I am preparing to tackle my first project using interrupts and have been looking at Darrel's Instant Interrupts. The link I have is for DT_INST-18 Ver 3.3 but the web page says this is for use with PIC18F's. I intend to use a PIC12F683 or PIC12F1822 for my project. Am I correct in assuming that DT_INST-18 cannot be used on these devices? If so, is there another version which can be used?
