SCL pins should be different, SDA can be shared on one pin. Note that historically many NodeMCU drivers and modules assumed that only a single I²C bus with id 0 is available, so it is always safer to start with id 0 as first bus in your code. If your device driver functions do not have I²C bus id as an input parameter and/or not built with Lua OOP principles then most probably device will be. NodeMCU; NodeMCU Default I2C & SPI pins; I2C. I2C can be used to connect up to 127 nodes via a bus that only requires two data wires, known as SDA and SCL. SDA=4 => D2. SCL=5 => D1 ; SPI. SPI is much simpler than I2C.

Arduino 16×2 I2C LCD, Nodemcu 16×2 i2c LCD Code & Library- I have been using 16×2 LCD in different projects. For displaying the Date and time information, In a password-protected door security system, and so on. A regular 16×2 LCD module needs a lot of wires, due to which maximum of the controller I/O pins are wasted NodeMCU has I2C functionality support on its GPIO pins. Due to internal functionality on ESP-12E, we cannot use all its GPIOs for I2C functionality. So, do tests before using any GPIO for I2C applications. Example. Let's write Arduino sketch for NodeMCU as I2C master device and Arduino sketch for Arduino Uno as I2C slave device. Master device sends hello string to slave device and slave. Neben vielen Anwendungen, bei denen hauptsächlich Daten erfasst werden, ist der ESP8266 auch zum Anzeigen von Daten geeignet.

NodeMCU ESP8266: Details and Pinout: Today, we will talk about ESP8266 pinning, or in other words, NodeMCU. Personally, I really like this component, as it already comes with USB input. But it is important to explain that the NodeMCU is formed by an ESP12E, which still has an ESP8266.. The PCF8574 I/O expander is powered with 3.3V that comes from the NodeMCU board (PCF8574 VDD pin is connected to NodeMCU 3V3 pin and VSS is connected to GND). SDA and SCL pins of the PCF8574 are respectively connected to NodeMCU pins D1 and D2. A0, A1 and A2 pins of the PCF8574 are address select pins, they decide the I2C address of the chip. NodeMCU ESP12 Dev Kit V1.0 Pin Definition: Image Source: Google Image Search (image is used for quick reference and non-profit purpose only) While writing GPIO code on NodeMCU, you can't address them with actual GPIO Pin Numbers. There are different I/O Index numbers assigned to each GPIO Pin which is used for GPIO Pin addressing. Refer following table to check I/O Index of NodeMCU GPIO Pins. ESP8266 I2C Core. ESP8266 hardware supports only one i2c. But in bit-banking(Bar Metal code) method you can use all your gpio pin as i2c pins.

ESP8266 and ESP32 I2C LCD Interface. ESP8266 (NodeMCU) I2C LCD Interface Parts Required. I2C LCD Display Module PCF8574; 16×2 LCD Display; Connection Wire GND is a ground pin of ESP8266 NodeMCU development board. I2C Pins are used to hook up all sorts of I2C sensors and peripherals in your project. Both I2C Master and I2C Slave are supported. I2C interface functionality can be realized programmatically, and the clock frequency is 100 kHz at a maximum Was mache ich falsch oder wo liegt der Fehler. Ich verwende eine Nodemcu 12E mit einem BMP 180 dran. Ich habe schon ein Projekt laufen mit einen DHT22 Sensor das läuft absolut einwandfrei. Auf dem Bord wurde ein Kernel mit I2C, DHT22, Onwire, Http, u. a. Modulen geflasht. Insgesamt sind 18 Module auf dem Bord für meine zukünftigen Projekte. Natürlich kannst du das Board auch jederzeit vorher aufwecken indem Du selbst Reset am NodeMCU Board drückst (also Pin RESET kurz auf GND legst). Achte darauf das Du beim testen des DeepSleep eventuell das USB Kabel abziehst, manchmal kann der den Reset Pin blockieren. Auch darf der Reset oder GPIO16 PIN natürlich nicht irgendwie fest auf einen Pegel gezogen werden. Wenn das alles nicht.

I2C. The ESP32 has two I2C channels and any pin can be set as SDA or SCL. When using the ESP32 with the Arduino IDE, the default I2C pins are: GPIO 21 (SDA) GPIO 22 (SCL) If you want to use other pins, when using the wire library, you just need to call: Wire.begin(SDA, SCL) The data connection is I2C (I²C, IIC or Inter-Integrated Circuit) and this interface is also called TWI (Two Wire Interface). The on-board pins can be in different order, so always triple check before hooking it up to your project. Operation voltage is between 3v to 5v but, it is best to use the guidance from the manufacturer's datasheet I2C. I2C can be used to connect up to 127 nodes via a bus that only requires two data wires, known as SDA and SCL. SDA => D2. SCL => D1; SPI. SPI is much simpler than I2C. Master and slave are linked by three data wires, usually called MISO, (Master in, Slave out), MOSI (Master out, Slave in) and M-CLK. M-CLK => D5; MISO => D6; MOSI => D7 (SPI Bus SS (CS)is D8.)

ESP8266 Wi-Fi Microcontroller for compatible (NodeMCU V2), Pinout: 11 GPIO pins, 1 ADC, 3V3, GND OLED Display (128 x 64) with 4pin I2C connector DHT11 Sensor with 3 pin boar On NodeMCU, the defaults are D1 and D2, since SDA = 4, and SCL = 5 - but 4 and 5 are actual GPIO numbers, not digital pin numbers. Ask Espressif why. As you can see above, Sparkfun decided to use 2 and 14 for I2C GND pin goes to NodeMCU GND, VDD pin can be connected to 3.3V or 5V, SCK is the clock pin on OLED Display which is connected to D5 of NodeMCU for SPI clock. The SDA pin which is MOSI pin on OLED of SPI interface goes to D7 of NodeMCU. The RESET pin goes to D3. DC, the data command pin is connected to D2 of NodeMCU. The last pin is CS goes to D8, chip select of NodeMCU

Hey there, I use a nodeMCU as ESP8266 gateway and wanted to add a few sensors to it to avoid using a sensor node right next to the gateway. I first tried with a temp sensor Si7021. But how to connect it to? Vin and GND is. Here is the pinout of the Geekcreit ESP12F DEVKIT V3 as far as I can make it out. GPIO3 and GPIO1, labelled RX and TX above, are accessed as D9 and D10 in the NodeMCU 1.0 (ESP-12) board definition of the ESP8266 Arduino library. There is no nice name for GPIO10 (SD3) gpio-pin drei ist (zumindest auf dem nodeMCU-board V1.0) mit dem Flash-Taster verbunden. Das heißt wenn man direkt nach dem Anschließen der Spannungsversorgung (durch USB-Kabel bzw. nach einem Druck auf den Reset-Taster, den Flash-Taster heruntergedrückt hält, wird das Skript init.lua ohne Aufruf des Skriptes MyLuaCode.lua beendet
