    Re: HTML and PIC communication

    Here is an interesting html tag:

    <meta http-equiv="Refresh" Content="3">

    that forces the browser to reload the page every 3 seconds.

    Makes the variables update kind of automated.

    Re: HTML and PIC communication

    No code available. The MCU it had was something like NXP LPC series.

    Re: HTML and PIC communication

    Once I had a device (GSM remote controller) that was communicating to the PC via a RS-232 cable. On the PC side there was a small bridge program that opened the RS232 and a page in a browser.

    Then...

    Agreed Ricahrd.

    But right now the physical layer is not my main concern. There are many options either wired or wireless (though I prefer wire for many reasons and all my devices are static IP,...

    Re: HTML and PIC communication

    I really hoped could get away with just html for now. Besides there are not much needed on such a project.

    Just receive and send some data, mostly numeric to set parameters on the PIC side and...

    Re: HTML and PIC communication

    Thanks for the replies. The phy layer is not difficult and either with cable or wireless will be OK. Even better a GSM modem (which is my final goal) as pedja089 pointed.

    My concern is on the html...

    HTML and PIC communication

    I am trying to understand how can a PIC communicate to an HTML page for displaying and receive data.

    Say that on the HTML page there is a text box to enter a value and a button to send this value...

    Crazy! Well done Richard. You must be very patient person. That one I guess needed endless hours to finish.

    The @ INC _yourvariable may be even smaller in regard to code size.

    Re: Stable Adc Reading Routine

    That code gets 16 samples not 10. You just have to limit the samples from 16 to 5. But this is not very useful. Leave it as it is for ironing out the noise or parasites in the signal.

    Re: ADC input signal filter selection

    I prefer the inductor on the +Vdd side.

    Anyway, I'd suggest get 10 or more samples in an array, then sort them in order and keep the middle 5 values.

    Then add them together and divide by 5.

  13. Re: Motor Control Circuit (JPG Attached) for scrutiny and discussion...

    At 5V I doubt the relay has 15mA current to set it ON.

    Do use a transistor to drive it.

  14. Re: Need to drive 40 pins on variable change, is there a way to do it in elegant way?

    Oh yes. I was carried away by the VOLT<1 or >1 and concluded you were checking for 1 volt and not 1 LSB.

    Sorry about that.

  15. Re: Need to drive 40 pins on variable change, is there a way to do it in elegant way?

    This may oscillate around the set 180 volts about 36 volts!

    If I am not wrong, 180 to 5 needs a /36 divider. +/-1volt of control * 36= 36 volts.

    This may be a problem...

  16. Re: Need to drive 40 pins on variable change, is there a way to do it in elegant way?

    What is the actual DC output voltage?

    This code is far away from output regulation anyway.

    It is his 3rd post that is irrelevant to the thread or on new thread.

    Under supervision. Either playing or testing?

    It is inside your PBP folder. And sure in your Start menu if you type in the search box Picbasic it will show up as PICBASIC PRO Reference Manual.pdf

    Richard was clear. IOC are available only for PortB<4:7> for this chip. So you have to connect your buttons on these lines for IOC.
