Wiring is exactly the same as what we have done before, pretty much you just need to add another display to the same I2C pins of eitherthe Arduino or NodeMCU. For example, in some SDKs, this could be an IO input stream of the data (e.g., File.open(file, "rb")). Heres an example of the first option sending multiple files using the same name parameter: Notice that each file is put in its own part (separated by the boundary string). - First we are going to load the code to an Arduino Nanoconnected to a 128x32 display.
