Hello,
This is my first post on this forum, I would appreciate any help you could give.
I have a class that points one of a union of pointers at a variable from the program and updates it during an interrupt service routine. I have to use the pointer because the ISR can take no arguments and I do not know until run-time which variable will be attached. I am using a union because I don’t know until run-time which type the variable will be.
The code attached to this post works. It works great for what I want on Arduino. But when I put the header and program in separate files and make a library, it still compiles, but the variable doesn’t get updated. I have done some debugging and I know the ISR is being fired. For some reason the pointer is not being dereferenced to my variable. But again, if I copy out all the parts from .h and .cpp files and put them back into the sketch, things work fine.
I’m sure I’m missing an #include in this header or something.
