    Re: MQ 135 sensor

    As far as I know, best way in PBP is to use lookup table and linear interpolation.

    Re: Nextion Touchscreen LCD User Interface

    Now you get me interested in this display...
    I installed editor, and I got very nice surprise. You can use PIC with simulator/debugger.
    Second, I think that this code

    AdcVal VAR BYTE
    AdcVal_A...
  4. Re: with the pic16f628a off, a voltage on an1 comes out from main voltage pin, why?

    Why you don't connect A1 after switch?

    I have FP library running on few 18F46K80 and 18F87j50.
  7. Re: AD8302 Phase and magnitude to complex impedance

    First, I now see that I have mistake in formula, all items with "i" should be on right. I used online calc to solve it. Looks like that I need to solve by hand...
    Answer to your question is yes, and...

  9. Re: AD8302 Phase and magnitude to complex impedance

    Step 6: Realize how stupid you are, and how some things are simple :)
    Math is actually fairly simple.
    M=Vf/Vr-magnitude signal from AD8302. p- Phase from AD8302, Z0-system impedance

  10. Re: AD8302 Phase and magnitude to complex impedance

    That is usually case. But I want it to be in real working condition(bolted to wall) or on other surface.
    So trimming isn't problem.
    Step 1: Make longer antenna,
    Step 2: Just go to antenna clip...
  11. Re: AD8302 Phase and magnitude to complex impedance

    I need to design custom shape of antenna. Antenna is in plastic box, partially potted, low height etc. In short antenna is in place where no antenna should be.
    I already used noise source+bridge+RTL...

    I want to create something like this:

    From last video I'm missing Im and denominator.

  13. Re: AD8302 Phase and magnitude to complex impedance

    Pic and registers etc doesn't mater at all... I do not have problem with code, I have problem with math..
    Complex impedance is just way of representing magnitude and phase. It looks like Z=R+jX,...
  14. AD8302 Phase and magnitude to complex impedance

    Hi,
    I didn't know where to put topic, so if it is wrong place...

    I have project where I need to match 868MHz antenna to 50R. So I build sort of antenna analyzer.
    I used this bridge...
  15. Re: Low power accurate 6 month timer - suggestions?

    Thanks for info. I'm wondering how much devices will be recovered...
    Also please report your experience with microcrystal RTC. I have one dev board on shelf, but newer tried...
  16. Re: Low power accurate 6 month timer - suggestions?

    How you will get data from bottom of sea?
  17. Re: Low power accurate 6 month timer - suggestions?

    If you need low power, accurate, and small part I'll go with microcrystal RTC.
    3.2x1.5x0.8mm, 40 nA @ 3 V, 1 ppm @ 25C, Fout 32768...to...1Hz, alarm with int pin.
    Need more?
  18. Re: Getting data from user, how to store it properly? (kinda dialog interface)

    48 word array will hold 48 steps...
    Just create array for x,y,z,s...
    Eg

    X VAR WORD[48]
    Y VAR WORD[48]
    Z VAR WORD[48]
    S VAR WORD[48]

    FOR steps=0 to NoOfSteps

    Also measure from GND to GND.
    Schematic would help a lot.

    Re: HTML and PIC communication

    Just to say again to be clear...
    From your modem you need to open this link

    and put variables name and value after ?

    Unfortunately I can't log...

    Re: HTML and PIC communication

    It contains PHP. It isn't pure HTML.
    So script need to be hosted on server.
    You can use free server for testing.
    eg: www.000webhost.com
    This isn't ad, just sharing one that worked for me.
