I am learning how to control ssd1306 oled by I2C, it works when I use the default SDA and SCL pins.
According to esp8266 document, "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",
I would like to change them to other pins, but it does not work. maybe I miss something to do?
Thanks in advance.
