### I2C Connection
Hook up SDA and SCL to any free GPIOs. Eg. [u8g_graphics_test.lua](https://github.com/nodemcu/nodemcu-firmware/blob/master/lua_examples/u8glib/u8g_graphics_test.lua) expects SDA=5 (GPIO14) and SCL=6 (GPIO12). They are used to set up nodemcu's I2C driver before accessing the display:
