ESP8266 I2C pins

The ESP8266 doens't have hardware I2C pins, but it can be implemented in software. So you can use any GPIOs as I2C. Usually, the following GPIOs are used as I2C pins: GPIO5: SCL; GPIO4: SDA; SPI. The pins used as SPI in the ESP8266 are: GPIO12: MISO; GPIO13: MOSI; GPIO14: SCLK; GPIO15: CS; PWM Pins . ESP8266 allows software PWM in all I/O pins: GPIO0 to GPIO16. PWM signals on ESP8266 have 10. On your Arduino / ESP8266 you will find two GPIOs (SDA and SCL) for the I2C communication. If you are not sure were to find the corresponding pins, see the following pictures or for the complete pinout you can vitis the following articles: ESP8266 pinou

ESP8266 Pinout Reference: Which GPIO pins should you use

  1. Wire - The ESP8266 should work with any I2C sensor you can throw at it - just use the same Wire API calls you're used to. There are a few differences: Pin definition: The ESP2866 doesn't actually have any hardware I2C pins - those labeled on the Thing are the default, but you can actually use any two pins as SDA and SCL. Calling Wire.begin.
  2. Unfortunately my board uses pin D2/GPIO4 (which is a standard Arduino pin for I2C) for the included OLED. So I want to move the I2C bus to different pins. I heard that the ESP8266 supports I2C on any pins. Unfortunately I can't find out how to do that in Arduino. According to the Arduino documentation for the wire library, there is now method to set the pins. Any hints? Re: Change I2C pins.
  3. Using I2C connections with the WeMos D1 Mini (ESP8266) Within IoT devices the I2C protocol is used a lot for multi-master multi-slave communication as a relatively simple serial bus. You will find that small sensors will report their data on the I2C bus. This means it can be important to know how to connect your IoT device to an I2C bus

The I2C bus is widely used to retrieve measurements or control equipment on Arduino, ESP32, ESP8266 and Raspberry Pi projects using the standard Wire.h library. The I2C bus is a serial communication bus developed by Philips from 1982 that allows two (or more) devices to communicate Interfacing ESP8266 ESP-01 module with I2C LCD The ESP8266 ESP-01 module has 8 pins only of which 4 can be used as I/O (input/output) pins (GPIO0, GPIO2, RX and TX), this number of I/O pins is not enough to run a 16×2 LCD screen which requires at least 6 pins. The solution is to add an I/O expander such as PCF8574 chip (I2C I/O expander) The ESP8266-01 is the smallest ESP8266 module and only has 8 pins. Of these VCC, GND, RST (reset) and CH_PD (chip select) are not I/O pins but are needed the operation of the module. This leaves GPIO0, GPIO2, TX and RX available as possible I/O pins, but even these have pre-assigned functions

Der normale ESP8266 verfügt lediglich über 8 Pins, von denen 4 als Datenpins verwendet werden können Arduino und ESP8266: Fallstricke bei I2C. Posted 8. Juli 2016 wp_blogadmin. Die I2C-Schnittstelle ist eine der einfachsten Möglichkeiten, eine Kommunikation zwischen Mikrocontrollern und externen Komponenten wie Sensoren oder anderen Mikrocontrollern zu realisieren.

ESP8266 Change i2c pins - Arduin

Beim ESP8266 stehen dir ähnlich viele Pins zur Verfügung wie beim gewohnten Arduino. Du hast die Möglichkeit, eine ganze Reihe Sensoren, Display oder andere Bauteile per I²C ( Inter-Integrated Circuit) anzuschließen. Auch die Kommunikation via SPI (Serial Peripheral Interface) ist kein Problem. Hinzu kommen eine ganze Reihe digitale Ein- und Ausgänge sowie ein Pin, um analoge Signale zu. I2C Pins . NodeMCU has I2C functionality support but due to the internal functionality of these pins, you have to find which pin is I2C. NodeMCU ESP8266 Specifications & Features . Microcontroller: Tensilica 32-bit RISC CPU Xtensa LX106; Operating Voltage: 3.3V; Input Voltage: 7-12V; Digital I/O Pins (DIO): 16; Analog Input Pins (ADC): 1; UARTs: 1; SPIs: 1; I2Cs: 1; Flash Memory: 4 MB; SRAM. Unlike most Arduinos, the ESP8266 doesn't have a hardware TWI, so I²C is bit-banged in software. This means that you can use any GPIO pins. By default, Wire.begin () initializes pins 4 (SDA) and 5 (SCL), but you can specify other pins using Wire.begin (int sda, int scl) So coming back to the ESP8266, I have attached snapshots of the part of datasheet that mention I2C details. Here the main thing is that the SDA or the data pin is actually the GPIO2 pin which is available in the pinout of the WiFi module. What about the the SCL pin? Well, we only have the GPIO 0 pin left as an available pin so we can assign it. Basic wiring. T h is basic wiring defines the I²C address of the MCP23017, provides it with power and connects it to the ESP8266. Just connect the following pins

ESP8266 NodeMCU I2C LCD. Let us now understand how the ESP8266 NodeMCU I2C LCD Interface works. If you remember the pinout of ESP8266 NodeMCU, D1 and D2 i.e., GPIO 5 and GPIO 4 are frequently used for I 2 C Communication. D1 (GPIO 5) is the SCL Pin and D2 (GPIO 4) is the SDA Pin. We have to use these two pins to connect to PCF8574 I2C LCD Module 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. 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. GPIO Pins NodeMCU/ESP8266 has 17 GPIO pins which can be assigned to functions such as I2C, I2S, UART, PWM, IR Remote Control, LED Light and Button programmatically. Each digital enabled GPIO can be configured to internal pull-up or pull-down, or set to high impedance I2C is perfect for I/O devices without a lot of available I/O pins, as it only uses two I/O pins. These LCD modules are common, but have a variety of addresses, so let's get you communicating with the ESP8266, connect the screen to the esp8266 module, and run a I2C address scanner to see what address we need to communicate with. The following steps will get you sorted I²C (I2C, IIC) is a serial 2-wire bus for communicating with various devices. Also known as SMBus or TWI, though SMBus have some additions to the I2C protocol. ESP8266 chip does not have hardware I²C, so module uses software I²C driver. It can be set up on any GPIO pins including GPIO16 (see below)

The pins used as SPI in the ESP8266 are: GPIO12: MOSI; GPIO13: MISO; GPIO14: SCLK; GPIO15: CS; PWM Pins . ESP8266 allows software PWM in all I/O pins: GPIO0 to GPIO16. PWM signals on ESP8266 have 10. Similarly, connect the Analog output pin to A0 pin of NodeMCU ESP8266. The I2C OLED Display has 4 pins as VCC, GND, SDA & SCL. So Connect VCC to 3.3V of NodeMCU & GND to GND. Connect its SDA pin to D2 of NodeMCU & SCL to D1. Source Code/Program. Here is a simple source code for Interfacing Capacitive Soil Moisture Sensor with NodeMCU ESP8266 OLED Display. Copy the code from below and upload it.
