Dík za odpověď, ale asi jsem to upravil špatně (zatím v tom tápu). Podívej se na to, prosím Tě, až budeš mít čas.

Jo, ty čidla by byly na jedné sběrnici.

Zdravím chlapi, mám prosbu. Zprovoznil jsem ESP8266 s jedním čidlem(ds18b20) na thingspeak. Potřeboval bych k tomu modulu připojit více čidel(např.4).V HW se celkem vyznám, ale SW mi dělá potíže. Dík za radu.
Tady je kód:

K prvnímu dotazu
Chci napr.nahrát přes převodník usb/uart do esp8266-01 program pro blikání diody na GPI00. Spustím IDE/příklady/esp8266/blink a skončí to hláškou z prvního postu.FW mi jde normálně flešovat. Modul mi přes wifi komunikuje(skenování sítě atd.)Používám Esplorer na AT příkazy.
Nebo jsem nějak mimo?

[terje]

Jaký tam máš FW.

[terje]

Chlapi díky. Jestli se chcete podívat na můj kanál, tak uživatel „terje_ard“. Zatím jenom ze dvou čidel.

[terje]

Díky,funguje. Ještě dotaz. Dá se na thingspeak získat nějaká historie dat nebo jen to co je tam aktuálně zobrazeno.

neumím do příspěvku vložit obrázek. už jsem zkoušel všecho možné

[terje]

Díky, zkouším to. Zastaví se mi to na řádku byte Ethernet::buffer[700];
Hlásí to expected initializer before buffer

[terje]

Ahoj ,funguje to perfektně. Díky. Nemohl bys poradit ,jak to rozjet se síťovým modulem (Arduino Mini Ethernet modul – ENC28J60) jsem stáhl, vložil do programu, ale na webu se nezobrazují hodnoty.Hardvéru celkem rozumím, ale programování ne.
