    Closed: Re: Nextion hex to Nextion LCD

    .
    I understand that you have 16x2 lcd now.
    You want to replace it with nextion touch type.
    For that you must rewrite your original display routine for the touch type and in the nextion format.

    you must give still more detailed description of the requirement.

    -what is 'convert transfer a hex file'?
    -is the hex file is for nextion?
    -a push button input to be transferred to touch screen?

  9. Closed: Re: Reducing 10K lineat potentiometer to 1K, what about lineatity then?

    the nonlinearity is valid .there may be variation in the point at which the rate changes.


    your circuit has 47k log pot.
    but trying to replace it with 10k linear pot and 1k resistor?

    phase voltage is line voltage in delta connection.
  11. Closed: Re: Reducing 10K lineat potentiometer to 1K, what about lineatity then?

    it will be non linear.
    upto 10% of the initial travel , the resistance rate changes(between the wiper and common) will be low.
    beyond that it will be more upto the top end.

    [PIC]Closed: Re: lcd interfacing with pic 16f877a

    your lcd_init() function should have the 4bit interface and the number of lines in the display related code plus other mode set codes.

    otherwise lcd will not display the characters.

    again a typo.

    the term 'c' is left out in denominator.

    so the freq is of the form:

    frequency of your circuit is:

    1/((R2+k*Rv1)+(1-k)*Rv1)

    where 'k' as per figure is 0.41
