Hi, i seem cant get this code merge together... maybe in the loop or in setup?

Parola_Scrolling_ESP8266 + Parola_Display

how to change this code

sprintf(curMessage, "%03d:%03d:%03d:%03d", WiFi.localIP()[0], WiFi.localIP()[1], WiFi.localIP()[2], WiFi.localIP()[3]);

to this ?

sprintf(pc[curText], PA_CENTER, SPEED_TIME, PAUSE_TIME, effect[inFX], effect[outFX]);

currently im using this code & it work to display the text but would not updated to curMessage from the web form.

P.displayText(pc[curText], PA_CENTER, SPEED_TIME, PAUSE_TIME, effect[inFX], effect[outFX]);

or maybe need to change from curText to curMessage in this loop ?

` if (P.displayAnimate()) // animates and returns true when an animation is completed { // Set the display for the next string. curText = (curText + 1) % ARRAY_SIZE(pc); P.setTextBuffer(pc[curText]);

// When we have gone back to the first string, set a new exit effect
// and when we have done all those set a new entry effect.
if (curText == 0)
{
  outFX = (outFX + 1) % ARRAY_SIZE(effect);
  if (outFX == 0)
  {
    inFX = (inFX + 1) % ARRAY_SIZE(effect);
    if (inFX == 0)
      P.setInvert(!P.getInvert());
  }

  P.setTextEffect(effect[inFX], effect[outFX]);
}
if (newMessageAvailable)
{
  strcpy(curMessage, newMessage);
  newMessageAvailable = false;
}
P.displayReset();

}`

well i need the button reset in the HTML too.

thanks
