Hello all,
I would like to apply an interrupt on change in a 12F1840. Does anyone have an example of this?

Hi Hans,

Did you check the interrupt on change sample file?

Kind regards,

Rob

Hi Hans,

I saw indeed that the library supports only port b. It can be fixed with aliases to also support port a but that need some work because the library is quite large.

I tried to see if it compiles when I add aliases for only port a and only 1 pin and that compiles. Attached your program with using only one pin and a draft update of the change. You can at least test if 1 pin works 🙂

Note that this library is just a hack and far from complete! I was thinking of making the change in a different way so that it requires less work.

So if you are patient I can make the change.

Kind regards,

Rob

Hi Hans,

I had a look at the library but with the current set-up I cannot solve it with aliases since PICs can have multiple ports that support interrupt on change and the library only works for one port (B).

I will give it some more thought ....

Kind regards,

Rob

Hi Hans,

It was easier to update your program than changing the library. I think with the current set-up is it not easy to change the library but maybe someone else has a brilliant idea.

Attached your program version that compiles and not using the library. It was not tested, I leave that up to you.

Kind regards,

Rob

Hi Hans,

Good to hear that. I could add it as sample file as a version that does not use a library.

Kind regards,

Rob

Should we remove the interrupt on change library?

This sample shows a good example of how to use interrupt on change without a library:
18f4620_interrupt_on_change_pin_b0.jal

Or does someone want to update the library?

Matt.

Hi Matt,
Please leave it so it is, i use it in older programs.

Hi Matt,

I had a look at the library but with the current - but clever - set-up it is not easy to change by using the same set-up.

Since I updated the sample program of Hans I can add that too as a sample file that does not use the library.

Kind regards,

Rob

We could remove the samples related to the interrupt on change library, and keep the lib where it is or rename it.

Rob, is there a better way to make a library? Ideally we would want one library that works on all devices.

Matt.

Hi Matt,

Maybe indeed a good suggestion to only keep the samples that do not use the library.

I am thinking if there is another way to build the library so let's wait a while before removing samples. 

For now I would just keep it in the upcoming release.

Kind regards,

Rob
