Have you ever wanted to change the splash screen for a 128 x 64 OLED display? The Adafruit libraries include something but here's how to change it. I created an XLS to generate the display code, just enter 1 and 0 for the pixels you want on or off. Here's how to use this SSD1306 splashscreen code generator
Get the excel file https://drive.google.com/open?id=0ByEQKtsOckWBV3JEa3JKUGktTlU
-
Open the Excel file (Office 2010), on the tab Code Creator, in the highlighted cells, enter a 0 to turn that pixel off, 1 to turn it on, do this for all 128 x 64 pixels, note the 0 or 1 will be invisible
-
On the tab Code Creator, copy cells A3 to A72 to the clipboard (this is the entire buffer[] definition)
-
open the file Adafruit_SSD1606.cpp and select all code for the "static unit8_t buffer" definition, and overwrite that code with the stuff on the clipboard (just paste on the selected code)
-
save the .cpp file and recompile your sketch
-
check adafruit licensing before changing the splashscreen
Here's an example of the Excel user interface, the OLED 128 x 64 will look the same.
Enjoy!
