I am trying to get i2c to work on my ESP8266, but don't have much luck. I must be missing something. Maybe someone here can help me. I tried I2C1. setup({ sda: D12, scl: D14 }); I2C. find(I2C1); =undefined I put 10k pull-ups on both GPIO12 and GPIO14 Correct me if i am wrong but I was assuming that the I2C. find command is similar to i2cdetect and should return a list of I2C compatible devices

ESP8266 with two BME280 Sensors over SPI. August 26, 2017 2605. I had a problem with the wiring on this one. With SPI you use the same pins for SCLK (SCL pin on the BME280 boards) , MOSI (SDA pin) and MISO (SDO pin) and then each SPI sensor has to have its own CS (CSB pin). sensors have the same connectors for everything except the CSB

Wiring NodeMCU ESP8266 12E with i2C 162 LCD Screen

I2C bus is a means of connecting several peripheral input and output devices that support I2C on two wires. One of those wires is the DATA line called the SDA, whereas the other is the CLOCK line called the SCL. The information is sent on these two lines using what is called the I2C communication protocol.
