    Re: PIC18F67K40 DT_INTS that really work.

    Dave,

    Ok so I did the experiment but I used two identical timers with identical settings and I ran them both using the same format I've been using and also using the format described in you post...

    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...

    Re: PIC18F67K40 Timer issues

    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...

    Re: PIC18F67K40 Timer issues

    Hello tumbleweed.

    Thanks for posting the additional lines of code. Unfortunately, it didn't help. I also searched for version 3.4c but was not able to find it. I managed to find version 3.4b...

    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.

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

    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.
    Push Button, user...
  13. 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...
  14. Re: Rotary Encoder on 20x4 LCD with pushbutton digit select and other features

    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.

    For anyone interested, here is a video of my code, even though its long, but working with the hardware setup as in Richard's comment. Changed my code to reflect that. I think it would help me if we...

    Thanks Richard for commenting and posting code. Your code takes up much less space. I made the hardware changes to my setup and included the necessary configuration registers for programming. I...

    Thanks Ioannis, after all, it was your idea that started this little venture.
  18. Re: Rotary Encoder on 20x4 LCD with pushbutton digit select and other features

    The previous post was an attempt to write code for a rotary encoder that would allow the user to increment or decrement the value displayed by a factor of 1, on a 20x4 LCD. The range was set for...

    Re: OLED 128X96 cheap china lcd

    Hi everyone,

    After looking at your schematic, the only problem I see is if the pull-up resistors are tied to +5v, then you would probably be damaging the inputs to the display. They are at 3-3.3v...
