Pi Webserver to Arduino

Good thanks, I know it's LAMP, but is P for PHP or Python in your case?

Are you programming in PHP or Python, or other?

Only using html at the moment. The code is over here: viewtopic.php?f=4&t=6648

I've just used the sketch example for the 8 channel relay shield.

You are painting a very confusing picture here...

The link you provide has Arduino code not HTML, but more so if you are talking running two computing like devices such as a Pi and an Arduino you are talking TWO different sets of programming languages.

a. Arduino typically via Arduino IDE a Java like language.

b. Raspberry Pi typically when running LAMP (Linux, Apache, MySQL and a P language) is running PHP^^, but could be Perl or Python.

https://en.wikipedia.org/wiki/LAMP_(software_bundle)

Hence my question, although I did forget Perl!

So I need to know for your Raspberry Pi LAMP setup is it Perl, PHP, or Python?

If you don't know then it leaves this thread cold.

BTW...

What state/city are you in?

Do you visit any other forums for assistance on these matters?

^^ This forum site uses PHP, hence phpBB.

Sorry, I meant this part of the sketch was html

Code: Select all

    /* store the HTML in program memory using the P macro */
    P(message) = 
      "<html><head><title>16 Channel Test</title>"
      "<body style='background-color:powderblue;'>"
      "<form action='/control' method='POST'>"
      "<h1 style='color:red;font-family:comic sans ms;font-size:200%;text-align:center;'>16 Channel Test</h1><hr>"
      "<div style='float:left;width:60%;'>"

My Raspberry Pi is using php.

I'm in the Newcastle area and no I haven't posted this on any other forums as yet. I've been trying to research a lot of this myself. As it is I've hit a bit of a hurdle with implementing a momentary switch in the mix but that's another problem lol

I hope I am not getting confused myself, as either you are still confused, or how you are writing this is confusing.

A Sketch implies Arduino, not Pi LAMP, so what the heck is the HTML doing on the Arduino?

A typical Arduino does not have a User Interface like a Pi does, but of course there are exceptions.

Are you telling me your Arduino Sketch is an exception in some way?

The typical case use is Arduino as device controller, interfacing with a Pi for human interaction.

Do you have some exception to this case use I am not aware of?

All I've done is use the example that Jon has shown in this video from SuperHouse https://www.youtube.com/watch?v=jvuvyiyVqtc

Only modified the html a little bit to make it look nicer.

keiranwyllie · Post by **keiranwyllie** » Tue Aug 23, 2016 7:13 am

All good, I've moved the webpage across to my Pi and added the following to the html:

Code: Select all

<form action="http://10.0.0.100/control" target="dummyframe" method="POST">

<iframe width="0" height="0" border="0" name="dummyframe" id="dummyframe"></iframe>

This works great now.

DaveMark · Post by **DaveMark** » Tue Aug 23, 2016 7:46 am

None of this makes sense.

Me thinks you are leaving out some aspects.

keiranwyllie · Post by **keiranwyllie** » Tue Aug 23, 2016 9:06 am

I don't think it's that difficult to understand, it should be pretty simple (pic attached). I added the lines above to my html on my Pi (the HTML that was formally running on the arduino as its own webserver) and it's working.

Code: Select all

<html><head><title>16 Channel Test</title>
  <body style="background-color:powderblue;">
    <form action="http://10.0.0.100/control" target="dummyframe" method="POST">

No sorry, that's still just too simplistic, it still doesn't add up.

I should just clarify that I have over 30+ years of computer experience, including Web technologies, and furthermore I also check with a highly experienced friend, and we both agree that something is being left out of this equation.

That video link you gave before does not provide direct access to ANY source code/files to assist us.
