Re: How can I pass a value from Arduino C To HTML?

Hello Archibald, Yes - you´re right. One has to use "server.send"!! With server.send_P I got errormessages. Using "server.send" and omitting "PROGMEM[]" did the trick. I don´t have to save memory so I shouldn´t have used it to begin with. There´s one last question: If you look at the code you might ...

Re: How can I pass a value from Arduino C To HTML?

Dear Archibald, Were you seeing "This should show the temperature" in your computer's browser before you made the last edit ? Yes - because I was the one who made that statement - it was meant to be an example but all it did was making a mess :( Sorry!! This time it compiles - but I can´t see a thin...

How can I pass a value from Arduino C To HTML?

Hello everybody, I ´ve built a simple WIFi - thermometer with an esp8266 and a DS18B20 sensor. The software produces a simple webpage that can be viewed with a computer, cell phone and so on. I like that much better than using just the "server.send(200, "text/plain"" command but there´s one catch!! ...

Re: Separate Values from a String

Mystery is solved - this is what the display "really" shows - I reduced the text-size of "temperature" and found out!!
"tft.print(temperature,1);" does the trick - case closed! Thanks and good bye!!!

Re: Separate Values from a String

UPDATE!!!!!

Re: Separate Values from a String

Thanks again for all you did for me - and of course I´ve changed "hpa" to "hPa" :D :D :D
BTW: I do print the integer and float values to the display - the old "substring-code" is commented out!

Code: Select all

//tft.print(weatherdata.substring(0,4));// air pressure
all the best!!!!!!!

Re: Separate Values from a String

Hello Archibald, I implemented your code and it works - of course. My webserver now sends "1017,23.8,28". But there is one strange phenomenon :o Display.JPG The value "humidity" has a strange "frame" now that wasn´t there before. BTW: Excuse me for all those questions and misunderstandings - I´m goo...
