prva vec, ktora sa mi nepaci je ten delay v loope - ono to zasekne aj stranku.
lepsie je pouzit
Kód: Vybrať všetko
time_t t=now(); //nastav t= aktualny datum cas
void loop() {
server.handleClient();
if ((t+5)<now()) { //ak t+5 sekund <aktualny - teda preslo viac ako 5 sec.
t=now(); //aktualizuj premennu
cidlo.read(dht11pin);
teplota = cidlo.temperature;
Serial.print(teplota); //odmeraj, vypis teplotu
}
delay(10);
}
takto mozes riesit pocas tych 5 sekund aj ine veci (napr. obsluhovat web server) a nebude program blokovany cakanim. a meranie bude kazdych 5 sec
samotny vypis bud urobis replace %teplota% na aktualnu hodnotu, alebo ako to robim ja:
Kód: Vybrať všetko
void setup() {
server.on("/", handleGenericWeb);
server.on("/config", handleConfigWeb);
server.on("/api", handleApiWeb);
server.begin();
}
void handleConfigWeb() {
String webPage ="<!DOCTYPE html><html><head>";
webPage+=" <style>";
webPage+=" body {}";
webPage+=" table { border-collapse: collapse; border: 1px solid black; }";
webPage+=" input { border: 0px; border-bottom: 1px solid black; }";
webPage+=" th { background-color: black; color: white; }";
webPage+=" td { padding: 3px; border: 0px; }";
webPage+=" .r { text-align: right; }";
webPage+=" .btn { width: 100%; height: 30px; background-color: red; color: white; font-weight: bold; border: 0px;}";
webPage+=" </style>";
webPage+=" <meta charset='utf-8' /><title>Main Config</title></head>";
webPage+=" <body><form action='' method='post'><table>";
webPage+=" <tr><th colspan='2'>Global Settings</th></tr>";
webPage+=" <tr><td class='r'>SSID</td><td><input type='text' maxlength='20' name='fssid' value='"+(String)fssid+"'></td></tr>";
webPage+=" <tr><td>Password</td><td><input type='password' maxlength='20' name='fpassword' value=''></td></tr>";
webPage+=" <tr><td colspan='2'><input class='btn' type='submit' name='fsavedata' value='Save Config'></td></tr>";
webPage+=" </table></form></body></html>";
if (server.hasArg("fsavedata")) {
server.arg("fssid");
server.arg("fpassword");
server.send(200, “text/html”, webPageSaved);
} else {
server.send(200, “text/html”, webPage);
}
}
skladam stranku priamo s hodnotou
fssid: to je moja premenna s nazvom wifi siete
fpassword: heslo na wifi
fsavedata: - tlacidlo, ktore hovori, ze chce ulozit zmeny
ak fsavedata nie je prazdne - server.arg(...) tak viem, ze dal odoslat data. hodnoty z webu su v tych premennych server.arg("fssid")
ja to mam tak, ze to spracujem a zobrazim stranku s textom ulozene a automatickym presmerovanim na uvod (webPageSaved).
