How to change Adafruit SSD1306 splash logo?

Projects Programming
1

I was converting my bmp image with lcd asisstant and was doing some copy+paste in ssd1306.cpp file.
I just updated my library this morning and there are something changed on it.
Now i have a splash.h file and i tried many things to change the logo but i only got messed pixels everytime.

How can i change it ?

If you really want to change it, see Adafruit documentation about creating bitmaps: Arduino Library & Examples | Monochrome OLED Breakouts | Adafruit Learning System

Or switch to, the in my eyes superior, U8G2 library.

Thanks for reply but there is nothing with splash.h file in that page and also i got my hex bitmap file already.

Indeed there is not. But the splash screen is nothing more then any other bitmap on the screen (only with fixed dimensions). So if you made a fitting image (array) is as easy as copy past.

Just an answer for everyone who may end up here.

You need to edit the splash.h file in the Adafruit_SSD1306 library folder.

Edit the defines depending on your logo size like this:

#define splash2_width 128
#define splash2_height 32

Easy to oversee but if you have only scrambled pixels try "Horizontal" as Byte Orientation in LCD Assistant.

Its perfectly fine using hex values in splash.h, there is no need to convert it to binary format.
