NodeMcu Lua WIFI Internet Things development board based ESP8266 CP2102 module<\/a><\/p>\n\n\n\n

G\u0142\u00f3wne cechy NodeMcu ESP8266 v2:<\/strong><\/p>\n\n\n\n

  1. Napi\u0119cie zasilania 3,3V (logika)<\/li>
  2. Standard 802.11 b\/g\/n<\/li>
  3. 10 GPIO – ka\u017cdy mo\u017ce dzia\u0142a\u0107 jako I2C, PWM, 1-Wire<\/li>
  4. Cz\u0119stotliwo\u015b\u0107: 2.4GHz<\/li>
  5. Komunikacja USB CP2102<\/li>
  6. Programowanie w LUA, ARDUINO, AT<\/li>
  7. Wymiary modu\u0142u: 26mm x 48mm<\/li><\/ol>\n\n\n\n

    \u017beby Arduino IDE zobaczy\u0142o urz\u0105dzenie, trzeba \u015bci\u0105gn\u0105\u0107 CP210x USB to UART Bridge VCP Driver<\/a><\/em> i oczywi\u015bcie zainstalowa\u0107.<\/p>\n\n\n\n

    Po po\u0142\u0105czeniu kablem micro USB komputera (hub-a) i p\u0142ytki mo\u017cemy otworzy\u0107 okno Terminal-a i wstuka\u0107 nast\u0119puj\u0105c\u0105 komend\u0119: 
    ls -al \/dev\/cu*<\/code>
    Nazwa nowego urz\u0105dzenia kt\u00f3ra si\u0119 pojawi to cu.SLAB_USBtoUART<\/strong>.<\/p>\n\n\n\n

    UWAGA! Zdarza si\u0119, \u017ce nowego urz\u0105dzenia nie ma na li\u015bcie, a wszystko zrobili\u015bmy jak nale\u017cy. U mnie w maku tak by\u0142o i sp\u0119dzi\u0142em kilka dni na szukaniu b\u0142\u0119du. Znalaz\u0142em. By\u0142 nim \u017ale dzia\u0142aj\u0105cy hub usb2. Gdy pod\u0142\u0105czy\u0142em kabel USB do gniazda w komputerze (usb3) mac odzyska\u0142 wzrok. Czasem trzeba wyj\u0105\u0107 i w\u0142o\u017cy\u0107 ponownie wtyczk\u0119 USB do gniazda komputerowego. Tak mia\u0142em przy \u0142adowaniu programu do ESP8266 przez Arduino IDE. Po\u0142\u0105czenie USB to czu\u0142y punkt. Najwa\u017cniejsze – nie poddawa\u0107 si\u0119!<\/em><\/p>\n\n\n\n

    ESP8266 i Arduino IDE<\/h2>\n\n\n\n

    Mo\u017cliwe jest programowanie naszej p\u0142ytki przez Arduino IDE. Trzeba w tym celu wykona\u0107 kilka czynno\u015bci.<\/p>\n\n\n\n
