  1. Re: Determining variable length (number of digits) possible?

    You are mixing string with numeric values...

    12345 is a decimal number.

    LEN or any other similar command (LEFT, RIGHT, MID) will take as an input just string characters, not numeric values.

  2. Re: 12F683 GPIO.3 MCLR pin - unusual response

    GP3 does not have any other function except MCLR if set to.

    So the erratic behavior may be related to the software. Show the code please.

  3. Re: Replacing array member on the fly (big LCD characters idea)

    Indeed, it looks very nice! Nice work.

  4. Re: Replacing array member on the fly (big LCD characters idea)

    OK, depends on what you want to do. If you want to place the LCD opposite of the sun, yes, nextion will not fit in.

    In anyway, most of the user interface is well covered with these displays. As...
  5. Re: Replacing array member on the fly (big LCD characters idea)

    And there is Nextion displays, in many sizes, low cost, with touch and colors to do anything like that with almost zero overhead in programming.

    But in either case, nice study case.

  6. Re: Replacing array member on the fly (big LCD characters idea)

    Nice and clear fonts. Good work!

  7. Re: Replacing array member on the fly (big LCD characters idea)

    On the custom character, unless explicitly stated, you should consider it full of rubbish.

    Re: Better code check before compile?

    Interesting... This is easy to check I guess.

    Re: TM1638 LED Display Driver/Controller

    Thank you for the nice contribution and detailed comments on the code.

  10. Re: Replacing array member on the fly (big LCD characters idea)

    then combine accordingly like that:



    a_left=(byte_var & %11111000)>>3


    to make it right justified if needed.

    Ioannis
  11. Re: Replacing array member on the fly (big LCD characters idea)

    Something like this?



    byte_var var byte
    a_left var byte
    b_left var byte

    byte_var=%10101010
    a_left=byte_var & %11111000
  12. Re: PIC16F15355 config setting to work on internal OSC with clock 4MHz

    I do not have this chip but maybe you should do also this:

    OSCCON1=%00000011
    OSCCON2=%00000011

    So you will have a 32MHz/8=4MHz

    You also have the FCMEN_ON which means that if your main...
  13. Re: Can we have multiple 1-wire devices on single pin?

    The idea is to have the PIC as a master device and the PIC to request a communication.

    So, with the available commands, it is not possible to make a PIC react as a slave 1-wire device.

    You have...
  14. Re: Replacing array member on the fly (big LCD characters idea)

    Really nice job on the big numbers.

    What is the difference between parallel - serial LCD? Other than electrical connections and some specific commands? Have not used serial so far but I guess...

    Re: Any elegant way of text string handling?

    Why not use a termination character, say 0 terminated string.

    So you only have to check if you reached the 0 value in the data area that your message is stored.

    This is what Richard suggested....

    Re: Better code check before compile?

    It is common to other languages too like C for example.

  19. Re: Converting PULSIN reading to RPM, from PC Fan?

    Yeap! That's right! Nice picture with the two grands! Well I hope I don't look that old though...

  20. Re: Converting PULSIN reading to RPM, from PC Fan?

    I was thinking in terms of frequency and the low frequency you stated pushed me into that error. Sorry...

    Thanks for the clarification.

  21. Re: Converting PULSIN reading to RPM, from PC Fan?

    Maybe you mean x2 instead of divide by 2.

    Ioannis
  22. Re: Converting PULSIN reading to RPM, from PC Fan?

    In your case you need an input.

    Can you multiplex with another CCP input?

  23. Re: Converting PULSIN reading to RPM, from PC Fan?

    There is this Tip n Tricks pdf that has #5 about RPM measurment using CCP in combination with #1 and #2 tips.
