  1. Re: My DT_Interrupts broke in PBP3... guess I'm too dense too figure out why

    Hi Darrel,

    Thanks for your help. I'm sorry I haven't followed through with this yet.

    I discovered wet carpet in a spare bedroom and traced it back to a leak in the bathroom.

  2. Re: My DT_Interrupts broke in PBP3... guess I'm too dense too figure out why

    I'm sorry Darrel, I'm getting to where I can't even cut & paste the right code anymore.
    I think I need to step away from the keyboard and go make some cookies or something instead.

    THIS gives the...

    Thanks Darrel!
    I knew I'd done something stupid and that was it!

    Welll... part of it.
    It did indeed get rid of those errors, but it brought up some fresh ones.

  4. My DT_Interrupts broke in PBP3... guess I'm too dense too figure out why

    Well, now that I've switched from PBP2..6 to PBP3 I seem to be having trouble with DT_Interrupts in some "previously working" code. :(

    I've read the manual about migrating from PBP2.6 to 3.0, and...

    Re: shifting in decimals

    Sounds rather painful.





    How about modulus? (remainder)

    Re: Power factor measurement

    Ahhhh... do we have a Microchip engineer lurking in our midst? :)

    Greetings Brett!

    AN220 looks like a good read. Thanks!
    (Hmmm... I think I've seen your name on other Microcips AN's as well)

    Re: Watching for pin High

    Have you set the pins to be inputs using TRISA?

    (Heckler's post #5)

    Unless those pins are set as inputs, all other effort will be wasted...

    We're not necessarily misinformed... we just have a lot of old stock to burn up still. :p

    Re: Soldering station

    Here, I'm familiar with the MAX6675 so I'll give you a start...

    This should read the MAX6675 and display degrees C & degrees F on a LCD display.

    Re: PIC18s and Oscillator settings

    I'm not familiar with the 18F4515, but this line looks odd to me...


    @ CONFIG OSC = INTIO67 ;config for internal osc

    Re: Temprature conversion --- C to F

    NORM!
    This works great!
    I tested it with my circuit and it works perfect down to at least -20C (-4F) which is as cold as my freezer goes. :)
    So that should cover the full range of temperature now....

    Thank You Heckler!

    That looks like exactly what I need!
    I should have known that Darrel had already written something cool to cover it. (Thank You Darrel !!)

    I'll have a read through that...

    Temprature conversion --- C to F

    I have a temperature sensor (MCP9800) that spits out a 12 bit - 2's compliment number that represents degrees C from - 55 C to + 125 C.

    I think instead of having 31 consecutive memory locations that contain a "1", I'd just store the first 1 and arrange my code so that when it looks up those locations they all point to the one slot...

    Nope, that didn't work.
    OK, 8 bit math then....

    Thanks!
  20. Re: Better location for articles and projects.

    Yes please! I'd like to 2nd those thoughts.
    The wiki area is terribly depressing to wade through only to find most of it is empty.
    An index of the articles somewhere "up front" would be great.

    OK, curiosity got me so I tried it with WORD values and it still seems to work...


    x = 32768
    Y = 32769
    x = x + y
    Result: X = 1, STATUS.0 = 1

    Wow... thanks Darrel. THAT is an interesting item to know about.
    I'm sure I can make good use of that!

    Ioannis, I'm using a 16F887. And thanks for helping explain the STATUS thing!
