Installere ESP package (Arduino IDE)
- Åben Arduino IDE (Download her)
- Klik “Fil/Egenskaber”
- Indtast dette link i feltet “Additionel Board Manager URL’s”
- Link “http://arduino.esp8266.com/stable/package_esp8266com_index.json“
- Klik OK
- Åben “Værktøj/Board/Boards manager” (Lad programmet opdatere)
- Find “ESP8266” og installere
- Klik derefter “Værktøj/Board” og find (NodeMCU 0.9 (ESP-12 Module))
- “Værktøj/Programmer” skal være “AVR ISP”
- Du er nu klar til at sende en kode
Program Upload: (Arduino IDE)
Da dette modul ikke har en USB interface, skal der bruges en “TTL Serial Adapter Module” som sender programmet over i chippen. Du kan købe den her:
GPIO Pinout port introduce:
| NO. | Name | Function | NO. | Name | Function |
| 1 | GND | Power ground | 13 | IO10 | GPIO10 |
| 2 | Relay | Relay drive port , using IO5 drive by default. If need use other I/O drive relay, please remove R14, then use the I/O connected to this relay pin. | 14 | MISO | Slave output master input |
| 3 | IO2 | GPIO2; UART1_TXD | 15 | IO13 | GPIO13; HSPI_MOSI; UART0_CTS |
| 4 | IO4 | GPIO4 | 16 | IO14 | GPIO14; HSPI_CLK |
| 5 | RX | UART0_RXD; GPIO3 | 17 | ADC | A/D Conversion result. Input voltage range 0~1V, ranging from 0 to 1024 |
| 6 | 3V3 | 3.3V power | 18 | 3V3 | 3.3V power |
| 7 | SCLK | CLOCK | 19 | MOSI | Master output Slave input |
| 8 | IO15 | GPIO15; MTDO; HSPICS; UART0_RTS | 20 | IO9 | GPIO9 |
| 9 | IO0 | GPIO0 | 21 | CS0 | chip select |
| 10 | IO5 | GPIO5 | 22 | IO12 | GPIO12; HSPI_MISO |
| 11 | TX | UART0_TXD; GPIO1 | 23 | IO16 | GPIO16 |
| 12 | 5V | 5V power | 24 | GND | Power ground |
Inden koden kan uploades skal IO0 forbindes til GND imens koden uploades.
Relay output:
NC: normally closed end, the relay is short circuited with com before closing and suspended after closing.
COM: public end.
No: normal opened end, the relay is suspended before closing, and it is short circuited with com after closing.
