Beta versions will end with an odd number in the hundredths Minor code clean-up: All references to PCintPort::curr are now explicit. (EDITORIAL NOTE: If you want to really learn something, teach it!) I corrected it so the code now operates in the proper order. Will start over again from memory location 0- just as if you'd pressed the reset button. At that point the value of the pointer is 0, so this means that the Arduino Interrupts and actually creating a valid link to an interrupt handler, it is possible to get an Thus in the small interval between turning on the Interrupts for the given pin, and the code that enables Pin Change Interrupts, ahead of actually From the Release Notes:Ĭode reordering: Starting in version 1.3 of this library, I put the code that enables Version 1.71beta is now available for upload. h file actually contains the code, any variable or function definitions would occur twice and cause compilation errors- unless #ifdef'ed out. This is necessary because the IDE compiles both your sketch and the. When #include'd by another library you should #define the LIBCALL_PINCHANGEINT macro. The library has been modified so it can be used in other libraries, such as my AdaEncoder library ( ). Now the (interrupt-less and) relatively fast operation of filling a circular buffer is used in the interrupt routines. The zipfile comes complete with the ByteBuffer library see the ByteBuffer/ByteBuffer.h file for a list of changes, and see the PinChangeIntTest sketch for a usage scenario. So I have taken SigurðurOrn's excellent ByteBuffer library and modified it for my own nefarious purposes. Hopefully this will help avoid the embarrassing bugs that I have heretofore missed.Īs well, it has come to this author's (GreyGnome) attention that the Serial class in Arduino 1.0 uses an interrupt that, if you attempt to print from an interrupt (which is what I was doing in my tests) can easily lock up the Arduino.
