Hi,
There are two current forum topics where pinchangeint is being used to read incoming rc signals. In both topics, the ops would like to detach pin change interrupts and later reattach them to enter and exit autonomous and RC Modes. I have suggested that this is not the best approach due to the memory leak in detach. As an alternative, would you consider adding an enable function that will set or clear the relevant bit for given pin in the pin change port masks allowing the user to disable pin changes for one more pins and reenable them later without memory leaks.
