Webpage Text to I2C 1602 LCD using SPIFFS.....

By GengusKahn
- Tue Nov 03, 2015 5:04 am #32918 This is a version of the WEB Text to LCD using the SPIFFS to filter via String manipulation very simply.....There are more efficient way's but this is so simple to use for not only the LCD but increase the field size and interact with the "Running Sketch"......

This is the base snippets to allow incorporating into any sketch All declarations need to be made previously e.g. Strings......

If the Webpage files are KEPT below 2KB then there is no need to chop them up to send, just save the file in 2KB chunks...index1.htm, index2.htm etc.....then send each file consecutively......
Using lots of SPIFFS but virtually no memory or sketch space.....

The LCD is driven via Level shifters on GPIO 4 and 5, using the Standard Arduino Libraries and the ESP8266 Latest release, I have not included any of this to allow this to be used on even the -01 with limited I/O.....


The Webpage action....
Code: Select all// /ajax_inputs&L1=123456789&L2=&nocache=968337.7823963541 This is the returned data  "123456789" on line 1 "" line 2
   if (sPath.startsWith("/ajax_inputs&L1="))  // get request.....
   {
     tmtxt1="";
     tmtxt2="";
    got_text = true;                    // print the received text to the LCD if found
File temptext = SPIFFS.open("/temp.txt", "w");     
  if (temptext) {
    temptext.print(sPath);
    temptext.close();
    delay(1);
      }
    else {
      lcd.clear();
      lcd.print("rOr Temp.TXT");
      delay(10000);
    }
    File in = SPIFFS.open("/temp.txt", "r");
     in.setTimeout(0);
       Dtmtxt = in.readStringUntil('=');
       tmtxt1 += in.readStringUntil('&');
       Dtmtxt = in.readStringUntil('=');
       tmtxt2 += in.readStringUntil('&');
     in.close();
       tmtxt1.replace("%20", " ");
       tmtxt2.replace("%20", " ");
        lcd.clear();
        lcd.setCursor(0, 0);
        lcd.print(tmtxt1);
        lcd.setCursor(0, 1);
        lcd.print(tmtxt2);
      delay(3000);
   }


The LCD Webpage loader.....
Code: Select all if (sPath.startsWith("/lcd"))
  {
                           // send rest of HTTP header
                        client.println("HTTP/1.1 200 OK");     
                        client.println("Content-Type: text/html");
                        client.println("Connection: keep-alive");
                        client.println();
                        // send web page
                      File webFile = SPIFFS.open("/index1.htm", "r");        // open web page file
                        if (webFile) {
                            while(webFile.available()) {
                                client.print(webFile.readString()); // send web page to client
                            }
                            webFile.close();
                        }
  }


Finally the Webpage....Place this in the SPIFFS using FS Tool, name this index1.htm
Code: Select all<!DOCTYPE html>
<html lang="en">
    <head>
        <meta charset="utf-8">
        <title>Environment Monitor Text to LCD</title>
        <script>

        strLine1 = "";

        function SendText()
        {
            nocache = "&nocache=" + Math.random() * 1000000;
            var request = new XMLHttpRequest();
           
            strLine1 = "&L1=" + document.getElementById("txt_form").line1LCD.value;
            strLine2 = "&L2=" + document.getElementById("txt_form").line2LCD.value;
           
            request.open("GET", "ajax_inputs" + strLine1 + strLine2 + nocache, true);
            request.send(null);

Re: Webpage Text to I2C 1602 LCD using SPIFFS.....

By varind
- Mon Sep 12, 2016 2:28 pm #54974 I have created a project that takes specific parts of a webpage and posts them to an LCD. The project lets you easily define what to search for, layout on the LCD, and even supports a large font size. I hope you find it useful.
