  1. Re: Question regarding Interrupt handler - No DT_Ints used.

    Thanks for your input tumbleweed. What you said coincides with what I have been able to gather by looking at the LST file. As Richard pointed out, I may have been stepping on system variables but...

    Thanks for all your help Richard.
  4. Re: Question regarding Interrupt handler - No DT_Ints used.

    I tried to show it in code quotes but it was too long. Please look at the attached file.
  5. Re: Question regarding Interrupt handler - No DT_Ints used.

    I like it too! There is just not enough room to use it. Thanks all the same.
  6. Re: Question regarding Interrupt handler - No DT_Ints used.

    Thanks for the pointer Richard.

    I have looked through the entire LIST file not sure what I was looking for.
    I looked at the following variable/ram locations and there were no inconsistencies...

    Richard,

    So doing it this way as well " is a recipe for failure"? Please see example below.

  10. Question regarding Interrupt handler - No DT_Ints used.

    Hello everyone.

    I'm just wondering if I should be concerned when using an inline assembly interrupt handler to save w, status and pclath, then using pbp code to something, then reverting back to...

    Re: PIC18F67K40 DT_INTS that really work.

    Dave,

    I have never used a "DEFINE USE_LOW/HIGHPRIORITY 1" for any of the interrupts I have used at work or for personal projects while using DT_INTs.
    I just set the bits accordingly as shown...

    Re: PIC18F67K40 DT_INTS that really work.

    If you mean code examples, this is what I am currently working with as of now, mind you I'm running this PIC at 64Mhz.

    I haven't gotten to the 3rd high priority interrupt, which is next on my...

    After experimenting for a few days, I cannot get any timer interrupt to work. I even went as far as using assembly interrupts that I wrote while not using the DT_INTs-18. Nothing seems to want to...

    PIC18F67K40 Timer issues

    Hello everyone.
    I'm currently working with a Pic18f67k40. The issue I'm having is that the timers (1 or 2) don't seem to work. I've modified DT_INTS-18 to work with this pic but my timers still...

    For anyone interested in Richard's code example and how it works, watch the video below.
    The video shows most of what the code does. Thanks for sharing Richard.

    Yes now it does and I now see what you meant by scalable. Range is 000.00 to 599.99
    So at startup with no button push, the knob does nothing until the user is ready to use it.

  23. Re: Rotary Encoder on 20x4 LCD with pushbutton digit select and other features

    If your using 18F chips then that may be the reason why. Perhaps the commands are getting compiled differently for 18F's than for 16F's??
    No matter, I have an 18F4423 I can use to test that...

    I caught that earlier and made the changes then but it still didn't work. Here is my schematic:
    Hope its not too big. If too small, I provided an image attachment.
