 If you are using the 128*32 small displays, then you will be using separate I2C busses and having the same address for each OLED does not matter.  If you are using the 128*32 small displays, then you will be using separate I2C busses and having the same address for each OLED does not matter. 
  
-{{:users:dagnall53:img_2757.jpg?200 |Preferred OLEDS set to two addresses}} If you plan on having two 128*64 displays, then my code assumes that one will be set up as Address '60d' (as it came from the shop) and the second display will be Address '61d' (Because you make a small change to the display, move one resistor.). +{{:users:dagnall53:img_2757.jpg?200 |Preferred OLEDS set to two addresses}} If you plan on having two 128*64 displays, then my code assumes that one will be set up as Address '60d' (as it came from the shop) and the second display will be Address '61d' (This requires you to make a small change to the display, just move one resistor.). 
 (For some reason, the displays have the address printed as '0x78' and '0x7A', but I will refer to these as '60d' and '61d', as this how the code "sees" them.) (For some reason, the displays have the address printed as '0x78' and '0x7A', but I will refer to these as '60d' and '61d', as this how the code "sees" them.)
 The display on the left has been adjusted to '61d' Note that in the photo, the light caught the moved resistor, - it is not a solder blob across the pads, but the edge of the resistor catching the light. The display on the left has been adjusted to '61d' Note that in the photo, the light caught the moved resistor, - it is not a solder blob across the pads, but the edge of the resistor catching the light.
