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?
Cracked it - can connect the DS3231 to any 2 digital pins of my Nano and read the date, time, and temperature by making use of the B4A core library only. All control of the SDA (data) and SCL (clock) lines are hard coded. So, don't have to connect it to the traditional I2C pins and don't have to...
