I copied the attached program from the forum. The program was written by paraglider_nut. Being new to oled displays there are a few lines of logic I don't understand.
I went through and commented what I could understand. All the lines I don't understand I placed a question mark after them.
To begin with the message is not starting on the first line also, all four rows are scrolling left to right one pixel width and at the same time.
I wonder if someone out there could look at it an give me some advice.
Other than that the program works fine.
Also, how would you put variable data in the message.
