Interrupt handling

  • Hi,
    I'm currently developing an application that needs to reed a foot pedal, for which I think the best way would be to use the interrupt handling capability.
    The embedded computer that I'm using is the DX-4 from AndersDX (check this "link":http://www.andersdx.com/products/embedded-displays/hardware/dx4.aspx).
    However, even though I'm following the provided examples (including the installation procedure for the recommended Ubuntu machine) I always end up with a "module.h" and/or a "interrupt.h" "file not found" message.
    I'm using Qt and eldk-3.0.50.
    Any ideas?
    Thanks in advance.

    Without more information, it's pretty much Crystal Ball debugging. However if you are missing header files then you probably didn't configure your project correctly.

  • Hi,
    I've downloaded the last version of eldk, extracted the missing files but it gets even worse... Now is requesting much more files after copying the necessary/missing files.
    Sorry for this but I'm quite new to Qt... :(
    Any idea how to solve this?

  • If you use a qmake project, typically only the Qt directories are in the search path and the ones from the compiler.
    Check the qmake docu for how to add additional include paths.

  • Thanks, i'll give it a go

  • Regarding the interrupt... well... it didn't work, however I've decided to go for a polling method on one of the GPIO pins which so far seems to be working.
    Anyway thanks for everything.
