External interupts

[dz2869]

Trying to convert a V8 project to V9.
PIC18F45K40
I am using External Interrupts INTR0 and INTR1 on B0 and B1
They work fine in V8 but do not seem to be working in V9

Attached is a small project that demonstrates the problem.
The program should toggle between the numbers 1 and 9 on the display.
Seems that INT0 always triggers INT1 so the number 9 is always displayed.

Thanks for any help on this one.

Anyone had a chance to look at this one yet?

Thanks

Hello,

I've compared the C code produced by v8 and v9 for your project file and the C code appears to be identical.

I would be interested to know if your v9 is using the latest PIC compiler or if using the same PIC compiler as v8. You can check this by going into View -> Global Settings -> Locations tab and looking at the Override toolchain locations for PIC.

The v8 compiler will look something like this.
C:\Program Files (x86)\Flowcode\Common\Compilers\pic\

whereas the v9 PIC compiler will look something like this.
C:\Program Files (x86)\Flowcode\Common\Compilers\picv2\

If we can narrow it down to a compiler issue then it makes it easier to try and find the solution.

Ben,

I actually haven't tied running the compiled V9 code on actual hardware yet.
I stopped after seeing that the program did not simulate correctly inside the flowcode application.
Maybe its just a simulation issue.

I'll check on the compliers

Thanks,
Dave

Hi

Interrupts does not simulate in any version of Flowcode ,even in your V8 the code will not simulate maybe it worked in Hardware

Hello,

Pin based interrupts should work fine. That helps me narrow down where I'm looking. I'll have another look for you now.

Edit. Found and fixed the problem and posted the fix to the update system. Thanks for letting us know.

Working now
