Installere Driver (CP2104)

På nogle computer skal der ikke bruges en driver da Windows selv finder ud af det. men med en CP2104 USB chip skal computer i nogle tilfælde have en driver den kan downloades her.

Download: CP2104 Driver

Programmering

Før du kan starte din programmering skal Arduino’s IDE software hentes. Dette program bruges til at programmere chippen.

Download fra dette link: Downlaod

Inden programmeringen kan udfæres skal den rigtige “COM” port findes. Klik “Værktøj/Port” – og vælg COM port.

Installere ESP package (Arduino IDE)

 

Installere TinyGSM-0.11.5 Library

  • Download library (Download)
  • Udpak filer
  • Flyt/kopir mappen “TinyGSM-0.11.5” til  “libraries” som findes i “Arduino IDE” mappen (C:Program Files (x86)Arduinolibraries)
  • Åben Arduino IDE software og klik på “Sketch/Include library”
  • Klik nu på “Add Zip. library” og find Zip filen du lige har downloaded.
  • Åben “Sketch/Include library/Manage Librarys” for at opdatere library.
  • Luk, og åben Arduino IDE programmet. (Genstart programmet)
  • Nu er “TinyGSM-0.11.5” installeret

Installere OneWire-2.3.7 Library

  • Download library (Download)
  • Udpak filer
  • Flyt/kopir mappen “OneWire-2.3.7” til  “libraries” som findes i “Arduino IDE” mappen (C:Program Files (x86)Arduinolibraries)
  • Åben Arduino IDE software og klik på “Sketch/Include library”
  • Klik nu på “Add Zip. library” og find Zip filen du lige har downloaded.
  • Åben “Sketch/Include library/Manage Librarys” for at opdatere library.
  • Luk, og åben Arduino IDE programmet. (Genstart programmet)
  • Nu er “OneWire-2.3.7” installeret

Eksempel

Her viser vi et hurtig eksempel på hvordan du får modulet til at sende en besked når D2 indgang aktiveres.

Info: Modulet kan godt sende en SMS kun ved USB tilslutningen til computeren.

Status LED:
Der er 2 LED’er på boarded. Den ene skal lyse konstant (Ved knappen) den anden er “Network” den blinker hurtigt hvis der ingen forbindelse er (Gøre den i ca 1 minut efter opstart) hvor den efter skal blinke langsomere.

Du skal bruge:

Forbind sådan:

  • GND (Modul) – Push Button
  • 2 (GIOP2 Modul) – Push Button

Info: Modulet kan godt sende en SMS kun ved USB tilslutningen til computeren.
