  1. Closed: Re: Microcontroller pin not working after some time.

    The current driving the 7-segments display sounds comfortably dimensioned, so it is unlikely that there was a burning problem, except of course due to improper handling when energized; frankly, I...
  2. Closed: Re: framing specifications for a control problem

    Each set of specifications determines one or more methods to solve the problem that can be done by graphic and/or algebraic approaches. There is no "simple example" given such a broad question.
  3. Closed: Re: Electromagnetic interferences - how to handle?

    Without knowing exactly what the circuit is, it is difficult to make a more accurate guess, it may be for example that you have not connected anywhere a high impedance input, having a floating static...
  4. Closed: Re: Component values on 2-pole 2-zero compensation

    For practical purposes, the transfer function of this circuit is simplified to the op amp inverter topology, so the gain would be defined as ((1/sC2 + R2) // C1) divided by ((1/sC3 + R3) // R1). ...
  5. Closed: Re: Freq computation without DIV instruction for 8bit MCU

    Your requirements are restrictive; you could consider setting timer scaler to a interval between acquisitions as a rational number power of two, so that division could be replaced by a simple right...
  6. Closed: Re: Components nomenclature on PCB silkscreen

    Whenever there are repetitions of circuits in the project, it is preferable to encapsulate them in a block, repeating it as many times as necessary, prefer automation of the component designator...

    Do you see it as a COM device ?

    It is likely you don`t have the driver installed.

  9. Closed: Re: How the washing machine Automatic Load Sense works?

    If you had the curiosity to search on the Web for the terms "washing machine auto sensing" would find that it is related the way as water is filled into drum, assuring that all the pieces will be wet...
  10. Closed: Re: How can we send multiple bytes via UART?

    Seems like your are trying to cascade bytes in a dynamic structure such as overloading parameters, which is a resource not available in C language, but rather in C++. Is it the case?
  11. Closed: Re: How the washing machine Automatic Load Sense works?

    Review reply #7: Wet clothes are much heavier than dry, so the weight of dry clothes is negligible in the laundry process. Again: Water absorbing capacity is perhaps the most relevant factor in this...
  12. Closed: Re: How the washing machine Automatic Load Sense works?

    Do you really think there exists any kind of sensor capable to detect the fabric material? In addition, are you assuming that people will always put clothes made with the same fabric at each washing...

  14. Closed: Re: How the washing machine Automatic Load Sense works?

    These washing machines do not sense 'cloth load'; there are pressure sensors which detects the water level, and this somehow suffice for a rought estimate. As said, many of these equipment have...
  15. Closed: Re: How the washing machine Automatic Load Sense works?

    From the above, seems like you are considering "cloth load" as the mere insertion within the washing machine drum; you migh know that dry clothes are significantly lighter if compared to wet, which...
  16. Closed: Re: Simple C code for 50 point moving average filter using Buffer

    Another useful concept you'll need to know during code implementation is the circular buffer, which can be used to add/remove samples, one per time, keeping the last 49 ones.

    Closed: Re: Writing one file into another in C++

    No, I never used the ofstream method, and have no idea how this works.
    BTW, why not starting with a even simplest approach, such as suggested on #11?

    Closed: Re: Writing one file into another in C++

    I did not spent much time to find a possible solution, few minutes actually, searching for tips on the Web, and added the constraint you have defined, exactly as Brian suggested above at post #4.

    Instead of asking for something that does exactly what you want, why don't you look for an example that makes the exact copy, and then seeks into the code for the part that scan each byte and then...

    This is the bit mappings of the data/control pins, necessary to configurate and or opperate the LCD; there is no much to 'understand' there, just set these pins acording timmings and order defined at...

    Closed: Re: Ferrite bead usage in ADC's

    This kind of filter only would make sense if it were made with a common mode choke, but both component designators FB1,2 are clearly for distinct (uncoupled) devices. It is likely someone copied the...

    Did you try changing the simulation options from "Default Settings" to either "Settings for better convergence" or "Settings for better accuracy"? It can be done at Menu on System>>Set Simulation...
  25. [SOLVED]Closed: Re: I wrote simple code buttons to rotary for PIC12F509, but it works only on simulat

    As said above, your code have a lot of blocking instructions that blinds the program for a while preventing from reading the actual encoder, for which we should just guess it have a resolution of...
