Write the program on the Ethernut to return the temperature ONCE only in a
HTML page that has a REFRESH tag up the top of it. Then the browser will
request the page every 10 seconds, updating the page with the current
temperature.

  Hi,

  I would like to see temperatue with web and inserted ADC souce code into
  httpd.c sample as below.

  When I clicked sensor cgi part , I could see my result as below

  00111000 0056 00111000 0056 00111000 0056 00111000 0056
  00111000 0056 00111000 0056 00111000 0056 00111000 0056
   00111000 0056...... -> infinite ^_^
  (because of my infinite loop..)

  Anyway it's ok.

  0056*0.4 = 22.4 -> real temperature value.

  Consequently, I would like to see not  infinite these values
  but temperature value only with constant interval(every 10sec).

  For example, Temp:25'c

  What can I do?

  This is an inserted code in httped.c sample

  static int ShowTemper(NUTDEVICE *sostream, REQUEST *req)
  {
      unsigned char ADC_F7;
      int stat = -1;
      outp(0xff, DDRD);
      outp(0x07, ADMUX);

      NutHttpSendHeaderTop(sostream, req, 200, "Ok");
      NutHttpSendHeaderBot(sostream, "text/html", -1);

      NutPrintString_P(sostream, PSTR("<HTML>"
                                   "<HEAD>"
                                   "<TITLE>Show Temper</TITLE>"
                                   "</HEAD>"
                                   "<BODY>"));

  for(;;)
  {
  outp(0xc6, ADCSR);
  ADC_F7 = (inp(ADCL)>>2);
  ADC_F7 = (inp(ADCH)<<6) | ADC_F7;

  outp(ADC_F7, PORTD);
  stat = inp(PIND);
  NutPrintInteger(sostream, stat, 2, 8, FMTFLG_ZERO);
  NutPrintString(sostream, "\r\n");
  NutPrintInteger(sostream, stat, 10, 4, FMTFLG_ZERO);
  NutPrintString(sostream, "\r\n");
  }
  NutPrintString(sostream, "None");
      NutPrintString(sostream, "</BODY>"
                            "</HTML>");
      NutPrintFlush(sostream);

      return 0;
