
using reflex-coupler, pull-downs on A3, A4 and A5 for trigger
with switches on rising egde. Setup is right. A0, A1 green, A3,
A4 and A5 red ;o)
For testing A0 triggers a macro only a LED goes on in a loop.
No interrupt works. ???

Hi
How do you see if the controller is running? do you have a LED that is flashing at a fix rate for example

Can you post your flowchart so we can see if we can spot something?

Hello at all,

I have probably found a bug. If you activate several interrupts,
only the last one of the activated interrupts will work. The others
will be deactivated.
Think it is a Job for Ben ;o)

Hi Dirk,

This shouldn't be the case, please can you attach a simple program that exhibits this problem and I will investigate for you.

Edit, I see you've created a new topic with an attachment so I've answered here.
